Hi, to get better website performance, there are a few things you can do after you finish your website.
CDN – Cloudflare: (It’s the most important thing for a better performance). Most of the Hosting Services have an easy way to enable CDN, for or sites we use A2Hosting ( https://www.a2hosting.com?aid=601d93569e434&bid=75dbf1c0 ) and Cloudflare, the tutorial is available in this link: https://www.a2hosting.com/blog/enable-cloudflare/ – https://www.cloudflare.com/ – For other hosts: https://developers.cloudflare.com/learning-paths/get-started/
Browser Cache: Page load times can be significantly improved by asking visitors to save and reuse the files included in your website. – https://gtmetrix.com/leverage-browser-caching.html / https://gtmetrix.com/serve-static-assets-with-an-efficient-cache-policy.html#how-to-cache
Hosting Plan: It’s not recommended to use a low-cost common hosting plan. Select a fast hosting service. A2Hosting – https://www.a2hosting.com?aid=601d93569e434&bid=75dbf1c0
Compress and Combine Assets: For example, there are several different ways to compress and combine the assets, this is probably the easiest way: http://www.okler.net/forums/topic/minify-php-how-to-combine-minify-and-cache-javascript-and-css-files-on-demand/
Optimize Your Images: The images can also be improved, consider to export them in a lower quality. JPG 80% is good enough. – https://tinypng.com/
