Search Engine Crawler Agents: Simulating Real User Behavior to Avoid Detection

First, why is it easy to use proxy IP to do the crawler to be recognized?

Many friends who do data collection have had this experience: obviously using a proxy IP, the target site can still recognize the crawler behavior. This is becauseRegular proxy IPs are easily labeled as server room IPs by websitesThe website will not use this type of IP to access the website at all. When a website finds that an IP segment frequently accesses a specific page, it will directly trigger the anti-climbing mechanism.

For example, if a data center IP continuously accesses the product price page and triggers 50 requests in 10 minutes, the system will directly block the IP. at this time, if you switch to theReal Home Broadband IP (Residential IP), it will be able to effectively circumvent this detection. Like ipipgo provides global residential IP resources, directly from more than 90 million home networks, IP address and ordinary Internet users are identical, the site is difficult to distinguish between artificial or machine operation.

II. 4 key details of simulating real users

1. Request headers are randomly generated: Don't use a fixed browser logo, randomly switch User-Agent for each request, and it is recommended to cover different versions of Chrome, Firefox, Safari, and even simulate mobile access.

2. Irregular intervals between operations: Manual operation will have a click-browse-scroll pause, recommended settingsRandom delay between 3 seconds and 2 minutes, avoiding fixed frequency trigger thresholds.

3. IP switching policy optimization: Don't wait until the IP is blocked to change it, but adjust it dynamically according to the tolerance of the target site. Example:

4. Access Path Simulation: Don't visit the target page directly, open the home page of the website first, browse 2-3 other pages randomly, and then jump to the target link to simulate the real user path.

Third, how to use ipipgo to realize zero blocking collection?

ipipgo's residential IP library has two core strengths:
– High IP purity: Every IP is verified on the real home network and will not be flagged as a proxy!
– Geographically accurateSupport for IP selection by country, city and even carrier, especially suitable for scenarios that require localized data

Specific operational steps:
1. Create a project in the ipipgo backend and selectDynamic Residential IPparadigm
2. Set up IP switching rules (recommended to switch by number of requests)
3. Access to the API in the crawler code to automatically obtain a new IP address for each request.
4. Combining random User-Agent and mouse trajectory simulation

IV. Frequently Asked Questions QA

Q: How to choose between dynamic IP and static IP?
A: You need to choose dynamic IP for frequent switching (e.g., price monitoring) and static IP for long-term session maintenance (e.g., login status collection). ipipgo supports both modes, and the static IP can be retained for a maximum of 24 hours.

Q: What should I do if I encounter a CAPTCHA?
A: Check if the frequency limit is triggered first, it is recommended:
- Reduced request density for a single IP
- Increase page dwell time
- Prioritize US/European residential IPs (relatively lax anti-crawl strategy)

Q: Why do you recommend ipipgo?
A: Compared to traditional proxy services, ipipgo's90 million residential IP poolIP authenticity can be guaranteed, support socks5/http(s) all protocols, measured blocking rate is less than 0.3%. through the free trial function, developers can test the quality of IP before making decisions.

V. Real case: e-commerce price monitoring system

After a cross-border e-commerce team used ipipgo's dynamic residential IPs, the blocking rate dropped from 351 TP3T to 0.81 TP3T. their core strategy was:
- Collect only 5 product pages per IP
- Randomized 15-120 second interval between acquisitions
- Mixture of US, German and Japanese IPs
This program has been running stably for 11 months, with an average daily data collection of more than 200,000 items.

By doing the above, you'll realize that using the right proxy IP tool is just the first step.The key lies in the authenticity of the behavioral patterns. It is recommended to test different strategies with ipipgo's free resources first to find the most suitable collection solution for your target website.
