This question was submitted to my community forum.
Details: “ Two practices closed/merged after they bought their new Practice right down the street. We already have a google my business profile for the newly opened Practice. What should I do with the 2 old listings? So that I don’t lose any reviews.“
You can only merge profiles if they are in the same location and with similar business names.
However, there is a solution! You will need to contact Google Support to mark the old profiles “moved” and transfer reviews to new Google My Business profile.
Check this tutorial guide for the full instructions:
Hope it helps.
