There's life beyond Google.
I was having a conversation recently about the way Kelkoo, Dealtime and suchlike have successfully spamdexed Google for any product reviews. I've just found that Teoma
seems much more resistant to this.
As an example, compare the results of a query for reviews of a specific SATA-II HBA:GoogleTeoma
The google query can be improved by excluding "price" and "prices", but that risks filtering out useful reviews.
