My client is in a very competitive market, since we cannot rank for the large city name, I was thinking of trying to rank for 2 surrounding neighborhoods. He gets a handful of leads per month based on proximity, but I think he could get more calls/leads. I'm wondering the best way to tackle this. Do I take the Large competitive city page linked to his GBP and add 2 paragraphs to that page, 1 for Neighborhood A and 1 for Neighborhood B? Or, do I have a sub-page for each neighborhood, e.g., site.com/big-city/neighborhood?
