What is a search engine?
Search engines are machines or devices that answer, search, understand, and select a wide variety of content from across the Internet. The main function of a search engine is that when an internet user searches for something, the search engine shows the result according to that search.
Following all the rules of a search engine, your content should be on the first page of the search engine results page. There is no SEO option to ensure this. If your content or website is not found by search engines, it is less likely to appear on SERP. Currently, search engine results pages are called SERPs.
How does a search engine work?
Search engines have three main functions. Which is:
1) Crawling: Searching for all types of Internet content and codes, including URLs.
2) Indexing: At the end of the crawling process or crawling process, these are stored and organized according to certain rules. Once indexed, the information will be displayed in search results by using search and relevance.
3) Ranking: The best content of the indexed content is displayed as relevant and accurate results according to the user’s search periodically.
Does the search engine crawl?
Crawling is a search engine process by which one or more bots/robots find all kinds of new and updated content and code URLs on the Internet (many call it a spider or crawler).
The content can be of different types. Such as website, picture/photo/image, video/audio, pdf, etc .. but keep in mind that these written materials can be found through links on the internet.
The Google bot starts crawling by fetching specific web pages, then links to those web pages and crawls other pages. This way it finds new content through the link and attaches it to the index, which is called caffeine.
Where crawling information is stored in a huge database and when a user searches, the information matches their search.
What is search engine indexing?
After the crawling process, the search engine stores and organizes the information in a huge database according to certain rules. The next time a user searches, it shows relevance to search engines and search results.
Search engine rankings
When a search engine has something to search for the user, the search engine shows the most information that is listed in a huge database/database according to the searcher’s search match. Showing search results in this way is called ranking.
The ranking works according to the algorithms of the search engines. Search engines believe that the website you visit for the first time after a search can provide a specific solution to a user’s problem.
