1. Check the robots exclusion protocol
Before crawling or crawling any Web site, make sure that your goal allows data to be collected from its pages. Check the Robot exclusion Protocol (robots.txt) file and follow the rules of the website. Following the rules outlined in the robot exclusion protocol, crawl during off-peak hours, restrict requests from an IP address, and set delays between them.
2. Use a proxy server
Without an agent, web crawling is almost impossible. Choose a reliable agent service provider and choose between data center and residential IP agents according to your task requirements. Using a mediation between your device and the target Web site after using a proxy can reduce IP address blocks, ensure anonymity, and allow you to access sites that may not be available in your area. Note: for more efficient crawlers, choose an agent provider with a large number of IP and locations. For example, ipidea provides overseas 220 + region ip, and ip is exclusive.
3. Rotate the IP address
When you use a proxy pool, it is best to rotate your ip address. If you send too many requests from the same IP address, the target site will quickly identify you as a threat and block your IP address. Proxy rotation makes you look like many different Internet users and reduces your chances of being blocked. For example, the ipidea residential agent supports rotation, and you can customize the rules.
