The Power of  Google Crawler

How to Harness

Google's crawlers are grouped into three categories: Googlebot, special-case crawlers, and user-triggered fetchers. IP addresses for each type are available in a JSON file - https://developers.google.com/search/docs/crawling-indexing/verifying-googlebot.

1. GoogleBot

Googlebot is the primary crawler for Google's search products and always follows the robots.txt rules.

2. Special-Case Crawlers

Special-case crawlers are designed to perform specific functions, such as AdsBot, and may or may not follow robots.txt rules. 

3. User-Triggered Fetchers

Special-case crawlers are designed to perform specific functions, such as AdsBot, and may or may not follow robots.txt rules.
