A free alert service kicks off with two alerts related to Google AdWords and AdSense. You can get daily email alerts with the costs of the expensive AdWords both by bid and by cost per day (not necessarily the most expensive, since Google doesn't report that. Instead, you get terms checked and found to be fairly pricey). There's also an alert by keyword service that emails you when new advertisers appear for a keyword you supply. Assuming you don't mind a flurry of email when tracking popular categories, this can be handy.
