With all of the changes Google made in the past year, it is easy to get mixed up as to what changes affected what areas of a site’s SEO information, and what was penalized by which algorithm updates. Combine that with a disavow links tool which most don’t seem to understand, and it is a wonder anyone can keep up with Google’s updates.

Pratik Dholakiya, writer for Search Engine Journal, recognized how confusing this all must be, and sought to explain which types of updates affected what, as well as all of the misconceptions surrounding these updates. He breaks them down into three basic types of updates, and each focused on different aspects of SEO.

EMD Algorithm Update – The September update targeted sites with exact match domains (EMDs), or sites named after keywords instead of brands. This change didn’t so much penalize most affected as it removed a special boost they were receiving due to the name of the website.

The only people really penalized by the update were those who had over-optimized their site around the keyword. There is also a misconception the EMD updates were Panda or Penguin related, but Matt Cutts has put that idea to rest.

 

Panda Updates – The main area the Panda updates looked at was your on-site content. Google was trying to weed out low-quality or duplicate content, and they’ve been churning out constant new versions of Panda all year.

Penguin Updates – Despite the close association with Panda, Google’s Penguin updates are actually their own beast, formerly known as the webspam algorithm update. They are targeting all of the spammy sites out there, and unless you’re a spammer, the only penalties you may have seen from these updates were from links.

If you have seen any penalties from these updates, Dholakiya explains how to help fix the problems. The Disavow Links tool can help with that, especially if you’ve seen penalties from the Penguin updates, but it isn’t a magic solution.
