Major Adsense Change From Google
Google this week made a major adjustment to its Google Adsense program which in my opinion has not received enough attention within Internet affiliate circles.
Google has redefined the "clickable" region of Adsense ads. This essentially means that instead of making the entire ad being displayed clickable, just the headline and URL will be linked to advertisers sites. Google Blogoscoped has a good before-and-after visual of the Adsense area change.
Now while that may not seem like much of a development, it's actually pretty substantial - for Adsense publishers and Google itself. By reducing accidental or errant clicks, invalid clicks to advertisers sites (those which don't convert to buyers, leads, prospects) will be much fewer and reduce the heat of the click fraud issue. For publishers however, this could potentially mean a lower click-through rate on their ad units and over time lower earnings.
