Well, according to the major search engine Google, it doesn’t take into consideration social media into account in their algorithms for the SERP rankings. The social media influence is almost negligible for considering for ranking, but the fact they the effect is true as these social media influence viewers to see your content which they find it to be more worthwhile than your competitors.
Users will attach your brand name with the article published thus creating a new keyword which drives users to your account.
The quality content that you publish will be shared by many social media users if that published content creates a connection with it.
The more shares your content gets the more is the SEO score improves and thus higher is the ranking. On this note, I would recommend you join the SEO course from Intellipaat and also watch our YouTube video to help you get started along with the YouTube video on SEO tutorials for beginners.
