An optional feature of our WordPress sites is the ability to join our link-share network. This program intends to boost your SEO score by linking to similar sites from your website. These links are located on landing pages automatically generated on your site. The system avoids linking to companies located in your state/province, so you don't link to your direct competition.
By joining the system, other sites can link back to yours, again avoiding direct competition. The idea of the network is that all users in the system help boost each other's SEO scores.
You can join the network for free from the WordPress settings page in IO.
Additionally, if you do not want to link to the sites selected, you can exclude them with a checkbox. The excluded sites will still be in your list if you wish to link back to them in the future. Users are allowed a total of three active outgoing links.
