Non-Technical Guide On How To Speed Up WordPress

Speeding up your WordPress site doesn’t have to be a stressful, technical mess. Simple actions like optimising images, enabling caching and choosing the right plugins can have a noticeable impact, and none of them require you to write a single line of code.

Why You Need to Speed Up Your WordPress Website

Speed is critical to your site’s performance for several key reasons:

• Visitors don’t wait. Most people won’t wait more than a few seconds for a site to load. If your WordPress site is slow, visitors may bounce before your homepage even appears, meaning fewer readers, customers or leads.
• Search rankings drop with slow load times. Google takes loading speed seriously. Sites that load faster tend to rank better, which directly influences where your pages show up in search results.
• User experience improves instantly. A fast website keeps people engaged. Pages that load smoothly create a better browsing experience, especially on mobile.
• Conversions increase on faster sites. Every second counts for purchases, sign-ups or downloads. Online shoppers are quick to abandon carts on slow websites.
• Your reputation is on the line. A sluggish site creates a poor impression, while a faster site comes across as more professional and trustworthy.

How to Speed Up a WordPress Site Without Technical Knowledge

Choose a Fast and Reliable Hosting Provider

Your hosting choice sets the foundation. Shared hosting may be cheap, but it often struggles with high-traffic or plugin-heavy setups. Switching to managed WordPress hosting can speed up your website without much effort. Look for hosts that offer built-in caching, SSD storage and data centres close to your audience.

Use a Lightweight Theme

Heavy themes packed with flashy animations or complex layouts often slow things down. Instead, choose a lightweight, well-coded theme built for performance. Themes like GeneratePress, Astra and Neve are known for helping users achieve faster load times without extra effort.

Delete Unused Plugins and Media Files

Unused plugins still consume space and can affect your site’s performance. It’s a good idea to audit your plugin list and remove anything you’re no longer using. Large media files also slow things down, especially if they’re not optimised.

Update WordPress Core, Plugins and Themes

Outdated software can cause performance issues and even security risks. Keeping everything updated ensures you’re running the latest and most efficient codebase. Updates often include optimisations that improve performance.

Use a WordPress Plugin to Speed Up Site Performance

Adding a trusted WordPress plugin designed for performance, such as caching or image compression, can make a big difference with just a few clicks.

Ways to Speed Up a WordPress Site Using Plugins

1. Install a Caching Plugin

Caching stores a version of your site so it doesn’t have to reload from scratch each time.

• Go to your WordPress dashboard
• Click on Plugins, then Add New
• Search for LiteSpeed Cache, WP Super Cache or W3 Total Cache
• Install and activate one (all are free)
• Use the plugin’s default settings if unsure; they’re optimised for beginners

2. Compress Images Automatically

Large image files often slow down your pages. A plugin can handle this in the background.

• Install and activate Smush, ShortPixel or Optimole
• Choose automatic compression during the upload
• Use lazy loading to delay loading images that aren’t in view

3. Use a Database Optimisation Plugin

Over time, your site’s database collects junk such as revisions, spam comments and transients. Cleaning it up helps improve performance.

• Install WP-Optimize or Advanced Database Cleaner
• Run a cleanup for drafts, spam and post revisions
• Set up weekly or monthly automatic cleanups

4. Enable Lazy Loading for Videos and Images

Lazy loading delays the loading of off-screen elements, helping your site feel faster right away.

• Use a3 Lazy Load or enable the feature in Smush
• Activate image and video lazy loading options
• Test pages after activation to ensure nothing breaks

5. Use a CDN (Content Delivery Network) Plugin

A CDN loads your site from servers closer to your visitor’s location, reducing latency.

• Install the Jetpack, Cloudflare or Bunny CDN plugin
• Follow the plugin’s setup wizard to connect to the CDN
• Use automatic cache purging and file compression settings

6. Combine and Minify CSS and JavaScript

Reducing file size helps pages load faster. Minifying CSS and JS removes unnecessary characters from your code.

• Install Autoptimize
• Enable “Optimize JavaScript Code” and “Optimize CSS Code”
• Clear your cache after applying the settings

What to Avoid When Trying to Speed Up WordPress

Installing Too Many Plugins

It’s tempting to keep adding plugins for every little task, but too many can do more harm than good. Each plugin adds extra code for your site to load. Stick to only what you need.

Using Heavy Page Builders Without Optimisation

Visual builders like Elementor and WPBakery make design easier, but often load unnecessary scripts and styles. If you’re using one, pair it with a plugin like Asset CleanUp to unload files on pages where they’re not needed.

Ignoring Mobile Optimisation

Your site might load fast on a desktop but crawl on mobile. Use tools like Google PageSpeed Insights to check mobile performance specifically. Use responsive themes, compress mobile images and avoid large pop-ups.

Skipping Regular Speed Tests

You can’t fix what you don’t measure. Tools like GTmetrix and Pingdom show how your site is doing in real time. Run a test before and after using any plugin.

