- 12. What to Consider
- 13. Start Testing • https://developers.google.com/speed/pagespeed/insights • http://tools.pingdom.com/fpt/ • http://www.webpagetest.org/ • http://gtmetrix.com/ (is particularly harsh)
- 14. Clean Up Your Database • BACKUP FIRST • In phpMyAdmin:
- 15. Do You Really Need That Plugin? • Delete any plugins you’re not using • Dump anything that isn’t updated regularly • Avoid plugins that create queries on the fly when a flat file would do
- 16. Use Browser Caching • Set an expiry date in your HTTP headers for static resources • For example: Expires: Thu, 07 Nov 2022 23:00:00 GMT • More: https://developers.google.com/speed/docs/best-practices/caching#LeverageBrowserCaching
- 17. Minimize HTTP Requests • If you’re not using a plugin on a specific page type, see if you can avoid loading it • Do you really need social icons everywhere? • Move JS to server-side PHP if possible
- 18. Optimize Your Images • Don’t upload an image larger than what’s required • Use the right file format for the job – PNGs are awesome – GIFs are for tiny images or animation – JPGs are for photographs • Use an image compressor – WP Smush.it plugin
- 19. Compress/Combine JS + CSS
- 20. Use Sprites • Every time an image request is made, a kitten cries • http://spriteme.org/
