How Do Search Engine Work??!
Search engines are basically computer algorithms which help users find the specific information they’re looking for. With literally trillions of pages of information online, without effective search engines, finding anything on the Internet would be almost impossible. Different search engines work in different specific ways, but they all utilize the same basic principles.
The first thing search engines have to do in order to function is to make a local database of, basically, the Internet. Early search engines just indexed keywords and titles of pages, but contemporary search engines index all of the text on every page, as well as a great deal of other data about that page’s relation to other pages, and in some cases all or a portion of the media available on the page as well. Search engines need to index all of this information so that they can run searches on it efficiently, rather than having to run around the Internet every time a search query is sent.
