A search engine operates, within the following order: 

How Search Engines Work

Web search engines work by storing information a few sizable amount of sites, which they retrieve from the WWW itself. These pages are retrieved by an internet crawler  - an automatic browser which follows every link it sees, exclusions are often made by the utilization of robots.txt. The contents of every page are then analyzed to work out how it should be indexed. Data about sites is stored in an index database to be used in later queries. 

Some search engines, like Google, store all or a part of the source page referred to as a cache also as information about the online pages, whereas some store every word of each page it finds, like AltaVista. 

This cached page always holds the particular search text since it's the one that was actually indexed, so it are often very useful when the content of the present page has been updated and therefore the search terms are not any longer in it. This problem could be considered to be a light sort of linkrot, and Google's handling of it increases usability by satisfying user expectations that the search terms are going to be on the returned website.

 This satisfies the principle of least astonishment since the user normally expects the search terms to get on the returned pages. Increased search relevance makes these cached pages very useful, even beyond the very fact that they'll contain data which will not be available elsewhere.

When a user involves the program and makes a question , typically by giving keywords, the engine looks up the index and provides an inventory of best-matching sites consistent with its criteria, usually with a brief summary containing the document's title and sometimes parts of the text. Most search engines support the utilization of the boolean terms AND, OR and to not further specify the search query. a complicated feature is proximity search, which allows you to define the space between keywords.

The usefulness of an enquiry engine depends on the relevance of the results it gives back. While there could also be many sites that include a specific word or phrase, some pages could also be more relevant, popular, or authoritative than others. Most search engines employ methods to rank the results to supply the "best" results first. 

How an enquiry engine decides which pages are the simplest matches, and what order the results should be shown in, varies widely from one engine to a different. 

some employ the controversial practice of allowing advertisers to pay money to possess their listings ranked higher in search results.

The overwhelming majority of search engines are travel by private companies using proprietary algorithms and closed databases, the foremost popular currently being Google, MSN Search, and Yahoo! Search. However, Open source program technology does exist,

How to Get the Best Deal on Your SEO Project

If you own or manage a business Website, chances are you are at least somewhat familiar with the concept of search engine optimization (SEO). You may have read any number of books and articles on the subject and possibly given it a try yourself. Or perhaps, after exhaustive research, you decided that your time is better spent in your area of expertise. If that's the case, I have some good news for you. There is such a thing as affordable search engine optimization.

 In fact, when you know what to look for, it can be a real bargain.

Step One - 3 Simple Questions:

The first step is estimating some target market information. Just ask a few simple questions and write down the answers that you come up with. You'll need this information later:

1. How many people do you think are looking for what you offer?

2. What keywords are they using in search engine searches?

3. Which keywords are the most popular to meet your needs?

Step Two - Verify:

Now that you have your initial estimates, let's validate the information. Visit Overture.com's Advertiser Center and try their Search Term Suggestion Tool 

Type in any term that you think is close to what your potential visitors are looking for. You will see how many searches were performed, on the Overture search system, for the previous month. TIP - Use a general search term to start with.

Now you have the single most important advantage when dealing with any trained business professional - you are informed!

Step Three - Make it Happen:

Now that you have this great information, you want to see it implemented. recommend a visit to SEO Partner. SEO Partner (www.SEOPartner.com) really lives up to its slogan "search engine optimization on your terms".

They have assembled an enormous talent pool of SEO developers, who actually compete to work on your project. It does not cost you anything to post your optimization projects. To operate the service, they accept a small commission from the SEO developers which is only a fraction of what developers would normally spend on marketing efforts alone.

Finally, there's one of my favorite features. SEO Partner protects you from those less scrupulous SEO 'experts' you read about more and more with their protective escrow payment system.

Step Four - Track Your Progress:

Finally, once you have your campaign underway, you really need to track your progress. There are some great tools available for that purpose. Here are links to some of the better products that I have worked with:

A good tool is worth the investment but there are so many great options out there that it's best to shop around and try before you buy.
