Search engine optimization is a set of methods aimed at improving the ranking of a website in search engine listings. The term also refers to an industry of consultants that carry out optimization projects on behalf of clients' sites. SEO, or "white hat SEO", is distinguished from "black hat SEO", or spamdexing by methods and objectives. Spamdexing uses a variety of deceptive techniques in an attempt to manipulate search engine rankings, whereas legitimate SEO focuses on building better sites, and using honest methods of promotion. What constitutes an honest, or ethical, method is an issue that has been the subject of numerous debates.

Search engines display different kinds of listings in the search engine results pages (SERPs), including: pay-per-click advertisements, paid inclusion listings, and organic search results. SEO is primarily concerned with advancing the goals of a web sites by improving the number and position of its organic search results for a wide variety of relevant keywords. SEO strategies can increase the number of visitors, and the quality of visitors, where quality means visitors who complete the action the site intends (e.g. purchase, sign up, learn something).
 
Google was started by two PhD students at Stanford University, Sergey Brin and Larry Page, and brought a new concept to evaluating web pages. This concept, called PageRank, has been from the start important to the Google algorithm [1]. PageRank relies heavily on incoming links and uses the logic that each link to a page is a vote for that page's value. The more incoming links a page had the more "worthy" it is. The value of each incoming link itself varies directly based on the PageRank of the page it comes from and inversely on the number of outgoing links on that page.

With help from PageRank, Google proved to be very good at serving relevant results. Google became the most popular and successful search engine. Because PageRank measured an off-site factor, Google felt it would be more difficult to manipulate than on-page factors.

But manipulated it was. Webmasters had already developed link manipulation tools and schemes to influence the Inktomi search engine. These methods proved to be equally applicable to Google's algorithm. Many sites focused on exchanging, buying, and selling links on a massive scale. PageRank's reliance on the link as a vote of confidence in a page's value was undermined as many webmasters sought to garner links purely to influence Google into sending them more traffic, irrespective of whether the link was useful to human site visitors.

It was time for Google—and other search engines—to look at a wider range of off-site factors. There were other reasons to develop more intelligent algorithms. The Internet was reaching a vast population of non-technical users who were often unable to use advanced querying techniques to reach the information they were seeking and the sheer volume and complexity of the indexed data was vastly different from that of the early days. Search engines had to develop predictive, semantic, linguistic and heuristic algorithms.

A proxy for the PageRank metric is still displayed in the Google Toolbar, but PageRank is only one of more than 100 factors that Google considers in ranking pages.

Today, most search engines keep their methods and ranking algorithms secret. A search engine may use hundreds of factors in ranking the listings on its SERPs; the factors themselves and the weight each carries may change continually.

Much current SEO thinking on what works and what doesn't is largely speculation and informed guesses. Some SEOs have carried out controlled experiments to gauge the effects of different approaches to search optimization.

The following, though, are some of the considerations search engines could be building into their algorithms, and the list of Google patents [2] may give some indication as to what is in the pipeline:

»» Age of site
»» Length of time domain has been registered
»» Age of content
»» Regularity with which new content is added
»» Age of link and reputation of linking site
»» Standard on-site factors
»» Negative scoring for on-site factors (for example, a dampening for sites with extensive keyword meta tags indicative of having being SEO-ed)
»» Uniqueness of content
»» Related terms used in content (the terms the search engine associates as being related to the main content of the page)
»» Google Pagerank (Only used in Google's algorithm)
»» External links, the anchor text in those external links and in the sites/pages containing those links
»» Citations and research sources (indicating the content is of research quality)
»» Stem-related terms in the search engine's database (finance/financing)
»» Incoming backlinks and anchor text of incoming backlinks
»» Negative scoring for some incoming backlinks (perhaps those coming from low value pages, reciprocated backlinks, etc.)
»» Rate of acquisition of backlinks: too many too fast could indicate "unnatural" link buying activity
»» Text surrounding outward links and incoming backlinks. A link following the words "Sponsored »» Links" could be ignored
»» Use of "rel=nofollow" to suggest that the search engine should ignore the link
»» Depth of document in site
»» Metrics collected from other sources, such as monitoring how frequently users hit the back button when SERPs send them to a particular page
»» Metrics collected from sources like the Google Toolbar, Google AdWords/Adsense programs, etc.
»» Metrics collected in data-sharing arrangements with third parties (like providers of statistical programs used to monitor site traffic)
»» Rate of removal of incoming links to the site
»» Use of sub-domains, use of keywords in sub-domains and volume of content on sub-domains… and negative scoring for such activity
»» Semantic connections of hosted documents
»» Rate of document addition or change
»» IP of hosting service and the number/quality of other sites hosted on that IP
»» Other affiliations of linking site with the linked site (do they share an IP? have a common postal address on the "contact us" page?)
»» Technical matters like use of 301 to redirect moved pages, showing a 404 server header rather than a 200 server header for pages that don't exist, proper use of robots.txt
»» Hosting uptime
»» Whether the site serves different content to different categories of users (cloaking)
»» Broken outgoing links not rectified promptly
»» Unsafe or illegal content
»» Quality of HTML coding, presence of coding errors
»» Actual click through rates observed by the search engines for listings displayed on their SERPs
»» Hand ranking by humans of the most frequently accessed SERPs
