How to avoid IP blocking for e-commerce price monitoring?
The biggest headache of doing e-commerce price monitoring is the anti-crawl mechanism of the target website. Ordinary users with fixed IP continuous access, less than half an hour will be recognized as a crawler. We tested a mainstream e-commerce platform, a single IP continuous request 30 times after the trigger CAPTCHA, 50 times directly banned for 24 hours.
That's when it's time toResidential Proxy IPto simulate real user access. For example, using ipipgo'sDynamic Residential IP PoolThe platform sees the access records of ordinary home broadband from all over the world, just like real consumers are comparing prices, effectively reducing the risk of being blocked.
Three steps to build the core architecture of the monitoring system
1. Data Acquisition Module: Use Python's Requests library in conjunction with a random request header, set at random intervals of 3-8 seconds. The point is that each request must be associated with a new proxy IP.
2. Agent Dispatch Hub: It is recommended to call ipipgo's API directly to get the latest available IPs. theirIntelligent Routing TechnologyIt can automatically match the neighboring nodes where the target web server is located, and the measured response speed can be increased by more than 40%.
3. verification mechanism: Deploy double checking - first use Head requests to check page reachability, then perform a full data crawl. IP failure is found to be marked immediately to avoid repeated use of dead IPs.

Three Tips for Capturing the Real World
Tip #1: Time-Sharing Capture Strategy - Split the monitoring task into morning, midday, and evening executions with ipipgo'sArea Orientation FunctionThe IPs of different provinces are used to simulate the browsing habits of real users.
Tip 2: Anomalous Traffic Filtering - Deploy traffic cleaning on the proxy server side to automatically filter malicious IPs that have been flagged by websites. ipipgo'sReal-time health detection systemThe IP blacklist is updated every 15 minutes and the effective availability rate is kept above 95%.
Tip 3: Data de-duplication mechanisms - Do timestamp comparison on the collected price data to avoid duplicate storage. It is recommended to set a 5-minute data update frequency to ensure timeliness without triggering anti-climbing rules.
Frequently Asked Questions
Q: How to deal with CAPTCHA encountered during collection?
A:Prioritize checking proxy IP quality, suggest switching to ipipgo's high stash of residential IPs. meanwhile, reduce the collection frequency and increase the mouse movement track parameter in the request header.
Q: What if the same product shows different prices in different regions?
A: This is exactly why proxy IPs are needed. Through ipipgo'sCity-level positioning functionsIt allows you to simultaneously collect quotes from 20 major cities, including North, South and South China, to get real regional pricing strategies.
Q: Is there a significant drop in the success rate of nighttime collection?
A: Nightly maintenance by some proxy IP providers results in lower availability. ipipgo uses theGlobal Node Load Balancingtechnology, the measured 24-hour availability fluctuates no more than 3%, and the evening peak still maintains a success rate of more than 92%.
