Trying to build a general information portal website, have done kw research but can't decide on weather to have subcategories on the site or only categories. Bc 1 of the categories is very broad, let's say Cars, and then a subcategory of that would be a local service regarding cars. But this service can be in many different cities in that country so many geos. How to go about this? So the category will target 'Cars' as kw and the subcategory 'service x cars' but then what about each page in that subcategory? If each page targets only 1 'geo + service x cars' I'm afraid the page will end up w/ not much text which makes it harder to rank.


But on the other hand, if I have several geos on 1 page that makes it tougher to optimize the page for each geo like kw in Title, H1 etc.
So how to deal w/ targeting so many geo kw's in this same niche under that category or subcategory?


And how can you write enough text for something like this?
