Your site is slow. Do you know how much money you lose every second?
One second. That’s how long it takes to blink. It’s also the one second too many that can cost you a customer.
The research is clear:
- 40% of visitors leave a site if it takes more than 3 seconds to load.
- A single second of delay can cut conversions by 7%.
- Google penalises slow sites in its search results.
A slow WordPress site isn’t just a technical annoyance. It’s revenue bleeding away. It’s a bad first impression that ruins your credibility. It’s a major brake on your growth.
The good news? Speed isn’t down to fate. It’s a science. At BLACKT, performance optimisation is at the heart of every WordPress site we build. Here are 10 tips, from the simplest to the most technical, to give your site a fresh boost.
Tip 1: choose a good host (the foundation of everything)
This is tip number zero. If your hosting is poor quality (often very cheap shared hosting plans), you can optimise everything you like and your site will still be slow. It’s like trying to run a TGV (France’s high-speed train) on wooden rails. Choose a host that specialises in WordPress (such as Kinsta, WP Engine, o2switch…) and offers optimised servers.
Tip 2: optimise your images (culprit number one)
Oversized images are the main cause of slow websites. The rule is simple:
- Resize your images to the exact size at which they’ll be displayed. There’s no need for a 4000px-wide image shown at 800px.
- Compress them with a tool such as TinyPNG or Imagify before uploading them.
- Use the WebP format, which is much lighter than JPEG or PNG.
Tip 3: install a caching plugin (the turbo)
A cache is a “pre-loaded” version of your page that is served to visitors. Instead of WordPress rebuilding the page on every visit, it serves a static copy, which is much faster. It’s the most effective optimisation there is.
Recommended plugins: WP Rocket (paid, but the best), W3 Total Cache, WP Super Cache.
Tip 4: clear out your plugins
Every plugin you add puts an extra load on your site. Audit your plugins:
- Which ones are truly essential?
- Are there plugins you no longer use? Deactivate and delete them.
- Are there plugins that do the same job twice?
Fewer plugins = a lighter, faster site.
Tip 5: use a lightweight, well-coded theme
Some WordPress themes are bloated monsters, packed with features you’ll never use that slow your site down. Go for themes known for being lightweight with clean code (such as GeneratePress, Astra, or a well-built custom theme).
Tip 6: update PHP
PHP is the programming language WordPress runs on. Each new version is significantly faster than the last. Make sure your host uses a recent version of PHP (8.0 or later). It’s an instant, free performance gain.
Tip 7: clean up your database
Over time, your database builds up a lot of “rubbish”: post revisions, spam comments, temporary data… A plugin such as WP-Optimize can clean all of that up and make your database more responsive.
Tip 8: use a CDN (content delivery network)
A CDN is a network of servers spread around the world that store a copy of your site. When a visitor arrives, they’re served by the server closest to them. The result: shorter loading times, especially if you have an international audience.
Recommended services: Cloudflare (a very effective free plan), RocketCDN.
Tip 9: disable pingbacks and trackbacks
These are WordPress features that notify other blogs when you link to them (and vice versa). It’s an outdated feature that wastes resources for nothing. You can disable them under Settings > Discussion.
Tip 10: limit external scripts
The Google Analytics tracking script, the Facebook pixel, live chat, Google Fonts… Every external script you add is a call to another server that can slow yours down. Keep only the ones that are absolutely essential to your business.
FAQ: WordPress speed and performance
Q1: how do I measure my site’s speed?
Use tools such as Google PageSpeed Insights, GTmetrix or Pingdom. Don’t focus only on the score, but on key metrics such as LCP (Largest Contentful Paint), which measures how long it takes to display the largest element.
Q2: what is the ideal loading time?
Under 2 seconds is an excellent target. Between 2 and 3 seconds is acceptable. Beyond 3 seconds, you start losing visitors and being penalised by Google.
Q3: I’ve optimised everything but my site is still slow. Why?
It’s probably your hosting. If the foundations (the server) aren’t sound, you’ll never be able to build a fast house. It’s the first thing to check.
Q4: does a page builder like Elementor slow my site down?
Yes, by its nature a page builder adds code and can slow a site down compared with a custom-coded theme. However, with good optimisation (hosting, caching, images…), it’s entirely possible to have a very fast Elementor site. That’s our speciality at BLACKT.
Q5: I know nothing about this. Can you help?
Of course. Performance optimisation is an integral part of our maintenance contracts. We can run a full audit of your site and put in place every optimisation needed to get it back up to cruising speed.
