Time to shift gears a little bit. In this lesson, we'll mainly focus on what is known as the Panda update. Well, not a traditional algorithm update as we've been discussing, Panda nonetheless, had a huge impact on the search engine landscape. After this lesson, you'll be able to recognize a variety of pages that are of concern to an SEO, and learn about how to avoid being targeted by Panda and updates like it. The first algorithm update I would like to discuss is known as Panda. Rather than a one time change, this is a search filter, which means you will continue to see updates rolled out from time to time. This algorithm was created to prevent sites with low-quality content from ranking well in search. Because this is updated on a somewhat regular, though unpredictable basis, this means that if your site was previously penalized during a Panda update, but you took the time to improve your content and make the appropriate changes to your website, you can begin to recover from the penalty. Ongoing updates will also help catch and penalize sites that may have escaped past updates. Lately, rather than seeing specific updates, Panda is rolling out more slowly over several months at a time. Google has confirmed that this is due to an internal issue related to technical updates. Previously, the filter would be applied over a few days time, and webmasters would immediately know if changes to their website was due to a Panda update. I recommend you watch the provided Google Hangout video where Google's John Mueller addresses questions related to the Panda rollout. This starts at the beginning of the Hangout and ends approximately seven minutes in. The link is provided in your study materials. What we know of Panda is that it targets low quality or thin sites. Thin sites means that the site has very few pages that contain content useful or informative to users. This could mean that you have pages which contain largely the same content, pages with no content, pages that lead to forms or pages where content is syndicated or scraped from other pages on the web. To get a better understanding of what Google uses thin content, read the Google support page titled, "Thin content with little or no added value" and watch the embedded video. I have provided a link to this resource in your study materials. Another thing Panda will look for is duplicate content. This can mean pages you have duplicated within your own site, or pages you have scraped content from and placed on your site. Since these duplicate pages offer no additional value, they don't rank well. Duplicate pages on your own site, will end up cannibalizing one another and then neither will get the rankings they deserve. Generally, when it comes to content duplicated or scraped from another website, the website that first published that information will receive credit and will rank for that content. The site copying of the content will not rank well, and in some cases, if you have massive amounts of scrap content, your site will be penalized. Additional things that we trigger a Panda penalty are excessive amounts of ads on the site. If you have a page with very little content that is surrounded in advertisements, that isn't providing a lot of value to a user, then the page will not rank well. This would be considered a thin page. Google will also look at things like your site navigation. Whether or not the navigation is intuitive, and if it links to all of your content. You really want to make sure you're providing a good user experience for your users. Google has published a post on their official blog, that provide some guidance on what you can do to build high-quality sites. I recommend reading the post of the link provided. The initial Panda rollout surprised a lot of webmasters and SEOs. We knew that the trend of updates had changes which were meant to get webmasters to provide more value to users. But the update hit several websites hard. Many never recovered. The website Pandalized.com, was created to keep track of how Panda effected large sites. Several well-known sites were severely impacted when this algorithm rolled out, and some never returned to normal. Here are some charts from the site, and you can visit the site directly to see more examples of how the Panda filter affected these sites. Some examples of the type of content Panda targets, includes things like automatically generated content. Automatically generated content, is also referred to as spun content and it's content that is created by a program and inserts applicable keywords. But most often the articles gibberish are very poorly written and it's difficult for users to understand. Another type of content targeted by Panda are squeeze pages. Squeeze pages are like a landing page, where it's one main page that features all of the content and you have to just keep scrolling down for more information. The content is usually broken up by forms and by now buttons. You will sometimes run into sites which you cannot easily exit due to pop-ups asking you to cancel. Another issue Panda looks at our doorway pages. Doorway pages are pages which are built for search engines rather than users. These pages often rank for one thing, and then when clicked on, will redirect the user to a page or a site about another topic. This is usually done for commercial or malicious intent. In order to get the page to show in search engines, webmasters would often use what is known as a meta-refresh. Which means that once you land on the site, it will then refresh to another site before you can hit the back button. Google began penalizing sites using the meta-refresh technology. Then webmasters began using JavaScript, or tricking the visitor into visiting the desired destination through creative linking. Panda also began penalizing low quality guest posts. Because getting links to your site is very beneficial for SEO, a trend called guest blogging became widespread. Unfortunately, as things do when they get popular, some individuals began taking advantage of this and created low quality sites dedicated to guest posts on a variety of subjects. This caused Google to sit up and take notice, and they began to penalize sites that published these low-quality posts. Unfortunately, some good sites where you could go and find writers to guest post on your blog were also caught in the crossfire. Basically, to avoid being penalized by Panda, view your site as a user would view it, look at what information is helpful and valuable to them, and what might be a unnecessary information that would be better served elsewhere or just removed entirely. Always ask yourself how your site can differentiate itself from other sites and add value.
