Custom Search

Every day search engines provide an average of 300 million searches. To achieve the best long term result in search engine positioning, you must be sure you know how a search engine works.
There are 3 main components in a search engine which affect the indexing and ranking of your web site.

01.The first one is a software called spider, robot or bot. It goes along the net visiting pages. These spiders take the information and send it to the base: the database or index. Here you can find the list of all the spiders .

02.The index is a sort of catalogue containing a copy of every single page the spider visited. When a spider goes back to your page and finds modifications, the catalogue gets updated. Nevertheless, not all the pages a spider brings back are indexed. Consequently, it is better to look for your URL in the search engines to know if your site has been indexed.

03.The third component is the mechanism of classification. This is the software that matches the keywords a user types in with the database, showing the results. The higher your position, the easier to be found, because 93% of users don't look at more than 3 pages of results.
