Adding services to primary category vs secondary category

[cfazio]

I am adding some services to one of my healthcare clinic GMB - just beefed up the website to reflect what they actually provide, so matching GMB services.

Had me thinking... is there any difference in adding services to the primary category, vs secondary categories?

For example: primary is "medical clinic" secondary is "doctor, medical center, wellness center, family practice physician, general practitioner".

Should I be adding specialties to the category that makes most sense (we offer a wide range), or does it have more 'weight' to add it to the primary category?

More generally ... do services even have an effect on ranking? Some say they do ... some say they do not ... at the very least it could improve CTR.

Thanks for the advice!

The primary category contributes more to ranking than secondary categories - so choose whatever is most important to your business.

Services don't impact ranking but I would still add them because they can get you justifications.
