For those with WordPress sites that still show the “”Just Another WordPress Site”in their title…
There’s no reason to have “Just Another WordPress Site” in your web site’s Title. Yet Google reports about 657,000,000 such pages. I have no idea how many of them there really are, but you see them all the time. Don’t be one that does that.
Login to WP, click on Settings > General on left side.
On the settings page, there should be something towards the top called Tagline. That’s where you’ll find the Just another WP Site text. If you delete that and save, it should remove from any parts of the site.
