Social signals are human interaction metrics on social platforms like Facebook, Twitter, LinkedIn, Reddit, Medium, etc. Some examples of social signals are: likes, dislikes, shares, votes, pins, views, etc. which commonly help to showcase popularity and affinity for a specific piece of content.
While social media doesn’t directly affect your Google ranking, social sharing does directly increase the visibility of your page. That increased visibility means it may get noticed by a creator of content, such as a blogger, journalist, or an author. That creator may mention it in a subsequent piece of content and if they linked to it, that page is then more likely to rank well.
Therefore, it’s the combination of good branding and a strong social media presence that will make the difference here. Good engagement, and of course good content, will make your results more relevant to others. So, make sure you link your social media to your website and vice versa.
Always include your social media signals, on your website so that people can easily connect with you and stay connected.
