Web Scraping Tips on Avoiding Detection

Web scraping has become a necessity for businesses today since it allows judi bola you to quickly gather data that can be used for marketing purposes, trend analysis, and much more.

However, as web scraping has become more popular, website owners have become more aware of the practice and have begun to take steps to prevent it.

It means that those who wish to engage in web scraping must be increasingly careful to avoid detection. Below are some tips to avoid detection when scraping the web for business needs, such as competitor analysis or market research.

Possible Restrictions During Web Scraping

When you’re web scraping, you’re essentially using a script or program to extract data from a website. While most websites don’t explicitly forbid web scraping, they may have measures in place that make it difficult or impossible to do so. Here are some restrictions that might stop you from web scraping.


If a website detects that you’re scraping it, it may flag your IP address. It means that the website will block any further requests from your IP address.

To avoid being flagged, you can use a proxy server, which is a server that acts as an intermediary between you and the website you’re scraping.

IP Blocking

Some websites may go a step further and block your IP address entirely. This means that you won’t be able to access the website at all from your current IP address. To get around this, you can use a proxy server or a VPN (Virtual Private Network).

A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a test that is designed to determine whether or not the user is a human.

Many websites use CAPTCHAs as a way to prevent bots from scraping their content. You can use a CAPTCHA solver, which is a program that can automatically solve CAPTCHAs, to scrape websites with a CAPTCHA.


Blacklisting means that the website owner has specifically added your IP address to a list of addresses that are not allowed to access the website.

You’d experience this if the website owner has determined that you’re scraping the website.


The final resort for a website that doesn’t want to be scraped is to ban your IP address. You will no longer be able to access the website at all.

There’s not much you can do if you’re banned except using a different IP address.

5 Tips to Avoid Detection During Web Scraping

Since you don’t want to be detected as a web scraper, you need to take some steps to make your scraping activities more challenging to detect.

1. Use a Proxy

One of the best ways to avoid detection when web scraping is to route your requests through a proxy server. When you use a proxy, your IP address will be hidden, and it will appear as if the requests are coming from the proxy server instead of your computer.

There are many different proxy services available, so be sure to research to find one that is right for you. It’s best to use paid proxies from reliable proxy providers since they have dedicated support.

2. Use the Right Proxies

Residential proxies are the best type of proxies to use for web scraping since they are more difficult to detect. In addition, you can use residential proxies to rotate your IP address and make it appear as if you are coming from a different location.

Datacenter proxies are another type of proxy that can be used, but they are not as effective as residential proxies since they are easier to detect. However, they are much faster and cheaper.

3. Space Your Request Rate

If you make too many requests to a website in a short period, you will likely be detected as a web scraper. To avoid this, you should space out your requests to appear to be coming from a human instead of a bot.

You can do this by using a proxy pool and setting a request rate limit. Each IP address in the pool will only make a certain number of requests per minute.

4. Use a Headless Browser

A headless browser is a web browser that can make requests and process web pages without actually rendering the pages. Headless browsers are used for web scraping since they are much faster than traditional web browsers.

One of the benefits of using a headless browser is that it makes it more difficult for website owners to detect that you are a web scraper.

5. Rotate User Agents

When you send a request to a website, your user agent is sent along with the request. The user agent is a string of text that identifies the type of browser and operating system you are using.

Web scrapers often use the same user agent for all of their requests, which makes it easy for website owners to detect them. You should rotate your user agent with each request to avoid getting caught or banned by a website.

There are many different user agents to choose from, so be sure to select one that is appropriate for the website you are scraping.


Considering the importance of web scraping for business, it’s no wonder that website owners are taking steps to prevent it.

To avoid detection when web scraping, you need to take some precautions, such as using a proxy server, spacing out your request rate, and using a headless browser. You should also rotate your user agent with each request to make it more difficult for websites to detect you.
