If you’re trying to drive traffic to your site, you know the value of monitoring your site’s search engine rankings, but the task can be time consuming. UrlTrends provides insight into the most important trends at a glance. Enter a Url and UrlTrends displays your Google PageRank, Alexa Rank, and link popularity trends (the number of incoming links) for Google, Yahoo, and MSN, as well as information for social bookmarking sites Furl and Del.icio.us. Results are displayed in graphs (like the one pictured above). You can also add a PageRank button to your site.

UrlTrends offers a variety of plans, from a free Basic Plan that lets you monitor up to 10 Urls (watchable via RSS or email), to heavy duty plans at up to $800 per month, and a range of plans in between.
