Adding a link to existing pages, products or posts couldn’t be easier in WordPress.
Select the text you want to create the link with, then click the chain icon (Insert/edit link).
Expand the ‘Or link to existing content’ section by clicking on the text.
Rather than having to type out the URL or look for it in another window, use the Search box or scroll to review all existing content.
Once you have chosen your option by clicking on it, the URL and Title will be populated automatically for you. Simply then click the Add Link button to create your hyperlink.
