Introducing Feed Compare, a free web application that you can use for comparing FeedBurner feeds. This tool is great for checking out your competition and noticing trends in growth.
Much like comparing website ranks using the Alexa website, you can use Feed Compare to compare your feeds against up to three other feeds. All you have to do is input the name of your feed, and then the name of your competitors feeds.
Features for this tool include: viewing up to 24 months worth of data (other options are: 12 months, 6 months, 3 months and one month). Zoom in on particular timeframes using click and drag. Users can link directly to the feed comparisons chart much like Alexa ‘permalink’ style. And it allows users compare up to 4 feeds at a time.
