Crawler (Web Crawler)

A web crawler is an automated internet bot systematically programmed to browse the World Wide Web, typically for the purpose of web indexing. Search engines like Google operate massive fleets of crawlers (like Googlebot) that read billions of pages to update their search index. If a crawler cannot access, render, or understand your website, your business does not exist in search results. Technical SEO is fundamentally the practice of removing roadblocks for these crawlers, from optimizing server response times to structuring XML sitemaps, every technical adjustment is designed to feed crawlers exactly what they need.

Crawler Simplified

A crawler is a software program used by search engines to read the internet. It automatically jumps from link to link, scanning websites and saving the information so it can be shown when someone searches on Google.
