Why to ping blog? In blogging, ping is a push mechanism by which a weblog notifies a server that it’s content has been created or updated. It notifies different feed sites and search engines that your blog has been updated which helps them to make changes in their search engines and feed algorithms. Hence the main purpose of doing this is quick updated indexing of your blog on search engines. Don’t ping your blog again and again. If you are using WordPress then there is no need to ping , WordPress blogs have auto ping mechanism which works whenever you post or update.
