I have created two similar websites relating to monetary systems. So far, one appears to be loved by Google and the other hated. I'm struggling to work out why.

The successful one is fullreservebanking.com. If you type in "full reserve banking" into Google, my site appears 2nd in the list behind Wikipedia.

The unsuccessful one is fractionalreserves.com. If you type in "fractional reserve banking" into Google, it's nowhere to be seen.

This is a mystery to me because both sites were created by me with the same design philosophy, both in pure html. Both are packed to the rafters with references to, and information about, their respective subjects.

One issue I'm worried may be the cause is to do with the location of the sites. I got a web hosting package from hostmonster.com for fullreservebanking, but fractionalreserves is just an "add-on" which sits on a subdirectory of fullreservebanking. I wonder if Google somehow detects this and treats it as a less significant website?
