Many of Compendium's older clients and industry friends remember that Compendium began as an SEO-focused blogging platform. Over the years, the platform has expanded to cover many other facets of content marketing with enterprise-level management tools. We certainly haven't lost any of our search optimization features and functionality, but some clients and partners have asked how we've responded to Google's latest algorithm changes, specifically last year's Panda and this year's Penguin.
In regards to platform changes, Compendium hasn't made any changes based on Google's algorithm updates. Our platform has always been extremely indexable and search friendly. We firmly believe that content is king. Creating engaging, quality content with semantic HTML is the core of all SEO best practices. Nothing Google has done has required any changes to our SEO philosophy or platform behavior.
The changes have reemphasized our conversations with our clients regarding content quality. Panda, which began rolling out on February 23, 2011, primarily targeted websites with thin content or high ad-to-content ratios. Several rounds of updates and revisions to the Panda filter has been released since then. Penguin, released on April 24, 2012, is known as an "over-optimization" penalty, cracking down on keyword-stuffing and other spammy tactics. Our account management team continually coaches clients to maintain a high standard for their content writing and avoid the overuse of keywords. In fact, our message meter feature can warn authors of high keyword usage.
The proof is in the data, though. Below is a roughly growth-adjusted chart of Compendium's platform-wide Google search traffic. You'll notice that traffic continues to grow over time as content and age increases, and none of the major Google updates have had a platform-wide impact. In fact, the algorithm changes may have had a positive impact for our clients as they've decreased competition within the search results.

I hope that helps! Visit Compendium.com if you're looking for an effective content marketing platform that will help, not hinder, your search efforts and increase the effectiveness of your overall content marketing strategy.
