Seeking information is easy and accessible, thanks to the extent of search engines. These sources of information have piled up the required kind of database and helps you in on some critical material. But have you ever wondered about their function and how it works? Well, if you haven’t, then we don’t blame you. The extent and coverage of these platforms have enabled us to ask for solutions and not the functionality. But minds can be curious and we hope to have piled up on that curiosity. Hence, here’s how search engines work.

Search Engine Index

One of the essential tasks of search engines is to provide you with information in the form of webpages. For that purpose, it needs to gain access to these pages and thus, arrives the search engine index. Webpages that have been discovered get stored into the data structure, known as an index. Apart from the URLs, the Index also includes relevant keywords, type of content, date of update, and so on. All such information will be entitled to provide the best service to an individual when he/she requires access to the same.

Search Engine Algorithm


After understanding all about the search engine index, you need to move forward into the algorithm. The algorithm is set up in a manner so that individuals are blessed with answers. Regardless of the content or place, the algorithm aims to meet their criteria of interest by providing what they need. With aspects being stored in the Index, topics will be displayed in the algorithm. The algorithm works on a few basic fundamentals that are easy to know but hard to master. Such as link building, people can take many years to understand it properly, especially when PBNs are involved.

Exclusions from Search Engine Index

Although the search engine index is vast and consists of numerous pages, at times, things don’t go in the right manner. There are individual pages that are not included in the Index, and various reasons are associated with this exclusion. A primary source for this task is an error page or 404 not found. Apart from that, search engine algorithms will not display content that is duplicate and reeks of low quality. Robots.txt. File exclusions are other pages that also gain exclusion.

The Process


Soon after you search for some content, all relevant pages will be put in by the Index, and the algorithm comes into the picture to rank these pages. Based on the ranking, a set of results will be displayed. This ranking will differ for search engines, and this Bling and Google will not give you the same content. Apart from this ranking, search engines also look into a few other factors such as location, previous history, device and language. So by the end, your information will get processed in this manner, and aspects will reach you in a matter of seconds.
