30% of A-list Bloggers Use Adsense

As part of our AdsOnBlogs 500 analysis, we looked at types of income stream. It wasn't an easy task pinning down every type of ad program or donation button from observation alone, but we believe that the figures below are a pretty accurate reflection of what's going on within the top 500 blogs.

I guess the big surprise from these figures was that 35% of blogs appeared to have no revenue capability at all. Whilst no quantitive anlaysis was done on this, it was apparent that the blogs within this category could be divided between those which are simply labours of love and those utilised as PR tools.

The dominance of Adsense is to be expected, but will that remain so with the advent of competing formats from MSN and Yahoo? Adsense seem so far ahead in the contextual field it's difficult to see them being surpassed anytime soon, but who knows.
