Google Shopping Search API: A Legitimate Way to Get Real-Time Price Comparison Data

How to Grab Google Shopping Comparison Data? Try this wild trick

The e-commerce business all know that real-time price comparison data is money. But with Google shopping search API directly grab the data, minutes to be blocked IP, this time to rely on proxy IP to play guerrilla warfare. To cite a chestnut, last year a cross-border friends, with ordinary IP can only check 50 products per hour, changed to dynamic proxy IP directly to 2000 times / hour, the key is the freshness of the data can be controlled within 5 minutes.

Why do you have to use a proxy IP?

Google's API is like a gatekeeper, remember your IP to lock the number of visits. Ordinary users may feel that 500 times a day is enough, but to do the price comparison system, this amount of stuffed teeth are not enough. This time we have to playIP Rotation Tactics::

• ① Single IP request limit 50 times/hour
• ② Change new IP for every 30 requests.
• (iii) It can be increased to 80 times/hour in the early morning hours (less pressure on Google's servers).

Tested with ipipgo's residential proxy, it ran for 72 hours without being blocked, and the success rate stayed above 98%. This is much more stable than using a data center IP, after all, the residential IP looks more like a real person operation.

Hands-on with APIs!

这里说个骚操作：把代理IP和请求结合起来用。比如这样配置：

pay attention toMixing IPs from different geographic locationsFor example, the West Coast IP with New York time zone, do not let Google find the time zone does not match. ipipgo's IP library comes with geographic location camouflage function, can automatically match the time zone this point is very worrying.

Summary of common pitfalls

Q: Why is it still blocked after using a proxy?
A: 80% of the IP purity issues, do not use cheap shared IP. ipipgo is recommended to use ipipgo's exclusive residential IP, each IP is only used once thrown back to the pool, pro-measurement of the blocking rate can be reduced to below 2%.

Q：数据太高怎么破？
A：重点看代理服务器的响应速度，别光看带宽。ipipgo的欧美节点控制在200ms内，比某些标榜高带宽的实在多了

Q: How much IP volume do I need to prepare?
A: There is a formula to estimate:
Number of IPs required per hour = Total requests ÷ (Single IP limit x 0.8)
For example, to do 5000 times / hour, single IP cap 50 times, then you have to prepare at least 125 IP. ipipgo's pool stock is large enough to temporarily increase the amount of not afraid of no inventory.

Why do you recommend ipipgo?

This one's a killer.IP recovery mechanismThe IPs used once will not be re-assigned for 24 hours, which is safer than their counterparts' 72-hour recycling cycle. Last time I tested it, I found that they can actually assign IPs accurately down to the city level, which is especially useful for doing regional comparisons.

There's also a hidden feature thatProtocol artifacts, can disguise API requests as normal browser traffic. Although there is an extra charge, the loss is much smaller than being blocked by Google. The most critical is the fast response of customer service, the last time I encountered a technical problem at 3:00 a.m., I actually received a solution in 10 minutes.

Engage in data capture is like a guerrilla, the right tool is twice the effort with half the effort. Don't key in the IP quality search, sealing a delay in business enough to buy half a year agent. Remember three points: rotation to be diligent, position to be mixed, speed to be stable, the rest is to sit and collect data.
