Google Tops Feed Reader and Social Bookmark Rankings

These rankings are based on how many times people across the Web add a link to a bookmarking service or a feed to an RSS reader using the AddThis button. (That’s the little orange button with the gold cross you see below each post that lets you bookmark to whatever service you happen to use. Tens of thousands of Websites have incorporated the AddThis button—including Time.com, ABCnews.com, and LonelyPlanet.com—and people use it nearly 2 million times a month to add feeds and links to various services). On the feed reader side, according to this sample of data, Google comes out on top with 37.7 percent of activity, versus 20.7 percent for MyYahoo, and 9.7 percent for Bloglines. Remember, these numbers don’t mean that there are more people who read their RSS feeds via Google Reader than via MyYahoo. It just means that people are adding more feeds to Google Reader. On the bookmarking side, in September Google commanded a 17.0 percent share of all Web bookmarking activity, followed by native-browser bookmarking (i.e., “Favorites”) with a 16.1 percent share. Yahoo’s Delicious dropped to third place with a 9.2 percent share, and Facebook came out of nowhere to claim the fourth spot with a 7.1 percent share (beating out Windows Live, Digg, MyWeb, Furl, StumbleUpon, Ask, and Reddit). Again, what this measures is how many times someone actually added a bookmark to one of these services, not how many total subscribers each service has.
