SEO Roundtable: Google Blogsearch Ping Going Away, Not That Anyone Used It. “Google announced on Google+ and John Mueller also added to it that Google is going to shutting down Google Blogsearch ‘Ping’ service. It launched back in 2006 when a lot of blogging platforms used the ping method to communicate ‘trackbacks’ i.e. link notifications from one blog post to another. Most of you probably have no clue what trackbacks are and if you do, you are probably thinking, wow – a blast from the past.” I think I just added this to make myself feel old, because heaven knows that Ping has not been relevant for years.
