By default, WP Engine creates a sub-domain when you install a new WordPress website.
Unless you have a high profile website that needs to be hidden during development, most developers tend to just develop on that site.
But when you are ready to go live, you need to take the following steps to ensure your website is setup correctly.
Add a New Primary Domain
Log into WP Engine. In the install, click on Domains link.
What you will see by default is the wp engine subdomain as your primary and only domain.
Click on ADD NEW DOMAIN
In the pop-up, add the non www as your primary domain and add www as a Redirect From. This may vary depending on your individual setup but for most domains the non www version is their primary domain.
If you have followed the steps above, your domain setup will look like this:
Update WP Site URL & Blog URL
Log into WP Admin > Settings and update the Site URL and Blog Url from yoursite.wpengine.com to your primary domain (localproz.biz).
Update CNAME or A record
Update your CNAME / A records at this point and make the website live.
Redirect WP Engine Subdomain to Your Primary Domain
Once you have your live domain working, there is one more thing to do. At this point, you are losing SEO juice due to having the extra / duplicate subdomain (localproz.wpengine.com).
To fix that, in WP Engine, click on the Edit link next to the subdomain.
In the pop-up, click on the Redirect to dropdown and select the primary domain (localproz.biz), and then click save.
If you followed this guide well, your domain setup should look like the screen below.
And that is how to properly setup your domain in WP Engine.
