If you are a Search Marketer or someone who likes to stay up-to-date with Google’s ever changing algorithm (not sure who that covers), then the end of September and early October has definitely kept you busy. Google has made new updates to its search engine to improve the user’s experience and to rank pages higher that have the authority, authenticity and information that people are searching for.  These four new recent updates include:

“Top Heavy 2” – launched October 9, 2012

This is a page layout filter update that penalizes ads and links that are featured prominently at the top of a site, oppose to high quality content.  This update is called, “Top Heavy” due to sites containing pages that are top heavy with advertisements.

Penguin Update 3 – launched October 5, 2012.

Penguin is the spam fighting algorithm and the third content refresh happened this week.  The update affects pages with low quality inbound links and works toward removing spam pages from top search results.

The EMD Update – launched September 28, 2012.

The Exact Match Domain (EMD) update will reduce low quality exact match domains in the search engines.  For example, a New York based lawyer with the domain name, newyork-lawyer.com/

However, this is aimed specifically at low quality websites. If a domain has exact match keywords but the site is legitimate and playing by Google’s rules in all other aspects of web marketing strategy, this is not going to pose a problem for the business.

Panda Update 20 – launched September 27, 2012.

This is a data refresh and an algorithm update that will give precedence to high quality web writing, while penalizing sites that have low quality content writing that has been purchased from content farms or is filled with outdated, “keyword stuffing” strategies.

The update works toward providing search engine users with helpful, fresh and valuable information, when they search in Google’s engine.

For all future updates to Google’s ever changing algorithm be sure to follow the Twitter feed of Google’s head of the web spam team Matt Cutts for continual updates, or check the Google blog daily for any updates or announcements that might have an effect on your website.
