Why are crawler browsers always blocked? Maybe you're missing this layer of protection
Engage in data collection friends understand, the most headache is just run up the program, the target site will pop up the verification code. What's worse is that the account is blocked collectively, and the number that was raised for half a month before is all ruined. In fact, most cases are not code problems, but yournetwork fingerprintExposed.
Now the website wind control system thieves, not only look at the IP address, will also detect the browser resolution, time zone, font dozens of features. Just like you go to the supermarket always wear the same clothes, the cashier wants not to remember you are difficult. This time we have to rely on proxy IP + fingerprint camouflage to play with the war, ipipgo's dynamic residential proxy just to solve this problem.
Three Steps to Browser Incognito
1. IP pools have to be like chameleonsThe ipipgo residential proxy covers 200+ countries and automatically switches to the real home broadband IP for each request. for example, when collecting e-commerce data, use the US IP to check the 3C products, and cut to the German IP to look at the small home appliances, which is more than 10 times safer than using the fixed IP.
2. Don't be lazy with your fingerprint disguise: Type `navigator.plugins` in the browser developer tools to see your plugin information. It is recommended to randomly generate the following parameters when using a headless browser:
- User-Agent (don't use the default HeadlessChrome)
- Screen resolution (don't always use 1920×1080)
- Time zone setting (to match IP location)

|---|---|
| Canvas Fingerprint | Inject random noise |
| WebGL rendering | Modifying Graphics Card Parameters |
| Font List | Delete special fonts |
3. Account segregation should be thorough: Never log into multiple accounts under the same IP! Use ipipgo'ssession hold functionFor example, if you are a cross-border e-commerce company, you can use New York IP for your American store and Osaka IP for your Japanese store, so that the platform can't see the relevance at all.
A practical guide to avoiding the pit
Recently, a friend who does overseas crowdfunding stepped on a big mine: obviously used a proxy IP, 10 accounts or a pot. I helped him investigate and found three problems:
- Browser fingerprints haven't been changed completely, all accounts are in Beijing time.
- IP switching intervals are too regular, changing every 5 minutes instead of being flagged
- Used unreliable proxy service provider, slow API response leads to timeout
After switching to ipipgo's smart rotation mode, set theRandom switching interval(30-180 seconds), with the browser automation tool to modify the hardware fingerprints, now more than half a year accounts are steady as old dogs.
QA time
Q: Can't I just use a free proxy? Why should I buy a paid service?
A: free proxy 99% is molecular play left, IP has long been the major platforms to pull black. ipipgo's IP pool is updated quarterly 60%, to ensure the availability of more than 98%.
Q: Does fingerprint camouflage affect browser speed?
A: As long as you don't open too many plug-ins, measured with ipipgo's socks5 proxy + basic camouflage, the page loading speed is only slowed down by about 0.3 seconds. Compared to the risk of being blocked, this delay is nothing at all.
Q: How to assign IPs for running multiple crawler projects at the same time?
A: Create multiple sub-accounts in ipipgo backend and set independent IP whitelist for each project. For example, project A only uses Brazilian IP, project B only uses Southeast Asian IP, and the traffic bill is also counted separately.
At the end of the day, being a crawler and running an account is like playing hide and seek. Bothbe able to hide(anonymity) and againbe fast(Stability). Since using ipipgo's residential proxy, our team no longer has to get up in the middle of the night to deal with CAPTCHA. Now the success rate of registering new accounts has soared from 37% to 89%, saving enough cost of sealing to buy three years of proxy service.
