In an effort to compete with Google's "Adsense" publisher network, Yahoo has extended the reach of its own publisher network. They will no allow small to medium sized websites access to their publisher network by allowing them to engage in content match advertising for the mega-search portal. Yahoo officially announced this offering earlier today.
Up until now, small web publishers could not gain access to Yahoo's content match advertising. The traffic threshold was simply too high. Now that the threshold has been lowered, it will be interesting to see which of the two advertisers will offer a relatively higher effective CPM. Chances are that it will depend on the subject/theme of the content.
Yahoo says that the system will be linked into the same advertising network, content and applications used by the existing large accounts. However, the self-serve nature of the service means that keywords and landing pages won't be checked by hand. For now, this service is only available in the US.
