Booking Site Crawl: Real-Time Monitoring of Hotel and Airline Pricing Changes

The Proxy IP Playbook for Price Monitoring

Recently, there are always doing travel booking friends asked me, how to real-time stare at dozens of platforms of the hotel offer. Today, I'm going to nag some dry goods with you and teach you how to use theproxy IPPlaying around with price monitoring, especially ouripipgoThe unique use of the

Why do you have to be on an agent to do data properly?

The first thing you need to do is to take your computer to the booking site, and in less than half an hour you will be blocked from the IP. last year, a buddy did not believe in evil, and used his own network to check the price of air tickets 80 times in a row, and then the next day, the account was pulled directly from the platform. Here to teach you three life-saving techniques:
① Different exit IP for each request（Don't use those free proxies, they die fast.)
② Controlling the tempo of requests（Don't go crazy like a pile driver.)
③ Disguise normal users(Remember to bring your browser fingerprints)

Real-world Capture Configuration Handbook

Here's a real usable configuration scenario (using ipipgo as an example):

Here's the kicker.Geographic selectionThe pit: a Cheng site for Jiangsu, Zhejiang and Shanghai IP to give a cheaper price, with Guangdong IP to check the same hotel may be expensive 50 dollars. This time you have to use ipipgo'sCity-level positioningfunction, specializing in catching proxy IPs in Shanghai and Hangzhou.

Avoiding the wild ways of backcrawling

Now the platform have learned to be more sophisticated, just change the IP is not enough to see. Here to reveal a few tricks:
1. Randomize mouse trajectory(Don't move in a straight line)
2. Simulation of manual stays(Wait 3-5 seconds after the page loads before operating)
3. Type of mixing equipment(Don't use the Windows computer's UserAgent all the time.)
4. Grabbing data in the early hours of the morning(Controls are much looser from 1-5 a.m.)

Special note: with ipipgo'sLong-lasting static IPWhen doing so, remember to change the IP segments every week. A previous user used the same IP for 30 days in a row and ended up being flagged by the platform as a crawler IP bank.

Case 1: Xiao Wang set up 20 requests per minute, and as a result the proxy IP cost skyrocketed. The problem was not doingRequests for de-duplication, the same hotel checked over and over again can actually be cached for 5 minutes.

Case 2: Old Zhang thought that buying the most expensive proxy would be stable, but it turned out that using a New York IP to check domestic hotels triggered CAPTCHA instead. In this case, you should choose ipipgoDomestic BGP lineThe delay can be compressed to less than 80ms.
