Google uses many factors in ranking. Of these, the PageRank algorithm might be the best known. PageRank evaluates two things: how many links there are to a web page from other pages, and the quality of the linking sites. With PageRank, five or six high-quality links from websites such as www.bbc.co.uk and www.timesonline.co.uk would be valued much more highly than twice as many links from less reputable or established sites.

Summary: How Does PageRank Work?

1. PageRank is only one of numerous methods Google uses to determine a page’s relevance or importance.
2. Google interprets a link from page A to page B as a vote, by page A, for page B. Google looks not only at the sheer volume of votes; among 100 other aspects it also analyzes the page that casts the vote. However, these aspects don’t count, when PageRank is calculated.
3. PageRank is based on incoming links, but not just on the number of them – relevance and quality are important (in terms of the PageRank of sites, which link to a given site).
4. PR(A) = (1-d) + d(PR(t1)/C(t1) + … + PR(tn)/C(tn)). That’s the equation that calculates a page’s PageRank.
5. Not all links weight the same when it comes to PR.
6. If you had a web page with a PR8 and had 1 link on it, the site linked to would get a fair amount of PR value. But, if you had 100 links on that page, each individual link would only get a fraction of the value.
7. Bad incoming links don’t have impact on Page Rank.
8. Ranking popularity considers site age, backlink relevancy and backlink duration. PageRank doesn’t.
9. Content is not taken into account when PageRank is calculated.
10. PageRank does not rank web sites as a whole, but is determined for each page individually.
11. Each inbound link is important to the overall total. Except banned sites, which don’t count.
12. PageRank values don’t range from 0 to 10. PageRank is a floating-point number.
13. Each Page Rank level is progressively harder to reach. PageRank is believed to be calculated on a logarithmic scale.
14. Google calculates pages PRs permanently, but we see the update once every few months (Google Toolbar).

Search engine optimization (SEO) is the process of improving the volume or quality of traffic to a web site from search engines via "natural" or un-paid ("organic" or "algorithmic") search results as opposed to search engine marketing (SEM) which deals with paid inclusion

Typically, the higher a site appears in the search results list, the more visitors it will receive from the search engine. SEO may target different kinds of search, including image search, local search, and industry-specific vertical search engines. This gives a web site web presence.

As an Internet marketing strategy, SEO considers how search engines work and what people search for. Optimizing a website primarily involves editing its content and HTML and associated coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines.

Search engine optimisation maybe offered as a stand-alone service or as a part of a broader marketing campaign.

Because effective SEO may require changes to the HTML source code of a site, SEO tactics may be incorporated into web site development and design.

The term "search engine friendly" may be used to describe web site designs, menus, content management systems, images, videos, shopping carts, and other elements that have been optimized for the purpose of search engine exposure.
