If we create a subdomain, such as h ttp://blog.domain.com or h ttp://domain.com/blog which one better? other then position is front or back, which one play good in SEO? Does search engine put either one in higher priority?
as I know subdaomin is only like : blog.domain.com but domain.com/blog is subfolder Thay say blog.domain.com is better for seo
blog.domain.com is subdomain.But domain.com/blog is not the form of subdomain.It's still TLD with a folder behind it.These two are made by different ways.For SEO,I would like to advise you to use the former.
Based on my experience,the subdomain is more better coz G see it as separate domain from your main domain. So it will not leech your PR juice from your main domain.
Yes google treats subdomains as separate domains so I would go for the sub-folder instead. Why spread your PR around thinly? it's better to concentrate it in one place. A blog is not going to 'leech' PR from the main domain, it is going to add to it. Your main domain will also have some age, a subdomain would be brand new and may be sandboxed for a while.
So on a one word domain you can have like buy.car.com new.car.com and this would be better seo for each term?
No, Im saying use subdirectories instead like this: car.com/buy/ car.com/new/ car.com/bmw/ car.com/ford/ One strong site instead of 100 weak ones.
thank guys... i think i better follow the formal one... but does formal sub domain link back to the main domain play a good role at SEO? (since google tread sub domain as separate domain)
IMO you should go with domain.com/blog. I don't think sub domain link back to main domain will really HELP.
