A slow WordPress site costs visitors and affects your findability in Google. The main causes are often the same: no caching, overly large images, and a bloated plugin and database structure. By addressing these three points and ensuring hosting that’s tailored to them, significant speed gains are achievable without needing to code.
Enabling caching
Caching ensures that visitors see a stored version of your page, instead of WordPress rebuilding it on every visit. This is usually the fastest gain you can achieve.
Choose a caching solution
A plugin such as WP Super Cache or W3 Total Cache works at the software level. If your site runs on a LiteSpeed server, you can also use LSCache, which works at the server level and is usually faster than a plugin alone.
Enable browser caching
Set static files such as CSS, JavaScript, and images to remain stored locally with the visitor for a period of time. This way, the browser doesn’t have to fetch them again on every visit.
Exclude dynamic pages
Shopping carts, account pages, and forms often need to be excluded from caching, otherwise visitors will see outdated or incorrect data.
Optimizing images
Large, uncompressed images are a common cause of slow pages. Address this before uploading, not afterward.
- Compress images before uploading with a tool like TinyPNG or ImageOptim.
- Use the WebP format instead of JPEG or PNG where possible, with a fallback for older browsers.
- Responsive images let WordPress automatically serve the right file size per device.
- Lazy loading ensures images only load once a visitor scrolls to them.
Cleaning up plugins and database
Every plugin adds code that needs to be loaded, and a database full of old revisions, spam comments, and trash items slows down queries.
- Remove plugins you no longer use, rather than just deactivating them.
- Clean up the database periodically with a tool like WP-Optimize: remove revisions, spam, and trash.
- Minify CSS and JavaScript so files become smaller; many caching plugins do this automatically.
- Limit the number of plugins that load scripts on every page, even if you don’t need them everywhere.
In Plesk, the control panel used with Tandata’s web hosting, you can quickly see per site which resources are being used, which helps in identifying heavy plugins.
Hosting as a foundation
No matter how well your site is optimized, hosting determines the foundation. A server with NVMe storage reads and writes files significantly faster than a traditional hard drive, and a web server such as LiteSpeed processes requests more efficiently than standard Apache. If you’re considering switching, you can read on the switching to Tandata page how a migration works without downtime.
Frequently asked questions
How much faster will my site become after optimization?
That strongly depends on the starting situation. Caching and image optimization usually provide the biggest gains, especially if your site doesn’t yet apply either.
Is caching safe for a webshop?
Yes, as long as you exclude shopping cart and account pages from caching. Commonly used plugins do this automatically when they detect WooCommerce.
Which image format should I choose?
WebP is the best choice for most photos and illustrations in terms of file size and quality. Use PNG only for images with transparency.
How do I measure my current loading time?
Tools like Google PageSpeed Insights or GTmetrix give you insight into loading time and concrete recommendations. Test both desktop and mobile, as they often differ.
Does email hosting affect the speed of my site?
Not directly, but if email and website run on the same server, heavy load can affect each other. At Tandata, business email runs separately from your web hosting, which prevents this.
Conclusion
A faster WordPress site revolves around three pillars: enabling caching, optimizing images, and cleaning up plugins and database. Combine this with hosting set up accordingly, and you have a solid foundation for a fast, well-findable website.
