Sub-Page Extensions

Now I need to know what you meant by that statement.

Is it positive or negative effect?

Can be good and bad – normally it is good. Just keep it natural.

Years ago sub domains were some what frowned upon, however, I’ve seen a number of these aquire top (spot 1) SERP’s at many SE’s lately.

I just today read an article and now I can’t find it. I think it was on webproworld or webpronews. It was about sub domains getting indexed by Google as if they were a totally new site. This has been causing alot of spam and people creating subdomains with Google Adwords for some nice profits. The end result was that Google is currently manually removing all these sub domains.

On another note, if you want to create folders, the main page in that folder will get better rankings if you name it index, default, etc rather than a page name. The search engines prefer this.

Yep. Subdirectories do have an effect on the SERPS

Subdirectories DO NOT reduce PR by anything,

You could have domain.com/foo/foo/foo/foo/foo/foo/foo/foo/
and if it has identical links to domain/foo/ – it will have the same PR.

URL structure has nothing to do with it – (internal) linking determines the PR.

Yep. Subdirectories do have an effect on the SERPS – but nothing to do with PR.

Do search engines prefer certain extensions? For example:

Is any one way better than the other?

1. Name them .html
2. Name them .htm
3. Put the page in a folder with an index page (.htm or .html)

Does it really make any difference?

Typically back in the old days (I’m talking mid 90’s) *.html was normally reserved for Unix and *.htm was for Win Boxes. These days I don’t think it makes any difference, though I’m not a Win box guy.

I think the main issue with sub domains are duplicate content. In other words, if you have casino.yourcasinoportal.com with the same content as your main pages there would be a problem. Otherwise, I have seen many subdomains in google results.

Granted the sub-domain content theoretically resides in a directory, but, it points to whatever.yourdomain.com I’d think then that it would be more favourable to use a sub-domain as apposed to a directory.
