According to a white paper on RSS (pdf) sponsored by Yahoo and Ipsos Insight, providing easy ways for users to subscribe to RSS feeds using their favoriate feed reader or aggregator can improve distribution of that feed.
Thomas, our SEO Designer and blog marketing guru, has made a very cool tool for quickly creating up to 14 RSS feed subscription buttons or chicklets for your blog.
Just fill in the blog title, blog url and feed url and the for will reply with code for subscription buttons to: Rojo, My Yahoo, Bloglines, newsgator, My MSN, Pluck, NewsBurst, searchfox, Google Reader, My AOL, del.icio.us, Feedster, Furl and Yahoo My web.
I must say, it is a very useful tool!
[Update: Thomas has added even more subscription buttons as well as bookmarking tools.]
