What are list crawlers?
A list crawler is a bot that is used to crawl through lists of items, typically in an online database or directory, and extract information about each item in the list. List crawlers are used to collect data from online sources so that it can be sorted and organized into a usable format.

How do list crawlers work?
List crawlers are computer programs that scan websites and create lists of the links they find. These lists are then used by search engines to index the web.
List crawlers work by starting at a seed URL, typically a homepage or sitemap, and then following the links on that page to other pages. As they crawl, they keep track of the links they find and add them to their list.
There are a few different ways that list crawlers can find new links to crawl. The most common is by following the links on pages they’ve already crawled. This is sometimes referred to as “breadth-first” crawling.
Another common method is to prioritize crawling pages that are linked to by many other pages. This is sometimes referred to as “depth-first” crawling.
List crawlers typically run on a schedule, crawling the web periodically to find new or updated content. Some crawlers may also be triggered to crawl a site more frequently if its content changes frequently.
