On this element , what will we use? Subdomain or folder?

[imthankyou]

I am in a divided to chose from subdomain or folder.

i think the folder is good for main domain more than subdomain?

Anyone here , can you show me a admonition?

I agree with Anthony, his comments are accepted guidelines. However, it really depends on what the content is you are talking about. If it is a blog, as Anthony assumes, then he is right.

But, sometimes sites want to offer a service or product that does not squarely fall within the product categories currently represented on the site, and they choose to use a subdomain.

You may also want to glance at this:

If I understand your question correctly, you're asking if you should use a subdomain or a path for a particular set of pages or subsite, like a blog. I would recommend using a path (yourdomain.com/blog) over a subdomain (blog.yourdomain.com) because Google treats subdomains almost like entirely different domains, and the subdomain will only benefit slightly from the root domain's authority. Pages that are inside a path however will benefit more greatly from the root domain's inbound links and authority.

Hope this helps.

Thanks,
