Let's say that we're talking about keywords where everybody has high authority and have a good bunch of good quality BL. I was wondering, in that situation, how important can the domain age be.
For example, keyword "broadband" in google.co.uk (
http://www.google.co.uk/search?hl=en...e+Search&meta=) the first result has less BL than the next ones, but is registered in 1996, so I's wondering if that can be an important factor. Obviously, in order to rank in the Top10 for such a keyword with 83 million results, all sites have good optimisation.
