Social media sites like Twitter and Facebook can influence search engine optimization (SEO) because links shared on these sites impact search engine rankings. Search engines like Google and Bing also consider the "social authority" or influence of users when determining rankings. Integrating social media with SEO can positively impact the user experience by increasing engagement and blending social and search results. It also allows brands to build awareness, community, and trust through customer service and collaboration on social platforms. Overall, social media and SEO complement each other to improve content discovery and drive qualified traffic and sales.
