I know that ideally businesses that operate as franchises should have 1 site with separate location pages. However, I have a slightly different issue. Each location is owned by a different parent company, and named accordingly. For example, there is "Location by XYZ Company" and "Location by ABC Company." In addition, each location, while carrying similar products, does not carry the same exact products and brands. So my question is how would you go about writing the content for each of these sites, keeping the same tone but avoiding duplicate content?
