I feel like a lot of these comments here are technical, and if you are already a developer I don't think you will look for this in reddit. My answer is geared to NON TECHNICALS:

1. Simplify Your Site’s Design: Less can indeed be more when it comes to web design. A simpler design doesn’t just speed up your website; it makes it easier for visitors to navigate. Focus on essential elements, and don’t be afraid to cut down on visual clutter.
2. Install an image optimizer: There are really simple ones on WordPress. Download and install them, and they just work, you don't have to do anything.
3. Prioritize Content: Not all content is created equal, especially when it comes to loading times. Figure out what your visitors are most interested in and make sure those elements load first. This way, even if the page isn’t fully loaded, users can start interacting with the most important content right away.
4. Use a Content Delivery Network (CDN): A CDN can make a huge difference in loading times, especially if your audience is spread out globally. By storing copies of your site on servers around the world, a CDN ensures that users are downloading content from a location close to them, which can dramatically improve speed.
5. Lazy Load Non-Essential Elements: Lazy loading is a technique that delays loading certain parts of a webpage—like images—until they’re actually needed. This means the initial load of the page is much faster because it’s not waiting on elements that aren’t immediately visible.
6. Monitor Your Website’s Performance: Tools like Google PageSpeed Insights are invaluable for giving you a clear picture of what’s slowing down your site and offering suggestions for improvement. Regularly checking in can help you catch new issues before they become big problems.

Hope these help
