Jason has a theory that click values in Adsense have increased since the introduction of the Yahoo Publishing Network and writes:
‘Just got that comment from a Adsense publisher. I can tell you we did see an up tick the last two days. I can’t get into exact details because of Adsense TOS. However, last week we set a single day record with ~$2,450. The last two days we did $2,913.23 and $3,070.11 with just a couple of more clicks (yes, that puts us way above the $1M yearly run rate… yahooooo!!! I mean… Yeah!!!).
This is not scientific, but it looks like a 10-15% boost when I take out the added clicks.’
I’m not so sure about this. I’ve done a quick survey of a few publishers via IM and they report mixed results this past week. Some are up – but I wonder whether it might be more to do with the change to vary the number of ads they are now showing per ad unit which they explain should lead to an increase in earnings:
‘To increase monetization on your site and improve the relevance of ads, AdSense now varies the number of text ads that appear in a given ad unit. In cases where we determine that increasing the size of the most relevant ads will improve performance, we’ll drop the lowest-performing ad or ads and expand the remaining ones to fill the entire unit. Showing fewer ads works to your advantage, allowing the better-performing ads to draw more user attention and click-throughs. Google AdSense technology will automatically determine the optimal number of ads to display on any page and will only show fewer ads when doing so will make you more money!’
