While social media signals aren't a direct ranking factor, they indirectly affect domain authority. Highly shared content gets more visibility, backlinks, and brand mentions. Promote your content across relevant social platforms, use hashtags, and engage with followers. Encourage sharing by embedding social buttons. Collaborate with influencers to amplify your reach. Viral or widely-shared content can attract organic links, which boost domain authority. Consistent engagement across platforms strengthens your online presence and authority.
