First, Compete is a site where you can see metrics from the million largest Web sites. Sorta like Alexa, but different.

Here’s how to use it. First, let’s look at traffic of Techcrunch.com. Yowza, Mike is up, way up!

Now, the new features: Attention. That shows how often people click on TechCrunch and how long they stick around. Clicks are up, average stay is down (Click on Engagement and select attention).

Finally, click on “Growth” and select “Velocity.” This shows you how fast traffic is going up, or down.

Oh, and you can compare big sites to each other. Here’s TechCrunch compared with CNET’s News.com compared with Om Malik’s GigaOm.

How does your site compare?
