Backlink from subdomain of .edu site

Is there any difference between the value of backlink from

• xyz.edu
• blog.xyz.edu
• xyz.edu/blog

I am asking this because commenting on blog.xyz.edu is much easier than that on xyz.edu.

 

xyz.edu is much stronger because it`s not subdomain. but still i would grab aby edu link i can find

 

* xyz.edu - would be the best
* xyz.edu/blog - then this
* blog.xyz.edu - last would be this one

 

I would say that they have the same value unless it contains .edu

 

When calculating the value of backlink don't you put pagerank into consideration or it is different with dot edu domain names?

 

I think this is right.....

 

totally agree .best answer

 

that's not true.the value is decreased on subdomains

 

blog.xyz.edu is much easier than that on xyz.edu

also has less value than xyz.edu

 

Thanks for the help.

 

Ya.But getting a backlink from xyz.edu is almost impossible unless you are prepared to throw some money.
