Blog Business World has compiled a good list of “Blog ping services: Free and paid” that’s worth a read.
Pinging is really quite simple. It’s letting the search engines, RSS feeds, and other interested blog sites know that your blog has been updated. It’s like running out into the streets of the internet and screaming that your blog has a a brilliant new post for everyone to read.
Well, maybe not quite that dramatic, but you get the idea. It’s simply a notification of a post. That sounds less interesting than the screaming wildly in the streets analogy though. We’ll go with that one.
Many people ask me if it’s essential to ping the blog services immediately after poting as I suggest in the introduction. As soon as you post is the best time. If you do forget, however, ping the blog later when you think of it. Don’t worry about being on time. Better a late ping than no ping at all.
