Social media can help with SEO by allowing you to build links through outreach on platforms like Twitter. While social media will not directly help rankings, it provides opportunities to find sites to outreach to for links. When starting out, it's best to scale back outreach and focus on building long-term assets over time by identifying influencers and opportunities for links through tools like RowFeeder, Export.ly, and FollowerWonk. The tone of outreach should be identified and incentives found to make requests more appealing.
