WordPress sites have the ability to add a custom search engine to their site. This document will walk you through the process of creating a Custom Google search engine and adding it to your site.
The process for using Google Custom Search Engine has changed due to a change in the process by Google itself.
- Log into your WordPress site dashboard, and either click the Customize Your Site button or hover your mouse over the Appearance menu on the left and choose Customize.
- In the left menu, click Search Options. In the next screen, click the check box for "Use search on this site." When you have that clicked, you can then enter your Search Engine ID value in the field, and click Save & Publish.
