Speed is Everything

Page loading speed has great importance with Google these days. From mobile visitors to Googlebots, every visitor will appreciate a speedy experience. Here are some ideas to keep in mind: 1. Rise of mobile The importance of mobile can be seen in Google’s announcements the last few years. Mobile users are more impatient than ever, and Google provided stats last week regarding just how impatient mobile users are: – The average mobile page takes 22 seconds to load, but 53% of users leave after 3 seconds! – Even mobile landing pages in AdWords were found to take 10 seconds loading time. There are many easy changes available for sites to make, as the answer isn’t always in purchasing a faster web server. Google’s own analysis found that simply compressing images and text can be a “game changer”—30% of pages could save more than 250KB that way. 2. Ranking factor A few years back, Google made page speed a small ranking factor – or at least they were finally explicit about it being a ranking factor. Since page speed issues aren’t given the exposure of crawl errors and other items in Google Search Console, it can be easy to put them on the “long list” of items to fix. Its addition as a ranking factor is a great signal that this needs to be prioritized. 3. Bounce rate Nice try, loading up your site with images that take forever to load. Unfortunately, that doesn’t increase the duration of site visits. It just makes people angry. According to Google’s analysis, every second of loading time, from 1 to 7 seconds, increases the chance of a bounce by 113%! Many SEOs believe that “engagement metrics” such as bounce rate could also be a ranking factor. And it makes sense: When Google sees a rise in organic bounce rate, they know human visitors are judging the content. How could Google not take this data into account? 4. Crawl rate In one recent test, increasing page speed across a site dramatically increased the site’s crawl budget. Slower sites can be overwhelmed by crawl activity. But if you ever feel the need to put a crawl delay in your robots.txt, take that as a warning sign. After all, even reasonably fast sites can often need more crawl budget. Tools and Fixes Luckily there are remedies. Some can be quite easy, such as adding compression to your web server. Others might require a trip to Photoshop for your site’s images. However, some items will not be worth fixing. Try to concentrate on the easiest tasks first. Run an analysis of your site through these two tools and see what you need to fix: Google’s newest tool: Test how mobile-friendly your site is. GTmetrix.com features include a “waterfall” showing which page items load at which stage, history, monitoring, and more. Good luck and enjoy optimizing the speed of your site!

Google Analytics Doesn’t Provide all of the Answers

Google analytics has become a great source of data about visitors to your website – assuming your configuration is correct. Sometimes configuration issues inadvertently block your view of what is really happening. Common issues can include… 1. Not having your analytics snippet in the correct place.   There are many legacy variations of the analytics snippets. In addition, what was the correct installation a couple of years ago may have dramatically changed, depending on if you have an asynchronous snippet, etc. We still run into snippets calling for urchin.js for their Google Analytics, which are quite a few years old. The best place  – currently – to have your analytics code is inside the <head> tag, and right before it ends with the </head> tag. This will prevent interference with other scripts, which we have seen mess with bounce rates, conversion tracking, ROI, sleep schedules, general happiness, and more 2. Filters Your filters could have been created years ago and for long forgotten purposes. In Google Analytics, check your Admin area (under view, on the right halfway down) to see if you are filtering traffic. Look at the filters – do you know who created them and why they are present? Some have complicated REGEX rules and it can be difficult to decipher. Everyone should have at least one profile with no filters. We usually name this profile with RAW in the name. This system allows anyone to easily see if a filter has “gone rogue” and is filtering out good traffic. There are also these problems with getting good data, and you did not even cause them: 1. Incomplete data / views Most businesses are using the free version of Google Analytics, and sometimes experience “sampling” in important reports. Sampling in Google Analytics (or in any analytics software) refers to the practice of selecting a subset of data from your traffic and reporting on the trends detected in that sample set. Sampling is widely used in statistical analysis because analyzing a subset of data gives similar results to an analysis of a complete data set, while returning these results to you more quickly due to reduced processing time. In Analytics, sampling can occur in your reports, during your data collection, or in both place. (Image of sampling) 2. Organic keywords Years back, Google Analytics allowed you to see the query typed in by visitors. It was so powerful! It allowed you to see quite a bit of information about your prospects – perhaps too much. It has now become standard that search engines, browsers, and analytics itself is restricting this information. If you are new to analytics, you probably have not missed what you do not have. However, if you have been doing this a while, take a second to reflect on what was lost. We are right there with you. Hmph. 3. Referral spam, organic keyword spam, language spam In addition to losing out on good data, there is often too much noise in otherwise good data. Using fake browsers – bots that can run analytics code, all sorts of things are being inserted into your analytics. Some of the offenders might put – “Vitally was here” in the list of languages your visitors use – or make it look like visitors are coming in droves from some site you’ve never heard of (which is either selling SEO or hosting malware). Spam is analytics has become a major nuisance and we constantly have to deal with it while compiling reports. We see the same offenders across multiple accounts, and create a custom analytics segment to filter them from reports. Want to try our segment?

