I just finished integrating some Google tools with my website. This was mostly a chance for me to play around with a few new services and see how they work.
First, I added an advertising bar from Google AdWords. Advertising drives most of the innovation on the internet today, but somehow I doubt much of that money will make its way to me. Still, I get a kick out of seeing what Google thinks of my website by looking at the ads it chooses.
Next, I added visitor tracking from Google Analytics. This is a service that allows website authors to learn more about the people who visit and how they interact with the website. It shows me how many visitors I've had, where they come from in the world, how they found me, and lots more.
Finally, I used the Google AJAX Feed API to add a News section to my website. On that page, I'm displaying my Google Reader shared feed. Now, whenever I read something interesting with Google Reader, I can just click "Share" and that post will show up on my news page. How cool is that?
