Search engines try to match words used in queries with words found on pages or in links pointing to those pages when providing search results.

Often, the order that pages are returned to a searcher are based upon an indexing of text on those pages, text in links pointing to those pages, and some measure of importance based upon link popularity.

Before pages are served to a viewer, however, they may be reranked for one reason or another. Here are some possibilities:

1. Filtering of duplicate, or near duplicate, content

Search engines don’t want the same page or content to fill search results, and pages that are substantially similar may be filtered out of search results.

2. Removing multiple relevant pages from the same site

It isn’t uncommon for more than one page from a site to be relevant to a search query. Search engines try to limit the amount of pages displayed in search results from the same site. If there is more than one page from a site that ranks for a search, a search engine may show a second result from that site after the first result, indenting the second page, and inserting a link to “more results from this site.” Additional results may not be shown.

3. Based upon personal interests

A search engine may try to rerank results for a search to a specific searcher based upon past searches and other tracked activity on the web from that person. This kind of reranking may rely upon a person logging on to a personalized search.
