Understanding search engines and how they work will help you to better understand how to use them. If you can grasp the ideas and the concepts of search engines then you are on the right path to being able to put them to use for you. Search engines can be rather confusing, but through a direct and simple explanation you should be able to get the basic understanding you need to know how search engines work and think.

As you no doubt already know, search engines are used to index websites and web pages. In other words, search engines regularly scan the Internet for content and then index websites and web pages accordingly. This is why a person can enter certain criteria into the search box, and once they hit the enter key, they are supplied with hundreds of thousands of results.

The first step in how a search engine operates and gathers information is crawling the web. To do this the search engine uses software called a crawler or spider. The crawler or spider will follow links throughout the web to scan content. They are usually only able to scan text based content, so java script, videos and anything password protected will not be recognized and therefore will not be used by the crawler or spider.

Once the crawler or spider has done its work, the gathered information is then indexed. The index is like a large database and is serves as the main information bank for the search engine to use when internet users do a search. Within the index, keywords or keyword phrases are used to assign each web page and website to specific search terms that internet users may use. This is where the websites and web pages are ranked and organized into the order they will appear in the search results.

Of course the next step happens when a person types in search terms, as you’ve more than likely done many times already in order to find specific information. If you have, then of course you know that once you type in your search and you press the enter key, you end up getting pages and pages of results. This is because the search engine has taken your search terms and compared it to the information stored in the database so that your request can be processed. Interestingly enough, all the different search engines make use of their own process in order to determine which websites and web pages should appear in the search results. As soon as the search engine has finished processing your request, the results are displayed on your screen where you can then choose which web site or web page you wish to view.

Of course all search engines are different due to the fact that they all use different algorithms, and this is why you would be presented with different results from the different search engines even if you typed in the exact same search criteria. This is largely because the different algorithms place emphasis on different factors such as links, meta tags, and keyword density. The results you get will depend largely on which factors are considered to be more important by each of the search engines. Another thing to bear in mind is that the search engines change their algorithms frequently which of course make things even more complicated than they already are.

Of course when you decide to optimize a web page for the search engines, it can be extremely advantageous if you know which algorithms the search engines use. This is why SEO (search engine optimization) has basically become a science nowadays, simply because it’s vital for successful Internet marketing. Basically, SEO involves adding fresh content to your website or web page regularly, and it means that you’ll continuously have to be making certain changes in order to maintain a high ranking for your specific keyword and keyword phrase.

Having an understanding of how search engines operate, and the methods they use for ranking websites is a huge advantage with regards to search engine optimization. However, because these factors are continuously changing, your SEO efforts will need to be ongoing if you want your site to remain at the top of the page.
