If you're an iGoogle user, there's a new gadget that could be of great value. Insights for Search displays the top rising searches in the last seven days. After adding the gadget you can edit the settings - by results type (rising or top searches), search type (Web, Image, News or Product), search term, location, category, time range and set the max number of results.
I find great value in customized start pages like iGoogle and this gives me one more reason to like them. It's an excellent way to get a snapshot of what users are searching in your industry by simply launching your browser. Click on one of the terms from your list and you get to a Google Insights page that displays more detailed results and the ability to dig deeper with resources like location-based heat maps, news headlines, more search data and segmentation abilities.
Below is a shot of the gadget. This unfiltered list shows the G20 Summit as the fastest rising search worldwide on Google over the past week, followed by the feared Conficker bug, which is followed immediately by McAfee - no small coincidence.
