google are now enforcing the one unique phone number per listing. Simple if your business is like a local coffee shop, googles noddy business model. (Oh soory its all about Locations, I do not know of a Location with doosh) If you are a family with individual businesses, multi-business entrepreneur, or a multi-business location then you need to consider what you are doing.
google still greedily scrape every scrap of information they can find off the Web and then try to merge it all together in Maps listings. This merging is to give the searchers a 'quality experience', however googles algorithms are not that good.
Web listings you set up 'a priori' are there ready to be scraped by google. Do they satisfy these criteria in being identical to what you have typed in so far and appear to be 'unique':
Business Name/Title is your Legal/Trading Name:
Is this name unique at your location or in your vicinity as far as you can make it?
Having your family name on different listings will likely trigger a 'Search merge'.
Are there nearby businesses with the same non category words in their Title or even address? I have seen an address including 'Lodge' generate a 'Holiday Apartment' category. (google are not good at proper IT) A good reason not to put locations in a business name, to minimise 'Search merge'.
Address is in googles format and any Maps red Pin is the same position as googles.
If there are Web listings with separate Pins you are likely to get pesky duplicates created.
If there are several businesses, each with its own Phone no, at the location add a Suite No, Unit No or ABC House at the start of address line 2.
To reduce duplicate problems only put one Phone No in your listing.
The 'Legal Bit': This advice is built on sand.
