How to Make Your Website Load Even Faster
Even with a lightweight theme, there are several other optimizations you should implement:

Your hosting plays a huge role in website speed. Choose a provider with fast servers, SSD storage, and built-in caching. Best Hosting for Speed:
- SiteGround – Visit Site
- Kinsta – Visit Site
- Cloudways – Visit Site
2. Optimize Images (Reduce Size Without Quality Loss)
Images can slow down your website if they’re too large. Use modern formats like WebP instead of PNG or JPG.
Best tools:

3. Use a Content Delivery Network (CDN)
A CDN stores copies of your website’s static content in multiple locations worldwide, reducing load times. Best CDNs:

Caching reduces the load on your server by serving static files to visitors. Best caching plugins:

5. Enable GZIP Compression
GZIP compression reduces file sizes, making your website load faster. You can enable this in your hosting panel or with the WP-Optimize plugin.
6. Minimize CSS & JavaScript Files
Too many CSS & JS files can slow down your site. Minify and combine them using: Best tools:

7. Use an SSL Certificate for Security & Speed
SSL certificates encrypt user data and help with SEO ranking. You can get FREE SSL from Cloudflare or your hosting provider.
