i currently have a very well established business. number 1 in reviews and google search in my area. i want to expand into surrounding areas. what is the best way to do this ?
You need to make and rank landing pages for the cities around you and possibly try to trigger Google My Business listings via friends or opening office spaces in said cities to start to expand your footprint beyond your current location.
Also, try geo fencing ads in your area. So create a zip code list and bring people in the area to your site. Geo fencing gives you an edge over larger industries blanketing the cpc across the entire country.
