In recent years, online marketing strategy has metamorphosed with the growth and relevance of social media. Many companies have turned to Facebook and Twitter with high hopes of drawing in legions of dedicated consumers. Unfortunately, the "build it and they will come" mentality doesn't reach it's aspirations.
While marketers understand that social media is an important source of qualified traffic that can help companies to build and maintain visibility on the web, it can be difficult to assess just how much social media affects SEO ranking.
Google has acknowledged that spiders can crawl social media pages, however, there is no definitive proof that social signals (likes, followers, shares) cause companies to rank higher on SERPs. Despite this, SEO professionals argue that these numbers have an influence, as they are indicative of your company's reputation and they act as a gauge of your ability to build credibility online.
