If you’re not satisfied with the stats FeedBurner is giving you, then the Feed Analysis v1.0 from Blog Perfume is just what you’re looking for. The Analyzer takes the information from your FeedBuner feed and turns it into nice easy to read charts and graphs. It also comes with a few prediction tools that will tell you your blog’s worth and how many subscribers you can expect to have in the future. I think the prediction tools are a little off.
Using Feed Analysis is very simple. Login to your FeedBurner Account and choose your feed. Download your FeedBurner stats as a CSV file and then upload it to the Feed Analysis. Within a few seconds the Feed Analysis will give you some very interest information.
