Google Secrets (5) - How Google Ranks Websites
Google uses a sophisticated and proprietary algorithm for ranking Web sites that
uses over 100 different criteria in the calculation, each of which is given a specific
weighting which can change over time. Because the algorithm can change, specific
techniques that used to work well may no longer work as well over time. This is
important to remember when your site’s ranking seems to change for no apparent
reason. For this reason, optimizing your site should not be considered as a one-time
task. You should always try, test, and refine your efforts.
With that said, the Google algorithm can be broken down into two major groups of
factors:
Keyword (textual) factors. Keyword factors involve how, where and when keywords
are used. Meaning how well your website is optimized for your chosen keywords,
and if those same keywords appear in links that point to pages on your site. Keyword
factors determine page relevance.
Link (PageRank) factors. These include the quantity and quality of links that point
to your site. Link factors determine page importance and are strongly related to
Google PageRank (PR).
Very simply put, Google finds pages in its index that are both relevant and important
to a search for a particular term or phrase, and then lists them in descending order
on a search results page.
