Add your keywords and location in the business name e. g., Total Builders Ltd, Conservatories, Ceilings, London. Keyword stuffing is against Google TOS, but they don't care. I talk to live support all the time, and never once have they mentioned any of my clients GMB listings having keywords or location where they shouldn't be. My clients usually rank number 1, or at the very least in 3rd (depending how competitive, and if the competition is also keyword stuffing). Do this and watch that needle move very quickly.
