Google Inc is looking to improve the relevancy of its search results as it tests out a new feature that lets users vote for or against search results, in a way similar to selection process at community content sharing site Digg.

Google Labs, is testing an experimental search function that lets you influence your search experience by adding, moving, and removing search results.

When you search for the same keywords again, you'll continue to see those changes. If you later want to revert your changes, you can undo any modifications you've made, the site says

The search engine giant said only a select few are invited to participate in the test and the experiment may not be available for a few weeks.

So how does it all work?

By clicking on the up arrow next to the result, the link will shift to the top of the page whenever you search again with the same keyword. An orange star will appear next to that result.

If you don't like the result you can click on an x and the result will be hidden if you query the same keyword in the future.

The feature is similar to the popular social news site, Digg, which allows users to determine the position of news articles on the service by choosing to approve the article or not.

By allowing the use of this feature only for individuals, SEO manipulation is avoided. The changes made are visible to only the person that initiated the changes, not to all Google users. The user must be logged into a Google account in order to use this Digg-like feature.