9 ways to get the sitelinks you want (and deserve!)

Organic sitelinks are the sub-links that appear under your homepage URL in search queries specific to your company. Matt Cutts explaining how sitelinks are generated: A typical company listing has 4-6 sitelinks meant to help users navigate your site directly from the search engine results page, rather than having to click your primary URL to navigate. Some URLs may have up to 12 sitelinks below the primary search result! Organic sitelinks are great for users (and for you!) There are many key benefits to organic sitelinks: Users can quickly and easily gain access to a better-suited landing page than the homepage. This quick navigation option is great for the user and it reduces your organic bounce rate too. Sitelinks provide a large presence on the search results pages. PPC Hero did some research into sitelinks, and found that, why they’re not clicked as often as the primary link, they do provide additional CTR and conversions. Read more the PPC Hero study. Showing 64% increases in PPC ad Click-Through-Rate with sitelinks Having numerous – and well-crafted – sitelinks helps to make your brand look more popular. Big brand tends to have more, and better, sitelinks. 9 tips to get the sitelinks you want (and deserve!) Typical sitelinks include a Contact Us page, plus other pages that look important to Google. However, Google often misunderstands what the key pages are on your site! That’s why it’s crucial that companies watch over and adjust their sitelinks. While you can’t specify sitelinks directly to Google, and they don’t disclose exactly how they choose organic sitelinks, there are key tactics you can use to get the sitelinks you want (and deserve!): Be #1! You will typically only get sitelinks for branded searches, such as for your company name. Sometimes the #1 result will get sitelinks as well, but it’s typically branded queries. Submit a sitemap.xml in Search Console (formerly Webmaster Tools). This appears to be a necessary step before sitelinks are “granted” by Google. Demote undesirable sitelinks in Search Console (formerly Webmaster Tools) if you find that any are showing up. To demote a sitelink URL: On the Search Console homepage, click the site you want. Under Search Appearance, click Sitelinks. In the For this search result box, complete the URL for which you don’t want a specific sitelink URL to appear. In the Demote this sitelink URL box, complete the URL of the sitelink you want to demote. You can demote up to 100 URLs, and demotions are effective for 90 days from your last visit to the demotion page (no need to resubmit – just revisit the page). Look at what you’re linking to sitewide (stop linking or do nofollow), especially in your main navigation elements. Googlebot seems to like lists of links, including H2 tags with links to sections or pages and bulleted lists of links. Learn more here: http://www.seerinteractive.com/blog/get-organic-google-sitelinks-long-form-content/ Use rel=nofollow. Sometimes, privacy policies show up as sitelinks because they have a link on every page of the site. Use a rel=nofollow on pages that Google is incorrectly choosing as sitelinks. Optimize your pages. Ideally, your best pages should already be optimized, but make sure titles and meta-descriptions are in order. Inbound links look at where other sites are linking to (change your redirects or outreach to other sites and ask them to update their links). Googlebot prefers popular pages, including landing pages with volume in analytics. Organic sitelink takeaways While there is no direct formula for sitelinks, these tips can help you better communicate to Googlebot what you would like to show up for your brand. Since search results are often very personalized and based on Google’s algorithm, it may be that certain sitelinks appear for some users, but not for others. PSST!

