Web Search History Tool by Google

Google has more deeply integrated its Web search history product into the mobile version of its search home page. Users in the U.S. who are accessing Google from a compatible mobile phone will see a new history option on the bottom of the page that takes them to a mobile-friendly version of their last 10 searches, along with what time they were queried and from what device. Additional results can then be loaded in 15 at a time.

To use the new listing, which is simply an optimized version of the Web history product that's been around since early 2007, users first have to opt in. After that, it begins tracking searches from any computer or mobile phone where you're signed in.

Besides a listing of all your history, the mobile version of search history also lets you browse through result pages that have been starred. This is something you can do on either the mobile phone or on a normal browser since early March, when Google dumped its SearchWiki project in favor of a more traditional bookmarking system.
