Definition: Social signals refer to a webpage's collective shares, likes and overall social media visibility as perceived by
search engines. These activities contribute to a page's organic search ranking and are seen as another form of citation, similar to backlinks.
Social media is now more than a messaging and acquisition channel: it directly impacts an online store's SEO. This makes it more important than ever for ecommerce operations to build a cohesive social media strategy that focuses on promoting high-value campaigns, sales and products.
Social signals and SEO - A search engine's chief aim is to provide high-quality, relevant content to users. Search engines gauge quality in large part by how frequently a URL is seen throughout the web, and as more web communication has moved to social media, Google and other search providers have integrated social signals as a ranking signal.
Social signal is a measure of social media activity, such as a vote, share, or other engagement that a search engine might take into consideration as part of its ranking algorithms.
