When would this be useful? If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user-added links ensures that you're not giving your page's hard-earned reputation to a spammy site.
Thanks Brian. I’ve had a “a-ha” moment thanks to you! Great advice. I knew that backlinks would improve the organic SEO rankings to our client-targeted landing pages but I never knew it was through getting influencers to backlink blogs. I always just assumed it was great content that users wanted to share with others. It was driving me mad why people love my content but never share enough. Now I know!
Another way to increase traffic to your website is to get listed in free online directories and review sites. For most of these sites, your profile will have a link to your website, so actively updating these listings and getting positive reviews is likely to result in more website traffic. In addition, many directories like Yelp have strong domain authority on Google. There’s a chance that your business’s free Yelp page could rank high for relevant searches.
