Bucking a trend, Yahoo is encouraging content providers to provide detailed metadata for each page. Most of the major search engines have recently spurned metadata as a reliable source of content information.

Participants in the CAP program are subject to a regular review process with both automated components and input from Yahoo's editorial team. Cadogan says a key benefit of program participation is feedback from these quality reviews, though he won't say exactly what type of feedback will be offered, nor whether favorably reviewed sites get a ranking boost.

Pages that don't meet Yahoo's standards will be given the opportunity to improve or risk potential rank demotion.
