Google Webmaster Tools did a recent update and added some new cool features.

Here are some screen shots:

Google Webmaster Tools Keyword Update

Here are the main issues:

1) They are going to be updating the keyword data daily, which is about time.
2) How often on your site Google found a particular keyword.
3) Display of URLs which have the keyword associated.

One benefit from these new add-ons is that you can discover evidence that your site has been hacked if you have “casino” or “viagra” keywords appearing in the list. But mostly, you can use the new data to highly focus on keywords which are “on the edge” of performing well for your site.
