We have a doctor website we did optimize and also got success. Now doctor is opening offices in different cities, should we get a new domain for new office? Most of our keyword are targeted for "City Name + Keyword", so all content pages(5 of them) should we create them for new office and target? Or a sub folder we can target?
I would personally go with using the same site but adding pages for the new location. You can build on the strength of the site. The exception would be if you were targeting different keyword phrases besides city names.
you can add sub pages and optimize them well for those keywords and build some links, that will be fine I don't think you have to go for new domain.
Same site would be better. Add more location and start building backlinks using new keywords. It is always good to have variety of anchored keyword backlinks. At least it won't look spammy and probably google will think it is natural link.
If we get new domain: We can target new keyword and we may be able to get specific keyword working but it may be expensive. what about add a folder for new office and from that we can optimize those pages for new office .. this will save some money. Again any article related to this?
