How does the search engine work?

Any content that appears in the search results is first and foremost visible to the search engine. It is important that your content is visible to search engines. If your site is not visible to search engines then there is no other way to show your content on SERPs (Search Engine Results Page). In this post we will tell you what a search engine is and how search engine works. First of all, what is a search engine?

What is a search engine?

We use search engines to do some searches on the internet. It consists mainly of two things – a database of information and algorithms that decide which results to return and rank for a query. Like Google.

The Google search engine is the most widely used search engine on the Internet. Internet content is inaccessible to us without a search engine.

How does search engine works?

The search engine has to perform some functionality to make any site visible in the Search Engine Results Page. Any search engine has three main functions: crawling (discovering content), indexing (tracking and storing content), and ranking (placing results in the most relevant order.)

When you do a search, the search engine returns the matching pages and the algorithm ranks them according to relevance.

Scheduling: Scheduler emphasizes the importance of new and well-known URLs. And then he decides when to crawl the URL again and again.
Crawling: Crawler is a computer program that downloads web pages. Search engine regularly discovers new pages by re-crawling known pages.
Parsing: Parser extracts the link from the page along with other key information. It then sends extracted URLs to the scheduler and indexes the extracted data.
Indexing: Indexing is where the information from the crawled pages is added to a database called search index.
The mechanisms used by search engines to build web indexes include scheduling, crawling, parsing, and indexing.

How does Search Engine crawl the web?

Crawling is a search engine discovery process that involves sending a set of search engines called crawlers or spiders to search for new and updated content.

Content can be image, video, webpages, pdf anything. Discover the contents with the help of crawler links.

Googlebot selects some known webpages to start the discovery process and then finds the new URL by following the links available on those webpages. Following the new links available on the page, Googlebot finds new content and adds it to its index.

Index is Google’s database where Google searches for new contents and stores them.

What is indexing?

The search engine performs the indexing tab when the crawled data is processed and inserted into the database. Simply put, indexing is the process of adding web pages to Google search. Google uses a meta tag to crawl your page (index or non-index). Google crawls and indexes your site by looking at it.

If you use a no-index tag, Google will not crawl or index your site. So if you want to index and rank your site in Google, you should use index tag on your site.

What is the search engine ranking?

This is the final stage of search engine work in which the search engine displays the most useful and relevant content in a particular order. Google uses algorithms to improve search results so that only genuine information reaches the user.

Google or any other search engine judges relevant information based on a wide range of ranking factors. Google’s current rank brain algorithm is an Artificial Intelligence based machine learning system that helps its users display the most relevant information.

When a search engine logs in to do a search, the search engine displays the most relevant content in its index based on the score of the present content. The search engine displays the results in the SERP in an order based on relevance, which is called ranking.
Simply put, the higher the rank for a Google or any other search engine, the more relevant it is to Google or any other search engine.

If you want search engines to crawl certain pages of your website then you can instruct search engines to use no follow tag so that they do not crawl your pages.

But if you want your content to be accessible to searchers, you need to make your content accessible to crawlers.

There are some important Google ranking factors that you need to follow in order to rank high in Google. You can rank your website in high position by following these factors.

For a high-ranking page on Google, you need to keep in mind the SEO factors of your website.
