What is reptile technology?

Generally speaking, a crawler is a program or script written in code, which helps you to filter and screen the massive information on the Internet, automatically grab the information you want from the website in batches, and sort it. Web crawler is also called web spider. If the Internet is compared to a spider's web, then this program or script is a spider crawling around on the Internet. In a word, the automatic retrieval of Internet information is actually a means to obtain data. At present, common search engines are inseparable from reptiles. For example, the crawler of Baidu search engine is called Baidu spider. Baidu Spider automatically crawls through the vast amount of Internet information every day, filtering out better information for inclusion. When you search for related keywords, you will immediately present the corresponding information in front of your eyes according to certain sorting rules.
