It's only been a year since they did their first evaluation, but they're already back with more. The Consumer Reports WebWatch team has released another study that examines how the major search engines disclose paid search advertising to their users.

According to the findings:

• most major search engines are still doing a poor job of making clear differentiations between natural and paid search results
• paid inclusion is not satisfactorily disclosed by any of the examined search engines
• disclosure headings have gotten smaller and more faint on most of the major search sites
• disclosure pages that provide information on what makes up paid search listings are getting harder to find

As for how the search engines fared in the findings:

• companies like Ask Jeeves, Alta Vista, Netscape and Yahoo! were found to have made paid listings more ambiguous
• companies like CNet and MSN Search were found to have improved their disclosure
• Google, AOL Search, Lycos and others ranked about the same as they did in the last test
