I have tried something like that, but couldn't upload it in that form. It probably sounds pretty dumb, but I have no idea how to actually get that structure on the server.
Following that structure in the way I envision it, it would be:
followed by 3 pages "at the same level" i.e. all 3 directly coming of the viessmann/boilers page like this:
B-B-R-L/viessmann-boilers/viessmann-boilers-install/, B-B-R-L/viessmann-boilers/viessmann-boilers-service, B-B-R-L/viessmann-boilers/viessmann-boilers-repair
If I put the folder /viessmann-boiler-service/ inside the folder /viessmann-boiler-install/ would the install page not come from the "service" page instead of the "viessmann" page?
Is it possible to avoid calling any other page index, apart from my "real index" page? To keep thins simple for myself ( I am still very green when it comes to site building ) I store the pages on my computer under exactly the same name as they appear on the web.
Like above, unless there is a big problem with repeatinig viessmann, I really prefer doing it that way. The viessmann example is just a first attempt. Once that is in place, I will create many more strucutres like that for different makes and systems. If I don't include the make in the page title, I will lose the plot about which page is what boiler.
As I am still learning, I upgrade, add and change things on a regular basis and will need to be able to match what is on my computer with what is on the server both fast and without mistake.
At this stage, I can't afford to be worried about conforming to "good programming rules". I am a heating engineer that suddenly found himself forced to do his own website building. As long as it works in a stable manner, I am happy.
Once I have learned how to make it work, I will spend time on learning how to program things "the way it should" and do the next website properly. Promise.
My plan is to no deeper than 3 levels unless really "necessary".
This page has info about the company e.g. origin, size, location, reputation, but nothing about install/repair/service.
And so on e.g Condensing boiler etcc. Combi boilers etc Open Flue boilers etc.
I am pretty good at what I do for a living, and for the coming year, I want to use my abillity to write about what I know at length,and present that in a way that is easy to follow for the reader to compensate for my lack of website presentation skills. Even though my site looks very tatty, the feedback is very good.
Many thanks for your elaborate answers.
