I. Why is your crawler always recognized?
Do data collection friends understand, the most headache is just run two minutes on the blocked IP. you think add a random delay can pretend to be like a real person? Now the website wind control system is a thief, can pass theMore than 20 dimensionsDetermine whether the traffic is real or fake. Let's say that a normal person using a cell phone to swipe through a web page will not have an IP address that jumps from Beijing to New York in five minutes; nor will a machine send requests at precise cardinal points every second.
Here's a misconception to correct: a lot of people think that if they use a proxy IP, they can rest easy. In factIP qualityrespond in singingUsageThat's the key. Last year we tested, with ordinary agent pool for commodity price monitoring, survival time is less than 15 minutes on average. Then we switched to ipipgo's dynamic residential agent, and the survival time directly tripled.
II. Three axes of real-life behavioral simulation
The first move: add drama to the IP
Don't treat IPs as disposable props. It is recommended that each IP complete at least10-20 operational processesAnd then switch. For example, first visit the home page → click on the category → view details page → simulate scrolling → add to the collection, this set of actions to complete the same IP. ipipgo's session hold function is particularly suitable for this scenario, to ensure that the whole set of operations IP remains unchanged.
Tip #2: Make Time Noise
Don't use fixed intervals! Real people browse the web with thinking pauses. Try this formula:
Base interval = random (3-8 seconds) + page load time x 1.5
Automatically generated if load time exceeds 5 secondsFalse scroll event, simulating user waiting behavior.
| Type of operation | Recommended duration |
|---|---|
| jump to a new page | 8-15 seconds |
| Form Filling | 20-40 seconds |
| Image Loading | 3-6 seconds with random scrolling |
Tip #3: Device Fingerprinting Smorgasbord
Don't underestimate browser fingerprinting detection. We have done experiments: with 50 proxy IPs but the same device profile, it was blocked in 10 minutes. It is recommended to match ipipgo'sTerminal Fingerprinting ServiceThe IPs are automatically generated with different browser versions, screen resolutions, and font combinations, so that each IP carries a unique device signature. Ever seen an IP pool at 3am? Switching strategies have to be adjusted for different times of the day: - Morning peak (9-11am): use city-level IPs with switching intervals of 30-60 minutes Here's the kicker.Failure Retry MechanismThis is more in line with the logic of a real person encountering the problem. Q: Why do I still get blocked after using a proxy? Q: How can I tell if the IP quality is good or bad? Q: Do I need to maintain my own IP pool? One last rant: don't be enamored of the so-called perfect solution. Last week we had a customer use our API and put in the request header"User-Agent: ipipgoBestProxy"This honeyed operation results in a second block. Remember, the core of camouflage isReasonable in the midst of chaos, rather than deliberate perfection.III. Hidden techniques for IP switching
- Late night (0-5pm): upper provincial IP pools, surviving longer
- Special dates (Double 11/Black Friday): turn on ipipgo'semergency expansion modeAutomatic replenishment of triple IP reservesIV. Practical QA First Aid Kit
A: Check three points: 1. Whether cookie persistence is on 2. Whether the IP's geographic jump is reasonable 3. Whether you have the correct SSL fingerprints with you
A: Look at these three metrics in the ipipgo backend:
- First request success rate >92%
- Average response time <800ms
- 24-hour survival rate >75%
A: Unless the team has a dedicated operator, it is recommended to use ipipgo's hosting service directly. They automatically eliminate 15% low-quality IPs every day, which saves a lot of effort compared to manual maintenance.
