6 Golden WordPress Tips

  2. Keep plugins lightweight
    Too many unnecessary plugins slow down your site; use code snippets instead when possible.

  3. Backup before adding new code
    A quick backup ensures you can restore your site instantly if something goes wrong.

  4. Use proper code formatting
    Well-formatted code is easier to debug, reduces errors, and helps you quickly identify issues in your functions.

  5. Test snippets in staging first
    Always test new code in a staging or local environment to avoid breaking your live website.
