Static or rotating proxy for product information capture

When grabbing product information, choosing static proxy or rotating proxy (also called dynamic proxy or proxy rotation) depends on your specific needs and the anti-crawler strategy of the target website.

A static proxy means that the same proxy server is used throughout the session or task. This method is simple and easy to use, but once the proxy server is blocked by the target website, the whole session may be affected. Static proxy is more suitable for those who are not strict with the anti-crawling measures of the target website, or you just want to do some simple data grabbing tasks quickly.

Rotating proxy involves using multiple different proxy servers during the session, which can reduce the risk of being detected by the target website, because your request seems to come from different geographical locations and IP addresses. This approach is more complicated, requires managing a pool of proxys, and may require additional logic to handle the rotation of proxys. Rotating proxy is suitable for situations that need long-term running, large-scale crawling or the target website has strict anti-crawling measures.

According to the search results, here are some suggestions for choosing an proxy:

The data center proxy is fast and has high performance, which is suitable for tasks that need to send a lot of requests and are not too worried about IP being blocked, but IP is easy to be detected and blacklisted.

Residential proxys use real residential IP, which is more difficult to detect. It is suitable for crawling activities that require high success rate and anonymity, but it is usually more expensive than data center proxys.

The mobile proxy uses the IP address assigned by the mobile network operator to the mobile device, which is suitable for use when a special mobile network is needed to grab the results, but the price is usually more expensive.

When choosing an proxy, you should also consider the following factors:

Anti-crawler strategy of target website: If the target website has strict anti-crawler measures, rotating proxy may be a better choice.

Project budget: Rotating proxy is usually more expensive than static proxy because it requires more proxy servers and more complicated management.

Scale and duration of data capture: For large-scale or long-term capture projects, rotating proxy may be more suitable because it can reduce the risk of IP being blocked.

Quality and reliability of proxy: No matter which type of proxy is selected, it is necessary to ensure the stability and speed of proxy server so as not to affect the crawling efficiency.

Generally speaking, if your crawling task requires high anonymity and low risk of blocking, rotating proxy is a better choice. If your requirements are simple and the anti-crawling measures of the target website are not strict, a static proxy may be enough.
