I have read the Google is about to lower the weight of having an exact match keyword domain name. I found this quote from Matt Cutts of Google:
"we have looked at the rankings and the weights that we give to keyword domains, and some people have complained that we are giving a little too much weight for keywords in domains. So we have been thinking about at adjusting that mix a bit and sort of turning the knob down within the algorithm, so that given 2 different domains it wouldn't necessarily help you as much to have a domain name with a bunch of keywords in it. - Matt Cutts"
So does this mean all of those sites like "productnamereview.com" will start ranking worse? Confused about this, does anyone know because im thinking of doing some of these exact domain match sites.
