For the last several months Yahoo has been working hard to prepare for the release of its new publisher network that will release tommorrow for bloggers and small publishing networks. A "source of a source" has informed me that Yahoo will be releasing its Publisher Network tommorrow and will include an array of different features that sets itself apart from Google's service, namely strange odd looking unrelated ads (see top of website) and editorial review for selection of ads on content pages. This could mean good things for publishers that decide to use Yahoo's new service.
Some of the main differences between the Google product and what Yahoo is offering is that Yahoo is actively going after the growing online medium of blogs. Of which Search Engine Roundtable is a perfect example (see ads at top of website). Yahoo is looking to possibly challenge Google's pricing power as well by spliting the fees from clicks generated on ads from a website. They are also boosting editorial review and placement of relevant ads on publishing sites. Where as Google relies on technology to do the job. Will it be enough to make bloggers switch?
