Definition of utopia: a keyword rich, aged domain, with backlinks

[addlet]

I went to a seminar the other day where Brett McFall was saying that an expired domain which did have back links to it can have SEO benefits regardless of the particular niche or name of the domain…(in other words the name of the domain does not matter)

We all know that keyword rich domains certainly have SEO benefits and so do ‘aged’ domains.

In an ideal world you would have a keyword rich, aged domain, with backlinks.

However in a non ideal world which won would win out:

An aged domain.

Or….

An expired domain that had backlinks which you reregistered.

Or…..

A domain that contains the exact keywords you are trying to rank for.

If anyone knows the answer to this non utopian question I would be grateful

Thanks
