Social signals refer to the interactions and engagements that occur on social media platforms, such as likes, shares, comments, and follows. These signals indicate how users perceive and respond to content, helping to gauge its popularity and relevance. Search engines like Google may consider social signals as a factor in ranking web pages. While not a direct ranking factor, high levels of engagement on social media can lead to increased visibility and traffic, potentially influencing a website's overall performance in search results.
