A slow website doesn't just frustrate visitors - it costs your charity rankings. Since 2021, Google has used Core Web Vitals as a ranking factor, which means page speed directly affects where you appear in search results. And for charities, where every visit could be a potential donor, volunteer, or beneficiary, the stakes are high.
The good news: many of the biggest speed improvements require no developer and no budget.
How Much Does Speed Actually Matter?
Google's own research shows that as page load time goes from 1 second to 3 seconds, the probability of a visitor bouncing increases by 32%. From 1 second to 5 seconds, that jumps to 90%. Charity websites - often built on aging CMS platforms, loaded with uncompressed images and outdated plugins - frequently fall into the 4-8 second range.
Test your site now: visit pagespeed.web.dev and enter your homepage URL. Google gives you a score out of 100 and a prioritised list of issues to fix.
What Google Actually Measures
Core Web Vitals are three specific metrics Google uses to assess page experience:
- Largest Contentful Paint (LCP): how long it takes for the main content of a page to load. Aim for under 2.5 seconds.
- Interaction to Next Paint (INP): how quickly your page responds when a user clicks or taps. Aim for under 200ms.
- Cumulative Layout Shift (CLS): how much the page jumps around as it loads. Aim for under 0.1.
Failing any of these won't cause an instant rankings collapse, but passing them gives you a small but real advantage over competitors who don't.
The Most Common Speed Problems on Charity Websites
Uncompressed images
This is the single biggest culprit on most charity websites. A photo uploaded directly from a camera or phone can be 3-8MB. The same image, properly compressed, should be 100-300KB with no visible quality loss. Multiply that across 10 images on a page and you've added 30-80MB of unnecessary load.
Fix it: use Squoosh (squoosh.app) - free, browser-based, no account needed. Compress every image before uploading. For images already on your site, download them, compress them, and re-upload.
Wrong image format
JPEG is fine for photos. PNG is better for logos and graphics with transparency. WebP is better than both and is now supported by all modern browsers. Converting your images to WebP typically reduces file size by a further 25-35% with no quality loss.
No image dimensions specified
When a browser doesn't know the size of an image before it loads, it can't reserve the right space on the page - causing layout shifts (CLS). Always add width and height attributes to your <img> tags.
Too many plugins (WordPress)
Every active WordPress plugin adds CSS and JavaScript that must load on every page, whether it's used on that page or not. Audit your plugins annually and deactivate anything you don't actively use. Ten unused plugins can add 1-2 seconds to load time.
No caching
Caching stores a version of your pages so they don't have to be rebuilt from scratch every time someone visits. Without caching, every pageview hits your server and database. On WordPress, plugins like WP Super Cache or W3 Total Cache are free and can dramatically reduce load times.
Render-blocking scripts
JavaScript files loaded in the <head> block the page from displaying until they've fully loaded. Adding defer or async to your script tags tells the browser to load them in the background instead. This is a developer change but often a quick one.

Quick Wins You Can Do Today
- Run your site through pagespeed.web.dev and note the top three opportunities
- Compress all images on your homepage using Squoosh
- Enable caching if you're on WordPress
- Check your hosting - shared hosting on a cheap plan is often the underlying cause of slow TTFB (time to first byte). Upgrading to a VPS or managed WordPress host can shave seconds off load time
What About Your Host?
No amount of image compression will overcome a genuinely slow hosting provider. If your server response time (TTFB) is consistently over 600ms, the problem is your host - not your code. For charity websites, managed WordPress hosting from providers like Kinsta, Flywheel, or even SiteGround's business plan offers significantly better performance than budget shared hosting.
Speed and Mobile
Google measures Core Web Vitals primarily on mobile. A site that loads in 2 seconds on a desktop may take 6 seconds on a mid-range Android phone on a 4G connection. Always test your mobile score separately in PageSpeed Insights - it's often significantly worse than desktop and should be your priority to fix.
Getting your charity website into the green on Core Web Vitals won't guarantee top rankings, but it removes a barrier that may be silently costing you visibility - and donors.
