Search engines look for new content and, hopefully, will find your content. You can help them find your content by telling them when you have a new post. How do you announce your post? You send a ping.
Very simply stated a ping is an electronic message to a pinging service that says, “Hey, I have new content!” The big search engines [like Google] and blog directories [like Technorati] have pinging services to keep their content fresh.
You can use a service like Ping-o-matic to promote a blog post or article. WordPress has a great feature that will do the work for you. I’m all about somebody doing the work for me.
