How to improve website speed?

Hello guy, I have a blog that is more than a year now but I don't usually post content and the blog is slow in loading. Is there any way that I can make it load fast?

Use light weight theme, limit the use of a lot of plugins, and try to use optimized images for improving website speed.

There are many ways to improve website speed, such as optimizing images, magnifying code, implementing caching, using a content delivery network, reducing server response time, enabling compression, and optimizing the code of your website. Additionally, optimizing your server and database, using a CDN for static assets, and reducing redirects can also help improve website speed.
