What is a Web Crawler?
A web crawler (also called a spider or bot) is a software program that browses websites automatically and reads their pages.
Think of a librarian going through a gigantic library where new books are continuously being added every second. The librarian reads each book, writes down what it's about, and takes notes so others can find the proper one quickly later. That's basically what a crawler does but on websites, not books.
Search engines like Google and Bing use these crawlers to discover, read, and classify the information available on the internet.

How Do Web Crawlers Work?
Let's take it step by step. Crawlers work in a simple loop:
They begin with a set of sites to go to. These may be big popular sites or pages submitted by people.
They go to one page, scan all the text, images, and code.
They look for links on that page (such as a menu or article links).
They click on those links and do the same thing on the new pages.
They just keep doing it repeatedly like a speedy, constant explorer.

Real-life Example:
Suppose a crawler comes to your blog home page. It finds links to your other blog pages such as:
/how-to-start-a-blog
/best-free-WordPress-themes
It will click on those links (just like a human would), crawl those pages, and then move to any links there.

Suppose you've just released a fresh blog post or created a new website. You'd like folks to be able to see it, correct? Well, if a crawler doesn't discover and read your page, search engines won't even be aware it's there. Which means:
1) Your site will not appear in Google search
2) No one will notice your content unless they happen to know your URL.
3) Crawlers are like internet scouts. If they don't exist, your content remains a secret.

The internet is constantly changing, new pages emerge, old ones disappear, and others are modified. Crawlers visit sites regularly in order to observe what's new or has been changed. That way, search engines can:
1) Show fresh, accurate results
2) Delete old or broken pages
3) Understand what's currently relevant
Without crawlers, search engines would be presenting you with information from several months or even years ago.

Before humans view your content in search, crawlers do. Imagine it this way:
Humans visit your site after crawlers visit your site. So, you'll want to ensure your website is friendly, not only to visitors, but to crawlers too.
