We have a team of 10 doing around 100 forum postings per resource in various forms. We are getting backlinks as expected. But wondering if we need to stop forum postings after 100-150 forum postings per forum. Because... when we were talking to an experienced SEO leader other day he explained that google might give you maximum 3 backlinks per forum. So it really does not matter if you have 100 forum postings or 500 forum postings. Your backlinks will not increase from 3 in google. Is this true? If yes we are wasting our resources by posting more than 500 posts? Experts please advise..
