Today, Rand has a look at how and why it can benefit you to do SEO on someone elses site.
Make sure sites that mention your brand positively rank well
Leverage the domain authority of other sites. Google+, Twitter, Facebook and forums are some examples of domains you can use and have control over a lot of what’s on the your page.
Offering to write a guest post is another way to leverage another site’s domain authority. Don’t necessarily go after a link, just associate your company with it.
Link to pages that mention you on more authoritative domains. Increase the value of those links and reference them as much as possible.
The goal here is to have more control over more of your SEO ‘real estate’.
