I tried YPN ads and find the ads vaguely related. While adsense gives context related ads. Whats ur observation ? However the per click amount if higher than adsense.
Not really, it all depends on what content you're targetting. I, however, am I firm believable thay Yahoo! is working on making ads content related like Adsense does.
I see some from both sides...it depends on what your website is...Yahoo does ad targeting, but they don't hit every single category..
When I tested YPN, which was a while back, the problem wasn't with getting the right ads but rather with inventory. Their inventory was pretty slim. I guess it should be better now.
