1. Optimize images

Images are one of the most important components of any website. Images help users understand what they’re looking at and make them feel comfortable browsing around your site. If your images aren't optimized properly, they could slow down loading times and cause your page to load slower than it should. To optimize images, use a free online tool called TinyPNG.com. Simply upload your image and click “optimize” to get a preview of how much space your image takes up after optimization. You can then download the optimized version of your image directly from TinyPNG.com, saving yourself time and bandwidth.

2. Use caching plugins

Caching plugins store static content (like CSS files) on your server so that if someone visits your site again, their browser won't have to go back to the web host's servers to retrieve the file. Caching plugins work best when combined with CDNs (content delivery networks), which cache static content on remote servers instead of storing it locally. There are many different types of caching plugins out there, including WP Super Cache, W3 Total Cache, and Cloudflare Workers.

3. Add compression to your images

Compressing images before uploading them to your site saves space and makes your pages load faster. Compression works by reducing the amount of data stored in each picture, making it smaller and easier for your visitors' browsers to handle. There are several ways to compress images, including using a plugin like JPGMini.com, optimizing your images with TinyPNG.com, or compressing your own images with Photoshop or GIMP.

4. Reduce JavaScript usage

JavaScript is a programming language that runs inside your browser. While it can add functionality to your website, it can also slow down your site. By reducing the number of scripts you're running, you'll speed up your site. One way to do this is to use a script manager like Google Tag Manager. Another option is to use a service like NoScript.org, which blocks third-party scripts entirely.

5. Remove unused code

Unused code slows down your site. When you remove unused code, you reduce the size of your site and improve performance. Unused code includes comments, HTML tags, and inline styles. You can find unused code by opening your site's source code in a text editor and removing everything except for the actual code.

6. Keep your theme updated

Updating your theme regularly keeps your site secure and helps prevent bugs from being introduced. Many themes offer automatic updates, but you can manually update your theme by downloading the latest version from its developer's website.

7. Use a CDN

A Content Delivery Network (CDN) stores copies of your site's static content on remote servers across the internet. Using a CDN means that your visitors don't need to wait for your site to load before viewing your content. A CDN also helps keep your site safe from hackers by distributing your site's files across many servers. There are many different CDNs available, including Amazon S3, MaxCDN, and Cloudflare.
