How Search Engines Rerank Results

Did you know that the [order of] results you see for
web pages in response to a search query may not
be the same as what other people see?

SEO, a search engine optimization blog, has
published a fascinating post by William Slawski
on why and how search engines rerank search
results. The post is highly readable and may
surprise you. For example, search results may be
ranked by your previous search behaviour or
by community endorsement.

Thanks to Betsy McKenzie at Buffalo for the
