Why are crawlers always blocked? You may have overlooked the importance of proxy IP
Many developers find that the target site obviously did not change the rules, but the crawler suddenly failed. In fact, all 80% bans stem from theFixed IP High Frequency Access. When the same IP continuously requests data in a short period of time, the server will immediately trigger the anti-climbing mechanism. We have tested: using a local IP to continuously crawl e-commerce site product information, on average 15 minutes to be blocked.
This is where a proxy IP is needed to solve the problem. The problem is solved bydistributed IP resource pool, allowing each request to use a different network address can effectively reduce the risk of being blocked. For example, ipipgo provides a residential IP service that realistically simulates the online behavior of individual users, making data collection closer to natural traffic.
Dynamic IP or Static IP, choosing the wrong type can backfire
Dynamic IP is suitable for scenarios that require frequent switching, such as second data capture. Static IP is suitable for operations that require session continuity, such as data capture after login. Here is a practical tip:Use a static IP for login and switch to a dynamic IP for data capture., both to ensure that the login status is valid and to avoid triggering frequency limitations.
As an example, ipipgo's dynamic residential IP pool supportsToggle on requestmaybetiming switchTwo modes. The developer can set the IP to change automatically every 10 requests, or switch to a new IP at a fixed time every day. this flexibility is especially suitable for crawler projects that need to run stably over a long period of time.
Hands-on tips for switching IP pools intelligently
Simply switching IPs isn't enough, it needs to be coupled with a smart strategy to maximize results. Three key points are shared here:
1. Stepped request intervals: 2 seconds between first visits, reduced to 0.5 seconds for consecutive successes, and automatically extended to 5 seconds for CAPTCHA encounters
2. IP quality grading mechanism: Mark responsive IPs as premium, prioritize their use and extend their duration of use
3. Abnormal Flow Fuse: When an IP triggers verification 3 times in a row, stop using it immediately and add it to the blacklist for 12 hours.
All of these features are directly configurable in ipipgo's API management backend, and they provideAutomated IP Healthiness Inspection SystemThe IP pool is always available, ensuring that failed nodes are eliminated in real time.
Four Advanced Strategies for Breaking the Counter-Climb
1. Hybrid Protocol Support: Using both HTTP and SOCKS5 proxies, some scenarios switch protocols to bypass specific detections.
2. Geographic precision movement: Prioritize the use of residential IPs in the same city when collecting local websites to reduce the probability of being detected.
3. Request feature randomization: Synchronize User-Agent and Header information each time you change IPs
4. Failed request retry mechanism: Automatically change IP and retry 3 times for requests that return 503/403 status codes.
These methods work in conjunction with ipipgo's90 million + residential IP resourcesThe use of the effect is remarkable. Their IP covers more than 240 regions around the world, which is especially suitable for projects that need to simulate multi-location user scenarios.
Frequently Asked Questions QA
Q: What should I do if my speed slows down after using a proxy IP?
A: It is recommended to turn on ipipgo'sIntelligent Route Optimizationfunction, the system will automatically select the node with the lowest latency. Also check if HTTPS protocol is enabled, encrypted transmission will slightly increase the time consuming.
Q: How to check whether the proxy IP is effective?
A: Add an IP verification link in the code, visit https://api.ipipgo.com/checkip before each request and compare the returned IP address to see if it has changed. It is recommended to perform automatic verification every hour.
Q: What do I do if I encounter Cloudflare validation?
A: Immediately stop the use of the current IP and switch to a residential IP with higher anonymity. ipipgoEnterprise Residential IP PoolAfter special processing, it can effectively reduce the probability of triggering human verification.
Q: Do I need to maintain the proxy IP myself?
A: When using a professional service provider like ipipgo, theirAutomated Operations and Maintenance System (AOMS)The IP pool will be updated in real time. Developers only need to get the latest available IP through the API and do not need to maintain the resource pool by themselves.
