Custom Domain Vs Free Sub Domain for SEO

[jombay]

What is your take on custom domain vs free sub domain for SEO? (example.com vs example.blogspot.com)

Say if I have 10 links from 10 different domains but all hosted on blogger.com, will it still have the same link benefit as ones hosted on different hosting account?

I am assuming it might be less due to the same C class IP appearing for blogger hosting.

What do you think?

If they validate their subdomain in GWT then goolge will know they are a different entity, i think with blogspot they will know this anyhow.

It is my belief that same ip of c-class is not a problem unless you have a huge amount of your links from the same.

Sometimes whole towns share the same c-class, very large hosting companies like discountASP host all clients on the same ip. I think common sense will tell search engines not to worry unless the numbers are huge.
