Categories for Google My Business pages - do they need to match terms on website?

[Marce521]

I have a chiropractor client with three locations. Because the Chiropractor category is very competitive, whomever originally set-up their GMB pages elected to use the category "Pain Control Clinic" for two locations, and "Medical Center" for the third location. They rank badly for these categories.

Their website does not contain many signals for pain control or medical center; it is very much chiropractor focused. Is this something Google takes into consideration when deciding how to rank GMB pages?

I'm not hugely knowledgeable on GMB, but no I don't think that GMB checks an associated / verified website, and then uses data from within it to sort its own internal GMB listings. I could be wrong, so I'd wait to hear from a couple of others. As far as I know though, GMB rankings are affected by GMB data and wider-web rankings (on Google's main search engine) are affected by a rich mix of data, including open-web data. But GMB rankings, are not (I don't think) affected by open-web data
