Pinging notifies search engines that an update has been made on your blog. A signal is sent to ping servers which will generate a list of blogs that have been updated with new material. Pinging is a very useful tool and should be used to maximize a blog's exposure. Pinging your blog is an excellent source of building link popularity while gaining global exposure to your blog. This will help you get more traffic, more visitors, and listed in the search engines faster. It is not difficult to ping your blog. There are websites that will do it after you enter your information or you can set it up in your blog configuration to have it automatically done. There are numerous free sites that will do it for you. Two of the better ones are: http://www.pingomatic.com/ http://www.pingler.com/ . Basically, all you have to do is enter your blog URL and name. Then, check all of the services that you want to know about your blog. The more the merrier. You can ping your blog manually or automatically. To do it automatically on Blogger through your blog configuration, go to settings and scroll down the page to "let search engines find your blog." Then, use the drop down box to say "yes." Manual pinging is simply going to the above sites and filling out the form. Then, just hit the ping button. Wait for the site to finish pinging your blog before you leave. Refrain from sending excessive pings in a short time period because you could get banned from some search engines.
