GBP Custom Services: How Many Keyword Variations Are Worth Adding?

[Jessica C]

I am updating services on a GBP and wanted to ask the community what the current recommendation is for adding keyword variations- and what to do if you have multiple variations that you know through extensive analysis that customers actually use? Does adding all of they variations help with ranking the GBP?

example: if the business offers maternity photography, should you add:

maternity photographer
maternity photography
maternity photos
maternity pics
maternity pictures
maternity portraits
maternity photoshoot

pregnancy photographer
pregnancy photography
pregnancy photos
pregnancy pics
pregnancy pictures
pregnancy portraits
pregnancy photoshoot

outdoor maternity photographer
outdoor maternity photography

outdoor maternity portraits

studio maternity photographer
