What is the solution to preventing data collection on websites?

When using crawler tools for data collection, it is often faced with the problem of website blocking access. Websites often adopt anti-crawling mechanisms that restrict crawlers' access and even block visitors' IP. This poses a challenge for data collection, so how can we solve this problem?

1. Follow the rules of the target website

When collecting data, we must comply with the rules of the target website to ensure that it does not impose undue pressure on access. Crawlers usually retrieve a large amount of data at a specific point in time, which can cause the performance of the target website to degrade or even affect the normal access of other users. Therefore, reasonable adjustment of crawl speed is the first step to solve this problem, which not only helps protect the normal operation of the website, but also avoids our IP being blocked.

Why do travel aggregation platforms need to use IP agents?

Ensure reasonable grab speed

In order to avoid adverse effects on the target website, we need to reasonably adjust the crawling speed according to the load capacity of the website and the frequency of access. Too frequent requests will put great pressure on the website server, affecting its response speed, and may even cause the server to crash. Therefore, we should test and adjust the speed according to the reaction speed of the website, access restrictions, and server load.

Protect IP from blocking

Not only to protect the normal operation of the target website, but also to prevent their IP from being blocked by the website. Requests that are too frequent may be recognized by the website as malicious crawlers, resulting in the IP being blocked and the target website not being able to be accessed again. With a reasonable crawl speed, we can avoid requesting websites too often, reduce the risk of being blocked, and ensure that we have continuous access to the data we need.

2. Use alternate proxy IP addresses

When conducting data collection, using a single IP to perform crawl requests on multiple websites or access multiple pages at the same time is easy to be identified as crawling behavior by the target website, resulting in IP blocking. To mitigate this risk, it is wise to choose an agency that allows automatic IP rotation. Constantly changing IP can make our access more insidious, which is crucial for large-scale data collection. Rotating proxy IP can not only bypass the restrictions of the website, but also distribute the access pressure and improve the success rate of data collection.

What are the advantages of residential agents over data center agents?

Maintain IP privacy

One of the main purposes of rotating proxy IP is to maintain IP stealth, making our access look more like normal user behavior. Frequent visits to websites using the same IP in a short period of time are easily identified by websites as crawlers, triggering anti-crawler mechanisms that restrict our access. By automatically rotating IP, we are able to use different IP addresses for different access, reducing the probability of being identified, protecting our IP from being blocked, and ensuring that data collection is ongoing.

Improve the success rate of data acquisition

Another important benefit is the increased success rate of data collection. Different websites have different restrictions on the frequency of visits and the amount of data, and too frequent visits may lead to data collection failures. Using a rotating proxy IP, we can distribute access requests rationally and avoid a large number of requests to the same website in a short period of time, thus reducing the risk of being blocked. At the same time, rotating proxy IP can also disperse the access pressure, improve the efficiency of simultaneous collection of multiple target websites, and improve the success rate of data collection.

3. Adopt a variety of crawling modes

Websites can determine whether a visitor is a robot through IP browsing patterns, so they need to adopt a variety of crawling modes. Setting up a pattern to access random links on the page makes the visit more like normal user behavior, increasing the stealth of the crawler. Using a variety of crawling modes can not only reduce the probability of being identified as a crawler, but also improve the efficiency of data collection.

To deal with the problem of website blocking data collection requires a combination of the above solutions. Use rotating proxy IP to reduce the risk of being blocked; Use a variety of crawling modes to increase stealth. Through reasonable strategies and technical means, we can effectively solve the problem of website preventing data collection, and achieve the purpose of obtaining the required data efficiently and stably.
