What Are Web Crawlers and How Do They Work?

Web crawlers, also known as web spiders or web bots, are automated programs that systematically browse the internet to collect information from websites. They are primarily utilized by search engines to index content and update their databases. When a crawler visits a website, it examines the page's structure, content, and links to other pages, gathering data that can be used to improve search engine results.

There are several different types of crawlers, each designed for specific tasks. Here are some of the most common types:

Why Are Crawlers Important for SEO?

Crawlers are crucial for search engine optimization (SEO) as they determine how well a website can be indexed and ranked in search results.
