That’s a good question, it’s the biggest confusion for most people.
Actually, most of the organizations have a problem using their brand name in all those things by which they made their authority on Google.
Not only for WordPress, but all the brands also have guidelines or terms and conditions that a community is not authorized to use their brand name in any SEO factor and if want to use in name can use as postfix like “Plugin for wp”.
The guidelines of WordPress are like-
- Plugins may not use vulgarities in the name or slug.
- Plugins may not use WordPress or Plugin in their slugs except under extreme situations.
- Plugins may not use version numbers in plugin slugs.
- Due to system limitations, only English letters and Arabic numbers are permitted in the slug.
