This often manifests as a 403 Forbidden Error, indicating restricted access to the desired webpage. Understanding the cause and implementing effective solutions is key to successful web scraping. In this blog, we will look at how to fix when it is blocked.
Why URLs Get Blocked in Web Scraping
In order to stop automated bots from scraping material, which might cause server congestion or raise privacy issues, URLs are usually restricted. Websites use a variety of anti-scraping measures, such as IP restrictions and CAPTCHAs, to make it difficult for scrapers to obtain the needed data.
Understanding 403 Forbidden Errors

Top 8 Ways for Web Scraping without Getting Blocked
Web scrapers frequently utilize techniques like switching user agents, employing proxy servers, or using delay tactics between queries in order to get around URL bans. Every one of these techniques balances efficacy with moral web scraping strategies, offering pros and cons. The following five tactics should be tried in order to successfully scrape websites without getting blocked:
1. Use Proxies/ VPNs
VPNs and proxies are essential resources for getting around URL restrictions. By hiding the IP address of the scraper, they provide the impression that the queries are originating from various places. This approach has the potential to be very successful, but selecting trustworthy and moral proxy services like IPOasis is essential.
2. Automated Tools
Web scraping can be facilitated by a number of automated programs that are not prohibited. These technologies are made to resemble the browsing habits of humans in order to lessen the likelihood of being discovered and blocked.
3. Respect Robots.txt
Websites' robots.txt files list the sections that web spiders are not allowed to access. In addition to being in accordance with moral scraping techniques, according to these principles lessens the possibility of website administrators blocking you.
4. Leverage Headless Browsers
With headless browsers, you can replicate the surfing habits of an actual person more precisely. This might involve varying the patterns of clicks, scroll movements, and even typing mimicking. Compared to conventional scraping bots, websites are less likely to detect these advanced technologies.
5. Implement CAPTCHA
CAPTCHAs are a mechanism used by websites to prevent automated scraping programs. These obstacles may be overcome by integrating CAPTCHA solving technologies into your scraping plan. You may use CAPTCHA solution services—both automatic and manual—into your scraping procedure.
6. Implementing Fake User Agents
One common reason for scraping blocks is the use of default or scraper-identifiable user agents. Configuring your scraper to mimic real browser user agents can effectively disguise your scraping activities, making your requests appear as coming from legitimate users.
7. Employing Rotating Proxies
For large-scale scraping operations, using a single IP address can quickly lead to blocks.

8. Optimizing Request Headers
Beyond user agents, ensuring your HTTP request headers closely resemble those sent by real browsers is crucial. This involves adjusting headers like Accept, Accept-Language, and ensuring consistency with the chosen user agent.
