Well I am definitely getting a visitor boost by using social media. Basically I am promoting my website in Twitter, Google Plus and Youtube to get more visitors. How does it affect your website?
Provide or get advice on everything SEO, ask questions, gain confirmation or just become apart of a friendly, like minded community who love SEO and Online Marketing.
It's all about balance.Is it worth it though? You say it can increase your traffic but do you think it's worth spending weeks and months building a profile for the amount of traffic you get Vida? Keep in mind that weeks and months of working on your own site instead would have increased natural search traffic too and now that won't happen since you didn't spend the time creating content.