Conversion is King

Content is helpful, but conversion is everything. The point of content – and usability in general – is to meet business objectives. Any business objective can be a conversion of sorts: bookmarking, social sharing/liking, video views, time on site, lead generation, add to cart, and hopefully even completing the sale! By measuring each step, brands can understand where their site can improve it’s usability and contribute more to the bottom line. 1. It can be easier to increase conversion than to increase traffic Increasing conversion also increases revenue, and can be easier than increasing traffic – up to a point. 2. Even mobile apps can easily conduct conversion optimization tests Mobile testing platforms now allow conversion and usability testing without rolling out new versions of your app. Solutions exist from Optimizely ,Visual Website Optimizer (VWO), Liquid, and Artisan Optimize Mobile App. 3. You should test EVERYTHING User Experience professionals agree: Take their advice, but “always keep testing”. Conversion case studies show all sorts of factors can influence conversion: Logos and headers Design style of the the site Product page designs Product descriptions and overall copy writing The text of your call to action buttons Images Use of video (usually boosts conversion, but not always!) Purchasing path through the site 4. Website redesigns should use, not reset your data Now if the site is just awful, start with a redesign. But a website redesign that starts over can sometimes be a horrible waste: Another shot in the dark, with hope and prayer. Consider instead a redesign process based on evolving the website with small changes, continually tested for improvement. But definitely start from having your website in a “good place”! Not sure of next steps for your site? Time to start testing – or maybe a redesign from that “good place”. Need a good interactive agency or website design firm?

Kick-Start Your SEO in 2015

The search engine optimization (SEO) industry has certainly evolved these last few years. The many Google updates – and their sometimes heavy-handed penalties – in addition to an explosion of mobile traffic have shaped the rules for SEO and online marketing. When we look at what’s working at the end of 2014, we see just how much everything has changed. Big changes in SEO will certainly continue for 2015 and beyond. Here are six things to focus your efforts on in 2015: 1. Mobile If you haven’t already, it’s time to take a mobile-first approach with responsive website design. As mentioned in last month’s blog all about mobile, Google has a new tool (and new expectations) around mobile friendliness. Test your site here:https://www.google.com/webmasters/tools/mobile-friendly/ 2. Rich SnippetsThese underlying webpage code elements help Google and other sites understand when to show review stars, customized descriptions, and more. All of which are vital to your site ranking and click through rate. Consider: A study last year showed an average rankings increase of 4 positions when rich snippets were implemented. In one case study, 30% more visitors clicked through from search results to a site with rich snippets. John Mueller of Google recently requested that examples of rich snippet “spam” in Google be sent directly to him. It must be working, and it must be valuable, if Google is looking for spam! There are many examples of different rich snippets at http://schema.org, a site and format created by Google, Yahoo and Bing. Some types include recipes, products, events, locations, people, ratings, etc. And other formats are also being provided by social media sites: Facebook open graph tags, LinkedIn cards, Twitter cards, and even Pinterest pincards. Consider how this tweet of a site using twitter cards looks better than the standard tweet: When twitter is given data in a twitter card format, they provide a much richer experience for viewers of that tweet. And there are many different types of twitter cards too: Galleries, large images, video players, etc. 3. Universal Analytics Google analytics is finally getting an upgrade. In the past, data about site visitors was lost if they visited several of a brand’s website properties, switched devices, or had an extended period of time between visits. Universal Analytics fixes that and even allows custom dimensions, as well as extreme customization. The system came out of beta testing in 2014, and will be a requirement at some point. Is it on your radar to transition? If not, better get to it! Google will not be providing new features to regular analytics and will eventually force webmasters to make the switch. 4. Link Disavowal Google’s Penguin penalty has made this a necessity. Do you know where your site has links? Most webmasters do not. And many links that were key in the past must now be disavowed in Google’s Webmaster Tools. That is the price we pay for Google’s ever-changing formula! Here are some possible sources of problematic links: “Site wide” footer linksAre other sites linking to you from every page or in their footer? Google no longer sees this as a positive thing. Links from 2004-2012If your SEO plan included creating links during this period, you should get a link analysis performed. Even if Google’s guidelines were being followed, it’s vital to make sure these links are still the kind Google wants to see. Low quality linksYou know these when you see them. Would you visit the site a link is on? Does Google still see any authority there? These are important considerations for your links! Links from penalized sitesSites that were once in Google’s good graces might now have switched hands or been penalized. Negative SEOSEOs used to debate whether any site’s rankings could be hurt from the outside. Now, it’s commonly accepted that negative SEO is possible and happening throughout the web. Some sites are building low quality links, links on penalized sites, etc. pointing to competitors’ websites! 5. Migrate Your Site to HTTPS Are you planning to migrate your entire site to HTTPS? Recent thoughts from Google are making this a more important consideration! A member of the Google Chrome browser team recently commented that anything less than HTTPS is like leaving the front door unlocked. On the search side, HTTPS has been identified as a minor ranking signal – and migrating your site should be considered. Be sure you don’t create duplicate content by accident though! 6. Use Content Marketing for Link Authority Content marketing is  the new link building. It’s authentic marketing that can also boost your site’s rankings (but it must be done with an emphasis on quality outreach). When done correctly, content marketing brings: social sharing brand visibility inbound links (with authority) referral traffic Search Engine Optimization will always be ever-changing: Technology is moving at breakneck speeds and search engines have ever-changing criteria and expectations. Having these six items on your radar will help carry you nicely into the new year. And then some. The year 2016 may be completely different, but these are good solid investments of time and money.

