Google is testing a new search feature which allows you to promote up search results you like and completely nuke the ones you don’t.
Here’s how Google describes the experiment:
This experiment 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. Note that this is an experimental feature and may be available for only a few weeks.
And here’s how it looks in practice:
Before you rush off to push all of your–or your clients’ web sites–to the top of Google, know this: the changes currently only apply to your personal search results.(via)
