Now that you know a few reasons why, let's look at a few ways you can build links to your social profiles.
Website Links to Social Profiles
If you don't already, you should definitely link to your main social profiles from your website. There are tons of different ways to do it:
Simple text links in author bios on your blog.
Links using small social icons in the header, footer, or sidebar of your website.
Official follow, like, circle, and connect badges (not necessarily great from the link building aspect, but makes it easier for people to follow you).
Not only will these help increase your social following, they will create official links connecting your main online platform to your social networks.
Also, don't forget about other opportunities to link to your social profiles, such as in author bios on sites you contribute to, forums that ask for your social profile usernames, local review sites that have the option to add your social profiles, and pretty much any other chance you get to link to your social profiles.
