What are social signals, and why are they an increasingly important SEO factor
Social signals are the likes, shares, votes, pins, or views people place on Facebook, Twitter, LinkedIn or other social media sites that filter out to the various search engines.
A search engine's primary aim is to provide high-quality, relevant content to searchers. Search engines, such as Google, judge quality in large part by how frequently a URL is seen throughout the internet, and as more web communication has moved to social media, Google and other search providers have integrated social signals as a ranking signal.
