Google has updated its Google Trends site which will show the most popular searches of the day. The tool will shows the peak search time, related searches and blog posts. Barry Schwartz over at Search Engine Land has an in-depth look at the new feature.

Janet Meiners has uncovered a new keyword research tool called Keywordtopia.  It gathers keywords from multiple sources including WordTracker, Keyword Discovery, the Google Keyword Tool and of course, Yahoo!'s Search Term Suggestion Tool.

There are a couple of other neat features that make this one stand out.  One is it automatically searches other sources for complimentary keywords that the above tools don't turn up.  The other time-saving feature is that it organizes the keywords it finds into logical groups so you can import them easier into Ad Groups in Google AdWords.  Learn more about the tool at Keywordtopia.com.
