Easily Find and Link to Related Content with WordPress
Linking to other posts on your site with keyword-rich links is one of the best things you can do for your on-site SEO efforts.
How to Do It
When you have some content in your visual editor, simply highlight whichever word or words you would like to link, and click the link icon.
When you click the link icon, a link dialogue box appears. Simply type your keyword into the search box, and then related content from your site appears below. Click on whichever post you’d like to link to, and everything is filled in automatically. Then simply hit the “Add Link” button.
