2-3 levels deep or 2-3 clicks from main page?

[net_rambler]

Hello!

I read many times that it is good to have site structure no deeper than 2-3 levels, like this

index.htm
level_one/index.htm
level_one/level_two/index.htm

if one wants that those pages will be in SERPs quite easy found.

I use mod_rewrite and all my pages looking like they are directly under root...

index.htm
page1.htm
.....
page_100_000.htm

But they are sometime 3-4 clicks away from root of the site...

Is "three click" equal to "three level" model?
Or it is not the same...

If it is not the same is there reasonable ammount of pages that I should not exceed to be placed under root of site?

Is it Ok to have 10 000 pages directly under root of site? They are not pointed from root page - index.htm - they are 1-2-3 clicks away....

I dont think directory structure is important, just the clicks from home page, thats how the spider sees your site and how PR is calculated. There may be some advantage in deeper directory structure in terms of including more keywords in url, but thats another matter.
