WordPress is having great setting for SEO purpose but many wordpress blogger did not know about that feature. WordPress has feature called update services. This service will ping when your blog is updated with new post or article.
Use WordPress Update Services for better SEO
This feature is very useful to reach the internet user faster than major search engine. WordPress provide the default http://rpc.pingomatic.com/ service to ping or update the content. Pingomatic is very power server for your wordpress blog.
For changing the Update services, Login to Admin panel. Go to Settings->Writing->Update Services section from using admin panel . When you see that text box you will only http://rpc.pingomatic.com/ link over there.
My advise to you is when you have good amount content in your blog or website then only use the multiple ping back services.
I used the following services in Update services option.
