Eso te beneficia en el sentido de poder mostrar eso a la gente que no sabe sobre ello. Le da valor a tu pagina en los ojos de muchas personas que no saben de ello.
Sin embargo en cuanto a seo no hace mucho...
Te copío una respuesta que me dieron a mi en una pregunta privada utilizando SEOmoz pro. No responde a todo y deja algunas dudas pero te da alguna información interesante. Esta en ingles, es muy larga par ponerme a traducirla. Espero te sirva!
Hi Sebastian,
Thanks for your question!
Having a lot of fan/followers DOES strengthen your brand and sends positive social signals to the search engines when those fans/followers are engaging with your Facebook page/Twitter feed/Google+ page etc. in meaningful ways (e.g., sharing quality content that you post, tagging you in conversations, interacting with each other on your page and posting content on your page.) The type of fan/follower that is going to help your brand cannot be bought. They may not even be a real person, much less a real person who is going to interact with your brand and result in conversions.
I recommend investing your resources in producing engaging content, holding contests, advertising specials, giving away free apps, etc. that users will want to engage with. You can get your content in front of targeted prospects on Twitter with promoted tweets, and on Facebook with paid advertising to build up your community, if you wish. Facebook's advertising program allows you to highly target users, the kind of users who would be interested in becoming potential customers. This may take a bit longer to get your community seeded. In the long run, however, it will worth it. The ROI on building an active social media presence with authentic engagement will far exceed anything that is built on shifting sands. This will send the search engines the social signals that will help you in terms of SEO, and will build your brand and increase conversions (whether that be purchases or other).
Acquiring fake fans/followers, on the other hand can be extremely detrimental to a brand in several ways, beyond the fact that they are a waste of time, money, and effort. Fake followers/fans can put your real community members at risk by hacking into their accounts or spamming them. They can also ruin your reputation in other ways. There are now services such as Fake Follower Check that anyone with a Twitter account can use to see how many fake/inactive followers someone has. Tools aren't needed, though, to sniff out social media "communities" built on a fake fan base. Just look at an account that has 10,000 followers with automated tweets and minimal retweets, @ mentions. Fake. The same goes for a Google+ or Facebook Page with poor content and minimal engagement. Fake. In this day and age, engendering trust is paramount for brands to succeed. Trust is, in fact, how social proof works. People buy from brands they trust. When their friend recommends a brand, that creates trust. When a stranger recommends it, eh, not-so-much trust. But when your brand is exposed for having fake anything (social media campaigns or otherwise), trust is shattered.
Fake followers do not build quality social media communities that have a lot of engagement (with the brand and with fellow community members.) They do not "evangelize" brands. They do not post and share quality content. They do not download your e-book, make videos celebrating your brand, or purchase your products and services. Fake followers usually, well, do nothing. Which means they are not sending social signals to search engines that would help your brand in any way.
Best of luck,
Christy
