Social Media Optimization
SMO or Social Media Optimization is simply using social media as a platform to encourage traffic.
Various sites like Facebook and twitter have boomed as of recently and by using their popularity as a stepping stone we push our site to other people.
It can be used to raise awareness about a product, problem or even just gather a community. If your content is interesting enough there are surely hoards and hoards of people on social media waiting to lap it up.

This can be done side by side while doing SEM or SEO and it will still act as a great booster to your existing plan.
