To improve security, the script could include input sanitization and validate the URLs being scraped. This would prevent potential vulnerabilities if user input is passed directly to the script, ensuring that only valid, whitelisted domains are processed. Additionally, adding SSL verification for requests would enhance security when accessing HTTPS sites.

Adding functionality to scrape additional categories or pages dynamically would make the script more versatile. This can be achieved by extracting links to other sections and visiting them recursively.