Google Moves Against Guest Blogging – March 2014

Google made two more moves against guest blogging in the last month: 1. Google penalizes a site connecting content marketers and webmasters Content marketing is all about getting your information out to interested webmasters. Google recently penalized a site that simply connects those with content to those with websites. The content varied in form: guest posts, infographics, eBooks, etc. What was the issue exactly?! Having a meeting place to connect great content with great websites SHOULD be win-win. It’s a much better option than spam email hawking content or seeking links from any webmaster that will listen. So, is it wrong to try to connect authors and publishers? Is the editorial value of a link lessened where it was easier to connect to the webmaster? 2. Google penalizes an entire website based upon one guest post it considered off-topic Doc Sheldon, a longtime SEO copywriter, was penalized based on a single guest post he hosted. The posting was about social media to Hispanic audiences, but aroused the interest of Google. And not in a good way. Social media marketing is closely aligned with SEO, and the penalty feels arbitrary – if not confusing. Is Google spreading Fear, Uncertainty and Doubt? Only one thing is clear: Webmasters and business owners are being held accountable 100% for the content on their own website. So what to do? Create a content generating, curating, sharing machine. Sharing content can be a minefield these days, but a safe way forward is: 1. Post full versions of your content to your site, but also Google+, LinkedIn, and promote your content at other relevant places around the web. 2. Tag your content with rich snippets, Facebook open graph, and Twitter cards to increase it’s “sharability” and categorization.

