WordPress is a very useful and powerful CMS. But depending on the usage and settings, WordPress websites can be very slow, especially for those who are lack of skill.
If you want to increase the speed of your WordPress website, just follow the steps listed below:
- Convert the cache plugin to WP Fastest Cache (free) or paid.
- Enable all settings in WP Fastest Cache.
- Disable another image optimizer plugin, and install the Robin Image Optimizer plugin. Open the Robin Image Optimizer settings and press the “Run” button and perform bulk optimization. This plugin will do an optimization of all your pictures. Leave the tab open, so it's done.
- If you are not subscribing to any CDN packages, you can use WordPress CDN for your pictures for free. Go to the WP Fastest Cache settings, and navigate to the “CDN” tab. Click “CDN by Photon” and start integration with WordPress CDN by Photon. Now your pictures will be hosted on your own WordPress CDN. You can check by going to any of your posts, and see your image URL will change to “https://i0.wp.com/urlanda.com/wp-content/…/..jpg”.
- You can already check the speed of your site and see the changes.
- If you are using Google Font, install the OMGF plugin. Open the OMGF settings, and follow the instructions listed. Conduct a search on the font you use, select and download your font. Click “Generate Stylesheet” and allow “Remove Google Fonts”. Now your font has been optimized.
- Now open GTMetrix or Chrome Dev Tool, and make analysis for your site. Refer to the waterfall section to see if there are other things that cause your website to slow down.
The steps listed are not necessarily the best method. I’m just contributing my personal experience based on my previous trial for WordPress websites. Nevertheless, they are very effective and will not cause any damage towards their site. You can change or select any plugin that you feel suits your situation.
I choose Plugins that were based on the trials and tests towards some other plugins, but I didn't post my results here because there was too much data needed.
I will keep this guide up-to-date from time to time, as soon as I find a better way.
