Sub domain or subfolder which is more SEO friendly?

I am little bit confuse on sub domain and sub folder, which is the best choice.
1. My website all ready have page rank 2 .Now I want create some more section in details. Should I go for sub domain or sub folder? Which one is better?
2. My another question is did my present page rank will follow in all my sub domain or I have to promote individually all sub domains and what is case in case of sub folder ?
3. What you thing which is easy to remember sub domain or sub folder from the point of view of visitor?
Thanks in advance.

Hi mitradebanjan9

Personally, I think you're better off creating a sub folder for the various sections of your website. This would make it easier for your visitors to follow and I don't think it would have any adverse effect on your pagerank.

Hi mitradebanjan9

It's more SEO friendly to use subfolders. That way, any link juice from a higher level can be passed down using internal links. A subdomain is treated as exactly the same as a new, unknown and unrated website; it has to create its own link juice from scratch.

Use of subdomains is more of a marketing choice - e.g. images.google.com, maps.google.com - but for the average website, stick to www (or nothing). As it says in "The Art of SEO", "It is much less expensive to use a subfolder and have slightly less marketing panache than it is to educate through branding and advertising".

One case where subdomains are definately the choice of the day is when developing client sites on your own domain; clientname.kpdirection.com looks quite professional to the client, and its complete lack of link juice means that you can keep that out of the search engines for quite a while (although you really should password protect them as well - but that's another subject).

HTH,

Pete.
