Yet, it can be useful to browse and do the job a bit slowly. Since it’s important how quickly someone browses the site, and thus, it’s important to simulate human behavior. That is, one should have delays done at random. Also, it would be a good idea to add some randomized clicks.
2. Avoid being blocked again
Once you simulate human behavior as described above, you may avoid being blocked. This is not an ultimate solution that helps not to be detected and blocked by the site. Whenever one enters the site, it starts to monitor their actions, including various details like browser type, version, device, and so on.
When such actions are not detected, the site will spot or refer to all this as bot actions. Writing some various user agents, those actions on the site is a great trick so as not to be detected and blocked. Another good idea is not to have older versions of the browsers, as they can seem suspicious and be vulnerable to be blocked.
3. Build a Web Crawler

There are several options you can use as a referrer. The most common is to use Google. Besides, when indicating Google, one may add a country domain showing where the site is being accessed.
5. Avoid Honeypot Traps
Honeypot Traps are the HTML links that users won’t detect but can still be accessible with a web scraper. This trap is enabled by the CSS selector, which controls human-related activities and thus may block scrapers easily.
Before scraping any site, it’s essential to be sure whether the site has such traps. To avoid these traps, one may apply a feature of web scrapers known as Selenium. It can render the page intended for scraping and check the page.
The idea of scraping the sites to get the required information can be problematic as some sites will try to avoid, detect, and block such attempts. So, not to be the victim of these sites, one needs to follow the great tips described above.
