The internet has proven to be an essential factor needed for the growth of businesses over the last decade. Though this sounds like a sure way to progress as a business, it takes skill to unleash the internet’s full potential. Getting your hands on data can assist you in making very critical decisions to grow your business. Thus, you have to be up to date with anti-scraping technology.
Website owners invest thousands in anti-bot technology to prevent hacking, DDoS attacks, and other malicious activities on their sites. However, these protections can’t distinguish between benign web scraping and more sinister intents, blocking it all the same.
That sounds like a bummer, right? Well, there is no need to worry. Like always, I am here to assist internet users with all the help they need to get going. In this article, I will talk about anti-scraping technology and how to bypass it.

What Is Web Scraping?
As its name suggests, web scraping is when we extract data from the internet. Web scraping gathers readable data from across one or multiple sites. This is done by sending requests using bots and storing the data received. This data, which is usually messy, then needs to be parsed into user-friendly formats like PDFs and spreadsheets.
It is worth mentioning that it is possible to scrape a website manually. However, using scraping tools to automate the process is quicker and more effective. Imagine how long it would take to scrape hundreds of websites manually.

Why Is Web Scraping Important?
In today’s digital economy, every business must make use of every tool available to gain an advantage over the thousands of competitors they face in their industries. Let’s take a look at some of the benefits of web scraping.
Industry Insights and Analytics
Data in the modern world is an invaluable commodity. Due to this, scrapers gather all the data they can get to build massive databases containing statistics and insights from various industries. These databases may include prices of certain products, like oil, which helps companies make vital decisions to gain an edge over their competitors.
Price Comparison
No one would like to pay more for a product when they can get the same product at a cheaper price somewhere else. It is common today to see comparison websites where you can check the prices of products from various retailers. This enables buyers to get the best bang for each buck they spend. This is possible thanks to web scraping.
Lead Generation
It is common these days for companies in the B2B space to post their business information online. By using scraping technology, businesses can easily find potential clients by scraping for contact information on the net.

What Is Anti-Scraping Technology?
Web scraping is very beneficial to businesses. However, as I pointed out earlier, website owners invest vast amounts of money in preventing the use of bots on their sites.
Anti-bot technology makes it difficult to extract data from a website. To do this, the website must recognize and block requests from alleged bots and other malicious users.

How To Bypass Anti-Scraping Technology
Anti-scraping technologies and techniques have evolved over the years and keep on changing. Today, many websites use tools that can detect when a bot sends requests by analyzing the user’s behavior. This, coupled with other anti-bot techniques, makes web scraping difficult, if not impossible.
However, like most problems in the world, there is always a solution. Let’s take a look at how we can bypass anti-scraping technologies deployed on various websites.
Make Use of Rotating IPs
Your IP address will be flagged as suspicious if you send too many requests within a short period. This could result in your IP being blocked. Otherwise, your bots will be forced to fill out a CAPTCHA to prove that a real human is behind the request.
To avoid this, you can set up your scraping bot with rotating residential proxies. This allows you to automatically change your IP address to any random residential IP address. This makes it difficult for anti-bot mechanisms to detect your activities. Because each request is sent from a different IP address, it is seen as a request from different users.
Residential proxies are the best choice here because, unlike data center proxies that are sourced from data centers, these are IPs of real devices. As far as anti-bot technologies are concerned, these legitimate IPs look like regular users. Meanwhile, if they notice a data center IP, they will suspect bot activity.
Change Scraping Pattern
No matter how skilled a human is, it is impossible to repeat the same action with the same precision hundreds of times in a row. Bots, on the other hand, are programmed to do the same thing over and over again. Therefore, your bot can be easily spotted if it performs identical actions anytime it sends a request to the website.
You can, however, prevent this by programming your bot to simulate human activity. Incorporating random clicks and mouse movements can make your bot appear as a real human user rather than a machine. You can also make use of common referrers like Facebook, YouTube, or Google to appear as authentic traffic that has been redirected to the site.
Do Not Scrap Too Fast
Web scrapers can send hundreds of requests within a very short time. However, this makes it easy for anti-bot technologies to detect and block their activity.
To overcome this issue, you can reduce the speed at which your bot searches the internet. You can also factor in random, periodic sleep times to mimic an actual human user. No human being can send as many requests as a bot could within any set period.
User Agent Rotation
Whenever you send a request to a website, the server receives information about you in the form of a ‘user agent.’ This information tells the server the exact web browser where the request is coming from, among other things. Anti-bot technology can find your digital fingerprint suspect and ban you as soon as it detects inhuman activity.
As such, creating a list of user agents and randomly rotating between them for each request is advisable. You can also set your user agent to a common web browser instead of your actual user agent.

