Auto Blog automatically posts content from RSS feeds your blog, it’s like feedpress or wp-o-matic, except that it actually works, brilliantly and simply! This is the way to automatically post content from multiple different RSS feeds to your blog(s). You’ve probably struggled with alternatives like FeedWordPress, WP-o-Matic, Yaab autoblogger or even autoblogged… and if you haven’t yet, then don’t worry, because we can tell you now that they don’t come close to AutoBlog… which just plain works. No coding required, no complicated instructions, no worries!
