I don’t see how Yahoo Pipes does anything that makes normal php blog post urls into RSS feeds.
RSS Bot is still a manual tool since it resides on your desktop, doesn’t create RSS feeds out of individual content pieces and auto submit them.
While RSS bot is good value, it doesn’t address the missing element for many people’s RSS submissions process, which is that most people aren’t submitting ind. posts and content as individual feeds THEN auto submitting.
Yahoo Pipes is a centralized aggregator of all your feeds, it seems, and it is still in BETA, and again, I don’t see how it constantly scans your sites for newly published content, nor do I see how it auto-submits and creates feeds for individual posts.
I like what Yahoo Pipes is capable of, because you can submit RSS feeds for all your social profiles as well using their software.
but again…
one time submissions for main profiles is great, and good basic SEO practice, but taking things to a whole new level means doing what I keep mentioning, individual content pieces submitted as their own unique feeds.
Automatically…. nothing manual required…