Frequently Asked Questions
Q1. What is anti-bot technology?
Anti-bot technology is designed to detect and block automated bots from accessing websites, APIs, or online services. It’s commonly used to prevent web scraping, fraud, and spam.
An anti-bot system monitors website traffic and analyzes patterns to determine if a visitor is a human or a bot. If it detects suspicious behavior, it can block access, challenge the request with a CAPTCHA, or limit functionality.
Common Anti-Scraping Techniques:
- Rate limiting restricts how many requests can be made from a single IP in a short time.
- CAPTCHAs force users to complete a challenge that bots can’t easily solve.
- JavaScript challenges require browsers to execute JavaScript, something many bots can’t do.
- Behavior analysis tracks mouse movements, clicks, and scrolling to distinguish humans from bots.
- IP & fingerprint blocking flags suspicious IP addresses or browser fingerprints used for scraping.
Websites implement anti-scraping measures to protect data, prevent competitors from collecting pricing info, and secure user privacy. While some bots serve legitimate purposes, anti-bot technology ensures that harmful or unauthorized bots don’t disrupt services.
Q2. Is visibility: hidden better than display: none?
Whether display: none or visibility: hidden is better depends on what you’re trying to achieve.
display: nonecompletely removes the element from the layout, meaning it won’t take up space on the page.visibility: hiddenkeeps the element in the layout but makes it invisible.
When to Use Each One:
- For Regular Design & UX:
- Use
display: noneif you want to remove an element entirely. - Use
visibility: hiddenif you want to hide something but keep the space it occupies.
- Use
- For SEO & Bots (Anti-Scraping Techniques):
- Many headless browsers (used by scrapers and bots) can still detect elements hidden with
visibility: hidden, but they may ignore elements removed withdisplay: none. - Some sites use honeypot traps, where they add hidden form fields (e.g., using
display: none) to catch bots that fill in fields meant to be invisible to humans.
- Many headless browsers (used by scrapers and bots) can still detect elements hidden with
If you want an element to fully disappear, go with display: none. If you need it to stay in the layout but be invisible, use visibility: hidden. When dealing with headless browsers or honeypot traps, display: none is generally better for hiding elements from bots.
Q3. What is HTTP scraping?
HTTP scraping is the process of using automated scripts or bots to extract data from websites by sending HTTP requests and parsing the responses. This method allows you to retrieve structured or unstructured data, such as product prices, news articles, or social media posts.
How It Works:
- Sending HTTP Requests. The scraper mimics a web browser by sending requests to a website using HTTP methods like GET or POST.
- Customizing HTTP Headers. To avoid detection, scrapers modify HTTP headers like
User-Agent,Referer, andCookiesto make the requests appear as if they’re coming from a real user. - Handling IP Rotation. Websites track and block repeated requests from the same IP address. Using IP rotation with rotating proxies helps disguise the scraper by changing the IP address periodically, reducing the risk of being blocked.
Why It’s Used:
- Market research and price comparison
- SEO monitoring and keyword tracking
- Aggregating content from multiple sources
By managing HTTP headers properly and using rotating proxies for IP rotation, HTTP scraping can be done efficiently while minimizing the chances of detection.
