How Search Engines Work
Learning how search engines work is the fundamental step in Search Engine Optimization which is the blood of your website's traffic from search engines.
More than 80% of the highly targeted traffic is coming from the search engines.
To make easy money online you have to get highly targeted traffic to your website. This is acheived by your knowledge of how to be ranking high in the search engines. The basic step is to know how search engines work.
Most searh engines have three parts:
Also known as a "spider", "bot", or "robot" is a an intellegent automated software program.
This part of the search engine wanders the web, following links and picking up information for its database. Crawlers do most of their work at times of the day when searh engines are less busy, but they typically visit frequently updated pages more often. This is something to keep in mind when you are working on your pages.
They start crawling the web by visiting first what is called as the authority sites(sites that have very high rank) such as the most valuable web directories as the open directory and Yahoo directory following all the links from them and the process goes on.
Your site's title and text(your content) are the most important thing to a crawler. The fastest way to raise your site's search engine ranking for specific key words is to implement them into your title and your content.
2.The index.
Once the crawler has collected all that text, it is then stored and indexed. This allows people searching for key words and phrases to get results relating to what they were searching for - their search results.
Most sites will incorporate rating systems such as Google Page Rank or Alexa Rankings in positioning your site. These ratings are used in an attempt to ensure that sites that are important receive more traffic than unimportant sites.
To see this in action, go to a search engine and type in a word. You'll see some text on the page saying something like "results 1-10 of 1,234,000".
This means that the search engine's index contains 1,234,000 pages it believes are related to the word you typed. If you wanted to, you could look through all these pages to find the information you're looking for.
In order to understand rating systems more thoroughly consider your own site. When you place links on your site you generally do so to increase your users understanding of the content of your site.
If every site in a particular field links to a particular site, this site is probably very important to that field and should, therefore, be listed highly in the lists of search engine results. This is the basic ideology of Google Page Ranks.
Consider again , a site that receives a great deal of traffic, it probably has some information or service that is very important to its users. Alexa ratings attempt to estimate the amount of traffic that a particular site gets and compare it to the amount of traffic that other sites get.
The closer that a site is to the most trafficed site on the internet, the more likely it is to have important content if it is relevant to search query.
3.The Interface.
Search engines provide a public intrface for users who want to find information on the web. They can type the word or phrase they're searching for, and the interface will run an algorithm to find the pages relevant to their search and display them assuming that they are found in their index.
These algorithms are an important part of the SEO(Search Engine Optimization) business. You'll notice when the algorithms change, the rankings of your website will change with them. No two search engines have the same algorithms. They all work differently, with their unique features, and they will all respond to your website in their own way.
The most popular search engines today include Google, Yahoo, MSN, Alltheweb, and AskJeeves.