Spam-Fighting Always Continues – December 2013 Summary of Search

Spam-Fighting Always Continues Google’s Matt Cutts promised a month free of major updates, but added that “spam-fighting always continues.” Indeed, there were some complaints from webmasters around the 17th and 19th that could have been Google taking out another link network. This month, Google made an example out of Rap Genius. The site was offering traffic for blog links. To participate, you had to link to their Justin Bieber page. And somehow feel good about yourself. Oh, and send them the link. Rap Genius would then tweet your link to their followers, sending traffic to your blog. Google caught wind of the link scheme, and severely punished Rap Genius in the rankings. The moral is that Google will always, usually, catch you! So how do you invest in search engine traffic for the long term? 1. Create Content Google wants compelling content: images, blog posts, videos, podcasts, surveys and more. Good content is long (1000 words plus for articles) and holds your visitor’s attention. Google does not want visitors leaving the site quickly (but will probably forgive if it’s an ad click!). 2. Tag Your Content Search engines are getting better at understanding what we humans create on the internet. But communication directly with “search engine bots” has never been easier. These technologies could be better implemented on almost every website: – Internal linking structures – Sitemap.xml – Title tags – Meta descriptions – Rich snippets   – Authorship 3. Get the Word Out Content outreach and marketing has never been more important. Content today is where websites were in 1998: Many build, and then are disappointed at the results. Good content competes against a dizzying array of distractions in an always-connected world, and must be actively marketed – even AGGRESSIVELY marketed – to make an impression. Content must be spread via social media (especially Google+), and marketed specifically for links. These are “earned links” and outreach for the purpose of links wonderful way to promote your content. As a bonus, this promotion of content will also promote rankings!

Notes on the Yahoo / Bing Transition

Yahoo advertisers received an email outlining a few more terms regarding the upcoming transition to the Microsoft Advertising adCenter platform. Some quick points: 1. A Tab will show up in “YSM later this month”, so be sure to login and look around. 2. Yours ads can server in adCenter right away when you transition. 3. Silverlight will continue being used. I still need to test and see what functionality might be missing when I login from my iPhone or an older mac. I hope whatever missing features degrade well! 4. The upcoming changes to organic search are later this month. We anticipate a rocky ride, as Microsoft will likely need to make ongoing tweaks. Dear Advertiser, As your transition to the Microsoft Advertising adCenter platform approaches, we have more details to share to help you prepare for the changes to come. Considerations for your upcoming transition adCenter account Soon, you’ll need to either create a new adCenter account, or link an existing adCenter account to your Yahoo! Search Marketing account. Later this month, you’ll see an “adCenter” tab within your Yahoo! Search Marketing account. Clicking there will take you to the beginning of the account transition process, where we’ll walk you through the simple steps to create or link accounts. Budgeting Once you create your adCenter account, it will be active and your ads will be eligible to serve on Bing right away. As a result, you’ll be managing both your new adCenter account and your existing Yahoo! Search Marketing account in parallel until ad serving for Yahoo! traffic transitions to adCenter, so plan to budget accordingly. Microsoft Silverlight With Silverlight installed, you’ll be able to see and address key differences between your Yahoo! and adCenter accounts as you transition. Download Silverlight now. Organic search transition Yahoo! organic search results will be powered by Bing as early as late August. If organic search results are an important source of referrals to your website, you’ll want to make sure that you’re prepared for this change. For more details, check out this blog post. As we’ve stated previously, our primary goal is to provide a quality transition experience for advertisers in the U.S. and Canada in 2010, while protecting the holiday season. However, please remember that as we continue to go through our series of checkpoints, if we conclude that it would improve the overall experience, we may choose to defer the transition to 2011. We are committed to making this transition as seamless and beneficial for you as possible. We appreciate your business, and look forward to bringing you the benefits of the Yahoo! and Microsoft Search Alliance. Sincerely, Your Partners in the Search Alliance, Yahoo! and Microsoft

4 reasons to 301 redirect old subpages ASAP

After a major website redesign, it’s not uncommon for page locations and even page extensions to change. Maybe you’ve switched web development languages, or changed your website’s structure into a SEO friendly themed set of silos. Whatever the reason page locations have changed, it’s vital that the old page locations are 301 redirected to the appropriate new pages. It’s time sensitive for the developers to make the change, as: 1. Pages will start dropping out of the index (Google hates sending visitors to bad pages, and can see the bounce rate skyrocket). When Googlebot comes to visit your site, it will probably receive a “404 Error Page” as well as a 404 HTTP error code. A 404 error code is the surefire way to get a page out of Google’s index. 2. Humans that have bookmarked the old page will be stranded. Depending on the 404 error page (Your server’s default is simply awful), your loyal return visitor may think the entire site is down. 3. Search engines will stop counting the power of the links coming into broken pages, and rankings will drop. Search engines do not count links to missing pages. The wonderfully diverse link profile you’ve built over the years can disappear as links to subpages are no longer counted. 4. Webmasters linking into subpages might notice the 404 and remove their links. Some webmasters routinely monitor where they are linking to, and remove links to broken destinations. Don’t make the most common of 301 redirect errors: Sending everything to the home page. to preserve a diverse link profile, you’ll want to keep those links spread naturally across your site’s homepage AND subpages. Happy 301 redirecting!

