A Web crawler is an Internet bot which systematically browses the World Wide Web, typically for the purpose of Web indexing (web spidering). Web search engines and some other sites use Web crawling or spidering software to update their web content or indices of others sites' web content.

Spiders belong to a group of animals called “arachnids”. Scorpions, mites, and ticks are also part of the arachnid family. Arachnids are creatures with two body segments, eight legs, no wings or antennae and are not able to chew.

Spiders, Robots and Crawlers are all the same.

The search engine spiders, crawl throughout the web. The content they come across are indexed in their massive search indices. The webpages that are indexed, are grouped according to their authority, trust, high-quality content and the number of backlinks.

The job of these search spiders is to crawl the entire web 24 x 7.

Another term to take account of is, crawl rate. Crawl rate refers to the rate at which the search spiders crawl a particular site or blog.
Any authoritative sites like NY Times, Forbes have highly crawl rates. Because they are authoritative and the content updation is too frequent.

However, the question may arises. How do search spiders crawl the Internet?
First they make a list of highly authoritative sites like NY Times, Forbes, TechCrunch, BBC News, etc. they crawl these sites first. And then they move on for crawling the backlinks, in those authoritative sites. Like this then make use of the backlinks from all the sites (starting from authoritative sites) to crawl the entire web.

While crawling they analyze the quality and authority of the blog content. And take that into account while placing the results in SERPS.
