file naming conventions/extractability

[BEFOR]

I've seen secondary tags having terms and numbers seperated by dots, for example:

yourdomain.com/schedule.window_cleaning. 200.html

Is this done in order to extract the term "window_cleaning" and "200" perhaps to Insert as a table values?

I need to determine the best file naming structure to work with forms and table Inserts with php (example above would be only if I rename .php extension to .html)

Ideally I need a format which is recognizable, scalable and containing values that are extractable. There are 40+ forms to create. At the same time I'm wondering why I see no one in my business using templates for such projects (especially for Updates to these pages).

Any suggestions?

My guess is that they are using the URL for search engine stats or easy recognition of the page.

Generally, when you see a URL like google.com/search.php?q=stuff

the q is the extracted variable and the stuff is the content of the variable that they are going to use in the page.

When you see google.com/website.traffic.free.html

They are trying to get search engines to pick up those keywords "free website traffic" and place them higher on the results pages.

...just my 2 cents...
