So to follow up on the post below. Matt Cutts gave an explanation of the latest algorithm shift towards big brands. It appears it takes into account greater trust exhibited by bigger brand sites.
This was pretty self evident but how are these big brands gaining more trust. Could it just be as simple as:
if $keyword = laptop
then GoogleNumberOne = “dell”
Trust was always a big factor in competitive market. Whats interesting is some of these changes could be human intervention. Could some parts of Google begin to resemble DMOZ, what does this mean for search engine optimisation in general … hmmm
