Factoring in the mechanism of result generation by any search engine, the role of a robot or web crawler is critical. A website crawler is fundamentally an automated software tool that visits individual page of a website and derives a certain amount of data from it. That packet of information is subsequently hived away in an enormous database. This technique is termed as indexing. At the time, a user looks for any specific search term or keyword, the search engines fit those keywords in their database and generates the results for that reason. Therefore, it is easy to understand that web crawling services are the first and most cardinal part of any search engine method.

When a user develops a website, he/she adds a specific amount of data to the coding part of a website. This process may include the keywords or meta-tags, the meta-title and a brief description of a website. The integral part is called on-page activity because the same is placed on the page itself. The entire information plays a seminal part in the processing of a website.

All the information said above is fundamentally placed in the search engines and web crawlers. However, neither of them has any type of interaction with the user. Subsequently, it gets at adding the content for the user, which may be in the form of descriptive content or an article. This is added to the body part of the coding, therefore is visible to the user only. This is also significant since informative and pertinent content is invariably well cherished by the appearance for engines. The website crawler services may also choose some content from this constituent.

The procedure of web crawler data extraction is quite straightforward. The spider/crawler of any specific search engine visits a site and selects the title, its meta-keywords and meta-description. This data is subsequently hived away in the database of the engine. The keyword, title and descriptions are so contented they are at ease for the appearance for engines to get a hold of at the time of generating the results. In the most recent process, when a user keys in any search term in the search box of an engine, the exploring engine fits the search term in the entries of its database. As per the matches, it subsequently generates a list of more pertinent results.
