Following links from one page to another helps these crawlers gather data and provide it to search engines, enabling users to find relevant content. 

How Does a Web Crawler Work?

It discovers URLs, follows internal links, and collects content from websites. 

As it navigates through the web, the crawler indexes the gathered information and sends it to the database, enabling search engines to provide accurate and relevant results to users. 

This process allows you to understand how web crawlers systematically gather and organize data, ultimately influencing the search results that users encounter.

3. Monitor Traffic

Monitor your site’s traffic regularly. Use analytics tools to identify unusual crawling patterns or spikes in bot activity. 

If you spot suspicious behavior, investigate and take action promptly.

4. Deploy Web Application Firewall

Consider using a web application firewall (WAF). This tool can help you filter out malicious traffic and protect against common attack vectors.

5. Keep Software Updated

Regularly update your content management system (CMS) and plugins. Outdated software can be vulnerable to exploitation by malicious crawlers.

6. Implement Rate Limiting

Rate limiting on your server will prevents bots from overwhelming your site with requests, ensuring legitimate users can access your content.

7. Set Honeypot Traps
