every developer must take when developing a web scraper that doesn't get banned or blocked by the website they are trying to scrape is to set a fake user-agent with every request.</p> <p>Because, by

browser headers over just fake user-agents makes your scrapers requests harder to detect, and as a result, your scrapers more reliable.</p></div></div> <p>For simple websites, simply setting an up-to-date user-agent should allow you to scrape a website pretty reliably.</p> <p>However, a lot of popular websites are increasingly using sophisticated anti-bot technologies to try and prevent developer from scraping data from their websites.</p> <p>These anti-bot solutions not only look at your requests user-agent when analysing the request, but also the other headers a real browser normally sends.</p> <p>By using a full set of browser headers you make your requests look more like real user requests, and as a result harder to detect.</p> <p>The fake browser header API returns the following headers in every header set:</p> <ul> <li>Accept</li> <li>Accept-Encoding</li> <li>Accept-Language</li> <li>User-Agent</li> <li>Sec-Ch-Ua</li> <li>Sec-Ch-Ua-Platform</li> <li>Sec-Fetch-Site</li> <li>Sec-Fetch-Mode</li> <li>Sec-Fetch-User</li> </ul> <p>For more information on how anti-bot technologies use header fingerprints to detect scrapers then <a
