The approach that needs to be taken to SEO by businesses that operate on in multiple sites and locations is somewhat different to that for single-site businesses.
The basic principles are basically the same but given that you would want each individual site to rank highly for searches related to that location, there are some local SEO techniques you can implement to help with that cause.
These tactics come under the heading of ‘Multiple Location SEO’ and this can apply in a number of scenarios such as the three below.
1) Your business has more than one physical location/store/site and you wish to optimise for each of them.
2) Your business is online, rather than a brick and mortar business, and you wish to target multiple locations.
3) You operate a franchise business and wish to do SEO for individual franchisees in different towns and cities.
Multiple location SEO can be implemented when there are just two locations, two hundred locations, or two thousand locations that you wish to optimise for. One of the keys to this is to make sure that the search engines and especially Google have accurate and up to date information relating to each location.
