MillionRSS is not only a RSS Feed Directory, but it aims to be the largest on the Internet. As I type this they are currently indexing 178,374 RSS Feeds! It doesn’t seem to be doing to badly in Google either as I’ve noticed it has been providing me with some good link juice. You can submit your feed for free and it only takes a minute…so don’t be lazy! They kindly even have a SEO Blogs category, and a category for just about everything under the sun.
What we do: millionRSS is a project to collect over 1,000,000 RSS feeds that are out there in the wild west of what we know as ‘the blogosphere’. We offer free submission for anyone to easily send us their RSS feed details (along with their site description and branding information). In turn, we will syndicate your feed for our readers and will give you a permanent link from our site. That’s it, pretty simple.
