Although he ranks well for his main target phrases on the other SEs, Google has simply catalogued more pages (he has 200+ pages).
This is clearly unhealthy, and we are trying to increase the traffic from other sites, but it may not be that unusual.

Lotus Google is good for the UK but I find Lycos.co.uk good for traffic also. They generate about 60% of what Google refers to us. Alta Vista UK is poor now and the big surprise package for me is ASK. They at times generate the most UK hits for me, I asssume its something to do with the fact that it was voted number UK SE and appears on TV fairly regularly. Yahoo UK is average and refers a similar amount to Lycos. The only other one of note would have to be BT Looksmart, they provide the search results for lots of UK ISPs ie BT, NTL etc.
