After you comment on blogs with follow links what the best way to tell Google page has been updated so it can scan your link faster? Ping it? Thank you
Most of the weblogs have ping service installed that can tell the Google or similar site each time the contents are updated. Otherwise you can ping that url intentionally.
You can ping the links you've created and it's supposed to help Google locate your backlinks quickly. However, the best way is to let Google naturally crawl the site and find your links.
