Over at Search Engine Roundtable, Barry Schwartz points to a Webmaster World thread which compares the Google AdSense information from each of Google’s quarterly earnings reports dating from Q4 2003 until Q1 2007.

The comparison shows a dip in total revenue share for Google AdSense publishers from Q3 2004 until Q3 2006, then a sharp increase in Q4 2006 and Q1 2007.

According to the comparison, Google AdSense revenue sharing is at its peak since the introduction of Google’s contextual advertising network.

Why the increase? It could be because of many factors including:

• Higher quality of publishers & partners
• More strategic partners with negotiated revenue share
• Higher share due to competition at YPN, Federated Media and other ad formulas
• The introduction of image and video advertising in Google AdSense

Have you seen a change in your AdSense revenue?
