Here is LIKE the situation I am talking about. In the Capital District of NY State 'Albany' is the hub. But, 20 minutes east is Rensselaer County with "Troy" as it's hub city and to the west is Schenectady County with the City of Schenectady as it's hub. That's the triangulation here, but, not unique to here ...and we encounter this situation coast to coast ( we have clients coast to coast ). So, as mentioned, I'm using my 'hometown' as an example, because I am most familiar with this locale, but, this applies in other areas too ... an example, Baltimore Maryland and it's suburbs. Oklahoma City, OK and it's suburbs etc. etc.
In the Capital District of NY State the overall population is 1,000,000. 1mm people and 5 Honda Dealerships all sharing that market. So even though 1 Honda Dealership is in Troy (Rensselaer) and 1 Honda Dealership is in Schenectady and 1 Honda Dealership is in Albany, they are all close enough together that they all sell cars to people who live and work in the competitors market. 20 Minutes apart at the points of the triangle more or less.
MY client is an outlier. It's GMB address and physical location is "Latham" NY. Not Albany Schenectady or Troy. Another outlier that falls in the into the same scenario is Saratoga Honda. They are a bit north ... but very competitive and the same marketplace / same customer demographics. Clifton Park has a lot of buyers - nearer to Saratoga ...but no dealership is there. Now our area is big enough and Honda is a big enough brand, that I am just talking about HONDA in the "Greater Capital District" as an example, but, you could do the same thing with Nissan, or Toyota, or Ford, or GMC ....etc.
So, I am being 'specific' with my example, but it applies more generally. Now in your reply it seems you may have thought I was talking about USED car dealerships. Yes, in any area this size they are a dime a dozen and we don't represent too many used car dealerships. We are too pricey and they don't have the budgets for us. So, even though we are not, as a place of business, rooftop, address representing a client with the best advantage point, we are 'good enough' that we can rank our client ... not IN the Albany or Schenectady or Troy location, but, in the Local Pac 2 or 3 in any of those areas ... cuz ...we're good.
Good discussion ... but gotta run now. The first night of Chanukah, my wife is Jewish ... shalom.