13 Reasons Why Google Loves Blogs

Google loves blogs. What is it about blogs that Google loves so very much? We’ve pinpointed 13 reasons why Google may give – or appear to give – sites with blogs a little extra boost in rankings. Of course, the list is broken down into our framework of looking at good quality sites as being accessible, relevant, and popular. Accessibility: Search Engine robots must be able to find your content. These reasons help the bots find your postings without a lot of muss or fuss. 1. Pinging Most blog software sends out a “ping” when there is a new post. Instead of waiting for a search engine crawler to come across your site’s new content – either via a routine crawling or via a link – a notification is sent out to sites like pingomatic, technorati, and even google blog search. This notification tells the search engine robots to come and fetch some fresh (crunchy) content. 2. RSS feeds provide deep links to content RSS Feeds are useful for so many, many things. They contain links to your latest postings, but also consider that they contain links right to the postings themselves. Even crawlers that aren’t that smart (you know who you are, little bots!) can figure out how to find a link in a list. That’s essentially all an RSS Feed is: A list of links in a predictable format. Hint: You subscribed to your feed in iGoogle, didn’t you? 3. Standard sitemap.xml provide deep links to content If an RSS feed isn’t enough, use a sitemap.xml file to notify search engines about your site, including any new posts. A great thing about sitemap.xml files is that they can communicate additional information about a link, like how often a search engine robot should visit and what priority the page has in relation to your site. 4. Based on modern HTML design standards Most blogging software was created or updated very recently, and doesn’t use outdated HTML methods like nested tables, frames, or other HTML methods that can cause a bot to pause. Relevance: Once found, search engines must be able to see the importance of your content to your desired audience. 5. Fresh content, updated often Nothing quite gets the attention of a search engine robot like fresh content. It encourages frequent repeat visits from both humans and robots alike! 6. Fresh comments, updated often Of course, the blogosphere is a very social place. Googlebot is likely to come back often to posts that are evolving over time, with fresh new comments being added constantly. 7. Keyword Rich Categories, Tags, URLs Invariably, some of your best keywords are likely to be used in the tags and categories on your blog. If you aren’t using keyword rich categories and tags, you really should be. Popular: Google looks at what other sites link to your site, how important they are, and what anchortext is used. 8. RSS Feeds provide syndication RSS Feeds can help your content and links get spread all around the internet. Provide an easy path to syndication for the possibility of links and, of course, human traffic. 9. Extra links from blog & RSS Feed directories The first blog I ever started was for the possibility of a link from a blog directory. But RSS Feed directories exist too! Be sure to maximize the link possibilities by submitting to both. 10. Linking between bloggers / related sites Blog rolls are links that blogger recommend to their audience. sometimes they have nice, descriptive text and even use XFN to explain relationships between bloggers. Some of your best human traffic can be attained through blogrolls. 11. Social bookmarking technologies built in Blog posts are usually created with links directly to social bookmarking services like delicious.com, stumbleupon, and other social bookmarking sites. You’ve never made it easier for your audience to share your posting and give you a link! 12. Tagging / Categories with relevant words Tags can create links to your blog by relevant pages on technorati and other blog search engines. These tag pages sometimes even have pagerank! They deliver keyword rich links and quality traffic. 13. Trackbacks (Conversations) Trackbacks are conversations spanning several blogs. They are an excellent way to gain links (although often nofollowed these days), and traffic. Other blogs can be part of the conversation, thanks to the trackback system!
