In today's highly competitive business environment, access to online information is crucial for companies to gain a competitive advantage. Web scraping has become an efficient means for enterprises to quickly extract data from various channels to support the development of advanced business and marketing strategies.

However, despite the many benefits of web scraping, inappropriate operations may result in being blocked from the target website. Therefore, this article will share some practical ways to circumvent Google crawl block.

How to circumvent Google crawl block

Learn about web scraping

First, let’s clarify the concept of web scraping. Simply put, web scraping is the process of extracting publicly available material from websites. While this task can be done manually, in order to increase efficiency, many individuals and companies choose to use automated tools, such as web crawlers, to perform this task.

Why do we need to crawl?

Google is the world's largest information resource library, which contains a large amount of valuable data, including market trends, customer feedback, etc. Therefore, by doing scraping, businesses are able to obtain this data and formulate business strategies based on it.

Here are some common ways businesses use Google crawlers to obtain data:

•Competitor analysis and tracking

•Sentiment analysis

•Market research and potential customer development

However, to successfully Google crawl, you need to avoid being blocked. Here are some ways to circumvent the blockade:

1. Rotate IP addresses

Frequently sending requests using the same IP address may be considered unusual activity, resulting in being blocked. Therefore, it is recommended to use a proxy service to rotate IP addresses to simulate the behavior of multiple users, thus reducing the risk of being blocked.

2. Use a headless browser

Some websites detect requests from automated programs by examining the browser environment. To avoid this, use a headless browser, which does not display a graphical user interface and makes it more difficult to detect by websites.

3. Solve the verification code

Some websites will pop up a verification code when visiting to confirm whether the visitor is a real person. To automate this process, you can use a CAPTCHA solving service to help you solve CAPTCHAs and avoid being blocked.

4. Control crawling speed

Excessively fast crawling speed may alert the target website and lead to blocking. Therefore, it is recommended to control the crawl speed and add random delays between requests to simulate real user behavior.

5. Avoid image grabbing

Images are often objects that take a long time to load, and grabbing an image isn't always necessary. Therefore, it is recommended to avoid capturing images as much as possible to improve capture efficiency.

6. Use Google Cache

Finally, you can try to extract data from Google cache instead of visiting the target website directly. This avoids direct interaction with the target website and reduces the risk of being blocked.

Conclusion

Web scraping provides a powerful tool for businesses to obtain data, but to maintain scraping efficiency over the long term, they need to avoid being blocked. You can ensure smooth crawling by using some methods to circumvent blocking.
