One metric that can now be relatively easily measured and can help to give you some sort of idea how "important" or "trusted" Google considers your site is to monitor the crawl rate.

There are ways of increasing your crawl rate like for example regularly updating your site, or getting high quality links from other sites.

One site that makes the crawl rate very easy for you to track on an ongoing basis and even lets you compare and rank yourself against other sites is seometer.com.

The site is free to use and its just a matter of submitting your url which gets added to their database, once your site is added you will be given a url like this one which I have set up for this blog, and be able to monitor a graph like the one in the picture below.

It takes a day or two before data is collected.

You can also create a variety of different sized buttons which you can generate on the site and display live crawl stats like in my button below...



Seometer is a valuable addition to any blogger or sites owners toolkit and with its ease of use something that won't take more than a few minutes to get up and running with.
