Create a link building strategy where you are targeting quality and natural links from other sites that can give your site and articles a higher reputation.
In your website, link a specific article to its category.
Request a link back to your website from the associations or groups that you are a member of. The same applies if you receive a certification. Additionally, link to where you are mentioned in their site.
