Two updates from SEOmeter.com:

Website submission page has been added. We decided to charge an annual (but modest) fee for each submitted site for monitoring. The reason behind introducing the annual fee is to support the cost of our server and database resources which will increase over time as more sites are monitored by us.

The other update is, an AJAX comparison menu was added in the site information page (see the screenshot below). You can enter two more urls in the comparison form to compare the current website against two other sites in terms of crawling history.

Currently there is one known issue with the AJAX comparison form. For whatever reason, AJAX refuses to retrieve results on any mod-rewrited page. So for example, the comparison form works fine on http://www.seometer.com/index.php?search=google.com, but not on page http://www.seometer.com/cache/google.com . We are working on fixing this issue. The issue was fixed.
