Datamonitor: Google may target search spam with domain move

Datamonitor is indicating that the reason for Google’s recent expansion to domain registrar status could be for using its access to the list of recently transferred domains in order to clean up search results. Once a domain would change hands, its pagerank would be reset, avoiding pollution of the Google database from domains having gained pagerank in their previous life. This could, among other things, help stop search engine optimisation outfits snake oil merchants from buying up high-ranking domains and turning them into marketable link pools.
