It is only by understanding search engines that you’ll ever been in a position to use them effectively. Providing you can understand the basic concept of how a search engine works, then you can be rest assured that you will soon be able to use them to your own advantage. Even so, you need to realize that search engines can be confusing at the best of times, and this is why you need a simple, straightforward explanation, rather than a mountain of technical jargon.

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 process of a search engine is for it to crawl the Internet, and in order for it to do this, it uses highly advanced software known as a crawler, spider, or bot. Essentially, these crawlers will crawl the web and follow links so that they can then scan available content, although it should be kept in mind that they are unable to scan anything which his password protected. Likewise, they cannot scan JavaScript and videos, in that they’re designed to scan text only.

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.

The next thing that happens is the search by an internet user. You have probably used a search engine to find information, so you know that you type a term into the search engine, press enter and you get pages of results. The search engine will take the term you enter, compare it to the database and process the search request. Each search engine has its own way to process and figure which websites and web pages match your search term. These are called algorithms. Once the search engine has processed the request the results are returned to you and you get the pages of relevant websites and web pages.

Because all the search engines use different algorithms, you will get different results from all of them even if your search term is identical. This is mostly due to the fact that different algorithms tend to place more emphasis on different factors, and while some may view keyword density as the most important factor, others for example may consider links or meta tags to be more important. Just to make matters even more confusing, all the major search engines change their algorithms regularly.

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.

Understanding how search engines work and how they rank websites can be a major help in SEO. You will have to continuously keep up on SEO for your website, though. As mentioned, search engines are always changing their criteria for ranking websites, so you need to be changing with them in order to ensure you stay ranked high.
