Google has confirmed that it is looking at integrating SearchWiki directly into pay per click advertising campaigns.
Writing for Search Engine Land, Barry Schwartz said he read reports about possible experiments relating to AdWords results.
He said he emailed Google to ask for some comments on the speculation and received a statement from a spokesperson.
Google said that as part of its ongoing commitment to innovation, it is looking at ways to allow users to customise ads appearing in sponsored links sections.
Using a version of SearchWiki, users can delete ad results from companies using pay per click services.
"This experimental feature is only visible to a small number of users and we have no news to announce at this time regarding developments in our AdWords product offering," Google added.
Google SearchWiki lets users rank, delete or add notes to search results. They can also promote or demote results and add new web pages.
