It’s a one-time fee believe it or not!
The RSS feeds in the SERPs usually end up going away after a while, unless it’s ranking well for low-competition long-tail keywords.
What I’ve seen so far is that they’ll stick around anywhere from 3 hours to months, all depending on the competitive of the term and your blog post title.
Right now, I am experiencing some issues with the cron jobs and the feature that posts all existing posts for you on a scheduled basis.
I also see some errors in log files and want to know what happens if I update a blog post, does that submit again to the RSS Aggregators?
I have a ticket in to these people now about those questions.
Using this software to get 20 or so RSS backlinks per post is going to give your sites’ extreme link juice and you’ll rank with ease for anything new you put out (within reason) because…
1- 20 backlinks to every page on site means deep linking and nice link juice building up
2- Which makes it easier for new posts to rank well (due to SEO weight of your site)
3- Add to that 20 new backlinks per post automatically and you got a winner
IF the scheduling works, then I will be ecstatic with this software.
Even if it doesn’t work for existing posts, it’s still pretty useful for new sites
