If you’re interested in tracking the performance of your blog you might like to start using UrlTrends – a tool that checks page rank in Google and Alexa as well as tracking the incoming links to your site.
It looks like a useful tool – although when you first use it the information might not be that dynamic as its not likely to have been tracking your performance previously. Your first checking of your blog will simply add you to their database and show you graphs with just your current performance. However if you come back over time you should see it tracking your performance.
I also use a free keyword tracker over at Digital Point which also tracks a number of key performance indicators for your site or blog. It Not only tracks your page rank and incoming links, but also checks how you rank on keywords in Google, Yahoo and MSN as well as telling you how many of your pages have been indexed in the search engines.
The only down side of this tracker is that you really need to use it regularly in order to get the best out of it as it only checks the above features for you when you manually stop by and ask it to. I do this as a part of my daily blogging rhythm.
Another useful tool on a similar theme is TrendMapper; again, this will become more useful over time as the data builds up.
I enjoy using DP kw tracker tool
