I have 3 ways you can derive SEO value from your time spent on social networking sites:

1. Linking between profiles, can give you the chance to connect with your target audience on more than one platform, increasing the amount of

touch points your brand has in their online lives.

2. Promote your content,Content marketing forms the backbone of your SEO and drives most of your online marketing tactics in general.

3. Customize and optimize profiles.Social profiles can rank in the search engines like any other webpage.
