I hear from some SEO professionals that whenever you you comment on blog,website or forum then copy that URL and ping it or submit it to google,It is necessary if yes then what is the best method ping or submit to google.I really need help,a helpful answer will be appreciated
The links you submit to forums or blogs 99% of the time are marked as nofollow, which means google does not care AT ALL about those links. So I recommend you don’t bother wasting your time since nothing will happen of it.
