Matt Cutts reports on Searchology 2009 content and gives tidbits about Google that you may not have been aware of before.
Google Search Options. Referred to as a handy “toolbelt” by Marissa Mayer. This feature allows you to have a customization option to filter your search results. Simply click on “Show options…” link and then choose from the available links, such as related searches, wonder wheel, and sort by time, to filter your results displayed.
Google Squared. This Google Lab is said to be scheduled to launch later this month. You can type a search query and Google tries to build a “square” that can be saved. The example Matt Cutts gives is with the query “small dogs”. If that is what you search, Google will returns types of small dogs, along with a few facts about each type. You can customize your square by adding rows for the different types, along with new columns (i.e. “energy level”). Google will try to pull facts from across the web to fill in your requested square data.
