Best Practices

Drupal is the same as any other web site: there's best practices that are necessary to implement. Check out this list of best practices for Drupal, divided between General and Security:
General
- Keep all components up to date (Drupal core, themes, modules, etc.)
- Make sure user permissions are set correctly to prevent unauthorized access.
- Make regular backups of your site to prevent loss of data.
- Plan out how you want your site to look before creating it.
- Include metadata (such as descriptions and keywords) to enhance SEO on your site.
Security
- Consider applying security modules to prevent spam or hacks, such as CAPTCHA or 2FA.
- Stick with modules that have Drupal's seal of approval in order to prevent vulnerabilities within your platform.
