Social signals: what are they today and how useful are they to SEO?
For at least ten years we have been discussing social signals for the SEO, and to be precise we try to understand whether the so-called social signals (generally understood as number of followers and interactions on various platforms) have a direct correlation to the ranking of the site and whether, therefore, they are a factor that can influence a website’s visibility in search results. Despite the denials and clarifications of Google, this theory still keeps popping up, and actually might have some truth to it: to put it more simply, the authority gained on social might actually give a positive boost to the site on Google, as long as one does not consider SEO social signals as a direct ranking factor, but as one of the many “external” elements that help strengthen the online brand.
