Vanskeligere å dominere Google med subdomener: Googles Matt Cutt melder at Google nylig har gjort algoritmeendringer som gjør det vanskeligere (dog ikke umulig) å vise flere resultater for samme domene ved hjelp av subdomener.

For several years Google has used something called “host crowding,” which means that Google will show up to two results from each hostname/subdomain of a domain name. That approach works very well to show 1-2 results from a subdomain, but we did hear complaints that for some types of searches (e.g. esoteric or long-tail searches), Google could return a search page with lots of results all from one domain. In the last few weeks we changed our algorithms to make that less likely to happen in the future.
