The role of social media and external links
Although social media content does not directly affect search rankings, social signals and external links (i.e. backlinks) play a crucial role in SEO. External links can help increase the authority of a website, while social media campaigns can indirectly affect search rankings by bringing more exposure to a business.
How to utilize social media and external links?
Create shareable content
Produce interesting, useful or interactive content that encourages users to share it. Social media sharing will increase the exposure of the content, which in turn will bring more backlinks