Using Unreliable Hosting

Even with all the right plugins, a slow server will keep dragging your site down. Choosing a decent hosting provider is often the fastest way to improve performance without changing anything else.

How to Test Your WordPress Site Speed

1. Use Google PageSpeed Insights

Google PageSpeed Insights is one of the most reliable tools for measuring page load speed. It provides a detailed breakdown of speed on both desktop and mobile, along with recommendations for improvement. Enter your website URL, click Analyze, then focus on the “Opportunities” section for tips on what can still be optimised.

2. Run Tests on Multiple Devices and Browsers

Sometimes site speed varies depending on the device or browser. What works perfectly on a desktop may not be the same on mobile or in browsers like Safari, Firefox and Chrome. Test desktop and mobile separately, use GTmetrix to see performance across devices, and use BrowserStack or CrossBrowserTesting for more detailed cross-browser insights.

3. Use GTmetrix for a Comprehensive Report

GTmetrix gives a full report on your WordPress site’s performance and identifies issues like slow loading scripts, uncompressed files and caching problems. Enter your URL, click Test your site, and analyse the results. GTmetrix also provides a waterfall chart showing how each resource on your page loads.

4. Monitor Speed Regularly

Site speed isn’t a one-time fix. It’s an ongoing process. Set up monthly or weekly speed tests, track performance after major updates or new plugins, and use a tool like Pingdom to catch any dips before they affect your visitors.

5. Avoid Relying on Just One Tool

Every speed testing tool measures slightly differently, and results can vary depending on server load or geographic location. Run tests with Google PageSpeed Insights, GTmetrix and Pingdom, compare results, and focus on recurring issues, as these usually indicate the most critical areas to address.

What Your Speed Score Actually Means

Running the test is the easy part. The report comes back with a number out of 100, a row of coloured bars and a list of warnings, and nothing tells you which of those you are supposed to act on. Here is the short version: the big number at the top is the least important thing on the page.

Lab data and field data are not the same thing

That score out of 100 is a simulation. Google loads your page once, on a throttled connection, on a mid-range phone it is pretending to be, and grades what happened. It is useful for finding problems, but it is not a measurement of what your visitors experienced.

Underneath it, if your site gets enough traffic, is a panel headed Discover what your real users are experiencing. That is field data, collected from actual Chrome users over the previous 28 days, and it is the part Google uses when it judges your page experience. When the two disagree, believe the field data.

The four numbers worth knowing

Three of these are Core Web Vitals. The fourth, time to first byte, is not one, but it is the number that points most directly at your hosting.

One thing worth knowing if you last read about this a couple of years ago: INP replaced FID as a Core Web Vital in March 2024, so any advice still talking about first input delay is out of date.

What to do about each one, without touching code

• LCP is slow. Nine times out of ten it is one oversized image. Find the largest thing above the fold, compress it, and check it is not being lazy loaded. Lazy loading your hero image delays the very thing this metric measures, which is a common own goal after installing an optimisation plugin.
• INP is slow. Something is running too much JavaScript, and on a WordPress site that is almost always a plugin. Deactivate them one at a time, retesting after each, and you will usually find the culprit inside twenty minutes.
• CLS is high. Something is loading late and shoving the rest of the page down: an ad slot, a cookie banner, a web font, or an image with no width and height set. Fix the image dimensions first, it is the most common cause and the easiest.
• TTFB is slow. This one is not really yours to fix. It is the server deciding how quickly to answer, and no plugin changes that.

That last point is worth sitting with. You can compress every image, strip every plugin and still be stuck at two seconds if the server is overloaded, because none of those things happen until the server has replied. If TTFB is the number letting you down, the rest of this article will not move it much, and the honest answer is that you have outgrown your plan or your provider. We have written separately about the signs it is time to change host.

One last habit worth building: always test while logged out. The WordPress admin bar bypasses most caching, so a test run while you are signed in tells you very little about what an ordinary visitor gets.

How Often Should You Optimise Your WordPress Site for Speed?

1. Monthly Check-ins Help You Catch What Slows Things Down

A lot can change in just a few weeks. Maybe your image gallery grew, or a theme update loaded some new scripts. Monthly speed checks help you spot small issues before they turn into full-blown performance problems. Pick a tool you’re comfortable with, run your homepage through it, and look at the waterfall view or load time.

2. Run a Speed Test After Every Major Change

Not all updates are equal. Some edits won’t impact performance much, but others can absolutely slow down your site. Test your site speed right after you install a new plugin, switch to a different theme, add video backgrounds or large sliders, or migrate to a new host.

3. Pay Extra Attention During Promotions or Traffic Peaks

Planning a holiday sale, launching a product or pushing out a newsletter? Those are high-traffic moments, and exactly when a slow-loading site can cost you the most. Do a round of optimisation ahead of any campaign: compress those images, trim unused plugins, and cache the pages that will get the most visits.

4. Build Speed Optimisation Into Your Routine

The easiest way to stay on top of speed is to treat it like any other maintenance task. If you already have a checklist for updating plugins, writing posts or backing up your site, just add a speed check to that list.
