I have a website, where we have a similar structure across all our pages, what differs is the location and product type.
Eg:
When you buy marketing xxx database from us, we tend to provide you with the latest / fresh set of xxx list, so that you are not stuck with the old database which are time sensitive and would not benefit you in any manner. Although we do provide old xxx database at a much reduced price. It is just the old database might be less effective, however, we have customers requesting old database as their marketing strategy allows having one.
Where xxx is the only thing that set it apart. Otherwise rest will be same structure in almost 800 pages.
Post Some cool and relevant answers so far : Now, I want how to avoid being noticed as a spam?, where we are not trying to create doorway pages, we are creating product pages for different locations and the number is around 800.
