Web scraping technique is the technique from which we can scrape data from multiple sites automatically. Other websites detect automated data scraping through their mechanisms which block the computer ID. But there are various problems that you can face during data extraction from websites, and that is the blockage of your computer IP by the server, which denies your access to load the web page.
So, to avoid getting blocked or blocked from your target websites to scrape data, ProxyCrawl can be very helpful for you. You can use an intelligent rotating proxies pool to get the IP address refreshed automatically. You can customize the auto rotation according to your suitable timing, which helps the data scraping professionals. In this article, we will discuss a detailed overview of how to?scrape data anonymously.
Top Techniques to Anonymously Scrape Data:
- Focus On Website Dynamic Layouts - Some websites use dynamic layouts to make them ticklish for the website scrapers. For instance, 1 to 8 pages of a website display a different layout, and the rest exhibit something else. That's why you need to focus on whether the layout is the same or has changed. If the changes are present, you need to change your scraping method by adding different conditions to your code to extract those pages.
- Use Different Crawling Patterns - For data extraction, try to use different crawling patterns. As we humans browse other websites randomly, the bots to scrape data are programmed in a similar crawling pattern except if identified. The websites that use the intelligent anti-crawling mechanism can quickly identify spiders by detecting the patterns in their activities, which can cause blockage. Try to include random clicks on the website pages, mouse movements, and irregular actions that make a spider look human.
- Routing of HTTP Header Requests and User Agents - A server has a "user-agent" tool that tells the server about web browsers' usage. You cannot view the content from the websites until the user-agent is set. A web browser's requests contain a user-agent header and can detect a bot using the same user-agent. You can quickly get your user-agent by searching it through the google search bar. If you want to make your user agent seem more realistic and easily bypass the detection, you have to fake your user agent.?You have to add your user-agent by yourself as most website scrapers do not have the user-agent by default. So. When you send your user-agent alone, it will easily pass through the most initial bot detection tools and scripts. If somehow, your bots are getting blocked despite putting a current user-agent string, add more requests headers and then try again.
- Using Browsers Like Selenium, Puppeteer, or Playwright - When the methods mentioned above are not working well, the website confirms whether you are a real browser. The easy way to check is if a web browser can render the JavaScript block. If it is, then it is a real browser. If it doesn't, then it means it is a bot. In the browser, it is possible to block JavaScript. Most of the websites become unusable in that situation, and because of this, JavaScript is enabled in most browsers. In that way, it is essential to use a real browser for data scraping purposes. In most cases, a real browser is required to scrape data. The libraries that automatically control the browsers are as follows;
- Playwright
- Selenium
- Puppeteer
With time, such anti-scraping tools have become more brilliant as bots feed vast amounts of data to AIs to identify them. Recent?scrape?data Bot Mitigation Services utilize bot detection of client-side in intelligent techniques and not just depend on to check whether you can execute JavaScript.
The primary things that the bot detection tool checks are whether you manage your browser in actuality or an automated library run it.
- The signatures specified by Bots are present or not
- Supports the features of the browser that are nonstandard
- The appearance of Puppeteer, Selenium, or Playwright automation tools
- Arbitrary mouse movement, scrolls, multiple different clicks, continuous tab changes, etc.
These are the different ways to check whether a bot or a human manages the browser.
Some tools that help your headless browsers from getting blocked or blocked;
- Phantom JS –?A custom manipulated JavaScript API to utilize Chrome driver’s capabilities.
- Fingerprint Rotation –?Fingerprint Rotation on Microsoft Paper
- Puppeteer Extra –?Puppeteer Stealth Plugin
Bot companies are also getting more competent and the bots as they have significantly been ameliorating the Artificial Intelligence models. Focusing on events, variables, and actions is also helpful in giving the presence of an automated library that may cause data scraping blocked.
- Be Cautious About Honey Pot Traps - The systems used to track or detect any hacking attempts through hackers or other means to get your personal and sensitive information are called Honeypots. This application emulates similar ways as an entire system. Sometimes, the honeypots installed by websites are invisible to ordinary users yet seen by web scrapers.? These links have good clarity, while those Honeypot links used to detect spiders have the CSS style or are similar to the page's background color to get invisible. The process of detecting Honeypot traps is not an easy task. It requires a significant amount of time and knowledge of programming to do it properly. That's why this technique is not used commonly, either by the bot or the server-side.
- Ignore Data Extraction Behind a Login - The permission that is required to get access to the website pages is known as login. In comparison, some websites allow permission, and some don't. If the website page has a login form, the web data scraper must send some information with each request to visit the website page. In this way, it is easy for the targeted website to analyze the coming requests from a similar address, and they can become cautious and deny your demands and the blockage of your account. As a result, you have lost your time and efforts by being blocked. Hence, it is recommended not to use those websites to scrape data purposes protected by login as it is easy for you to get detected and blocked from those targeted websites. Hence, one thing you can do is to emulate human browsers whensoever corroborate is needed; you can get the required data you need.
- Try to Extract Data Slowly and Not to Overburden the Server with Continuous Requests - The bots used for website data scraping are usually really quick, yet as humans cannot browse that fast, the website can easily detect your data scraper. So, it may be risky for you to crawl faster. If the website receives a lot of requests simultaneously, it can be difficult for the website to handle them at once, and as a result, it will become unresponsive.? Try to make your spider real like human actions. Do not load it with multiple requests and try to put some intervals and delays between the requests to crawl the desired pages of the websites. By using the auto throttling mechanism, you can automatically throttle the speed of the requests based on the load of the website that you want to scrape data. Adjust its crawling speed smoothly and periodically according to the changes of the environment as it may change over time.
- Using reCAPTCHA - The websites that use anti website scraping measures, and if you are scraping a website on a large scale, the particular website will eventually block or block you. Suddenly, different captcha pages start to appear instead of website pages. These services use to restrict like 2Captcha. When you want to scrape websites on a large scale and use captcha, try to use captcha services. These services are beneficial and are relatively cheap.
How Websites Track Activities To Scrape Data By Anonymous Sources?
Websites using multiple mechanisms can detect spiders from a regular user. Some of the methods are as follows;
- Heavy Website Traffic Than Usual - It contains?particularly from those IP addresses or single users within a short period.
- Similar Browsing Patterns for Repetitive Tasks - It?depends on the supposition that repetitive tasks cannot perform by the human user/client.
- CAPTCHAS And reCAPTCHAS - The checks to attempt and execute JavaScript. It can further check your CPUs and Graphic cards to ensure that you are not a bot or a server but an actual human.
- Detection through honeypots? - The honeypot traps are those links that are invisible to ordinary users but only visible to the spider. Whenever the spiders try to access those links, these spiders are captured.
Concluding Remarks
I hope this article helps you a lot in understanding data scraping anonymously. You can either choose a Proxy service or VPN service to perform web data scraping anonymously. But it would be best if you consider the legal aspects of web data scraping. So, firstly, try to read the terms and conditions page of the website that you want to scrape. If not, then move on to the purchased one.
As my suggestion,?ProxyCrawl?is the best one to use for data scraping anonymously without getting detected or blocked. But, you have to use free trial first as free trials offer most services, and you will get an idea of whether your requirements are fulfilled or not.
