Social media optimization is a set of methods to attract users to content through a website promoting them via the social media.
We have to note that it is a thriving practice for Internet users and companies which is increasing. The question is how Google sees the links from social networks like Facebook and Twitter.
Links from sites like Facebook and Twitter are treated the same as links from any site.
That is, they can transfer the PageRank (if not using nofollow) and can therefore bring popularity to your website. This is good news for the optimization based on social networks.
However, many Facebook profiles are private, and therefore the robot can not follow the links, again, Twitter uses nofollow. We recommend to create a public page for Google and not block links to get your netlinking benefits.
Now that you know that it is time to optimize your netlinking through social networks.
