Google Alerts Hack (via DuctTapeMarketing) – The premise of this is to use Google Alerts to see who is linking to your blog or picks up content you’ve recently published.  Think of it as a hybrid of Google Alerts e-mail alerts and blog pingbacks.  Very easy to implement – (1) Go to Google Alerts (2) in the search box input link:http://www.YourURL.com (replacing YourURL.com with the site you’d like to track) (3) Select the type and frequency. There you’ve got it, an easy way to build a strong community and readership to your site.

Google Insights for Search – Introduced this week, Google Insights provides deeper flexibility and functionality for advertisers and marketers to understand search behavior as well as adding new features like a world heat map to display search volume and regional interest.  Similar to Google Trends, Google Insights allows you to see search patterns over specific time ranges as well as top related and breakout/rising searches across multiple verticals.  This is a great tool for any business and could really give the likes of WordTracker, Hitwise and comScore a run for their money.

Google Advertising Frequency – Because of their acquisition of DoubleClick, Google will soon be able to provide advertisers on the content network the ability to cap the frequency at which a user sees your ad, better reach and improved reporting.  This should be fully implemented in the coming months.
