Speed is a ranking factor. That's not optional information.

Google officially confirmed page speed as a ranking factor in 2010 for desktop and 2018 for mobile. Since then, they've expanded this into Core Web Vitals — a set of specific speed and user experience metrics that Google measures for every website and uses in its ranking algorithm.

For local businesses, this matters doubly. Most local searches happen on mobile devices. If your site loads slowly on a phone — and most WordPress sites do, without proper optimisation — Google is actively ranking you lower while also giving your visitors a bad first impression. You're losing on both fronts.

How to check your site's speed right now

Go to pagespeed.web.dev and enter your website URL. Run the test on mobile (the default tab). You'll get a score out of 100 and a breakdown of specific issues. A score below 50 is poor. 50–89 is needs improvement. 90+ is good. Most unoptimised small business WordPress sites score in the 20–50 range on mobile. That's a problem.

The report will list specific issues in priority order. The items labelled "Opportunities" have the most impact if fixed. The ones labelled "Diagnostics" are secondary.

The Core Web Vitals you need to know

Google measures three Core Web Vitals for every page:

  • Largest Contentful Paint (LCP) — how long it takes for the main content of the page to appear. Think of it as "when does the page actually look loaded?" Target: under 2.5 seconds.
  • Interaction to Next Paint (INP) — how quickly the page responds when someone taps or clicks something. Target: under 200ms.
  • Cumulative Layout Shift (CLS) — whether the page jumps around as it loads (buttons moving, text shifting). Target: under 0.1. Anyone who's gone to tap a button on a mobile page and accidentally hit something else because the layout shifted has experienced a high CLS score.

Why WordPress sites are often slow

WordPress is a powerful platform, but out of the box it's not optimised for speed. The most common culprits:

  • Unoptimised images — uploading a 4MB photo from your phone directly to WordPress. The page then loads that 4MB image on a 375px wide mobile screen. The image should be compressed and resized before upload, and served in WebP format.
  • Too many plugins — every active plugin adds code that loads on every page. Ten plugins all loading scripts and stylesheets adds up fast. Deactivate any plugin you don't actually need.
  • No caching — without a caching plugin, WordPress builds every page from scratch on every visit, querying the database each time. A caching plugin serves pre-built HTML, which is dramatically faster.
  • Slow hosting — shared hosting on a budget plan often means your site sits on a server with hundreds of other sites, competing for resources. Managed WordPress hosting (what Design Menu provides) puts your site on infrastructure tuned specifically for WordPress performance.
  • A bloated theme — some themes load dozens of files even when you're not using the features those files support. A leaner theme or a well-configured page builder reduces this.
  • No content delivery network (CDN) — a CDN serves your static files (images, CSS, fonts) from a server geographically close to the visitor. For BC visitors, a CDN with a Vancouver or Seattle node is faster than a server in Toronto or the US East Coast.

Quick wins you can do today

If you manage your own WordPress site, these changes have high impact and don't require a developer:

1
Install a caching plugin
WP Rocket (paid, worth it), W3 Total Cache, or WP Super Cache (both free). Enable it and use the default settings to start. This alone often improves PageSpeed scores by 20+ points.
2
Compress your images
Install ShortPixel or Imagify. These plugins automatically compress images you upload and can bulk-optimise your existing media library. Enable WebP conversion if your host supports it.
3
Audit and remove unused plugins
Go to Plugins → Installed Plugins. For each one, ask: am I actively using this? If not, deactivate and delete. Even deactivated plugins can slow admin performance — delete what you don't need.
4
Enable lazy loading for images
WordPress 5.5+ has native lazy loading for images. If your theme or page builder overrides this, a plugin like a3 Lazy Load can re-enable it. Lazy loading means images below the fold don't load until the user scrolls to them.

When to get help

Some speed issues require server-level configuration or theme-level changes that go beyond what plugin settings can fix. If you've implemented the quick wins above and your PageSpeed score on mobile is still under 60, it's worth having someone audit your specific setup.

Site speed is part of what gets addressed in Design Menu's managed hosting plans. Performance optimisation is ongoing — not a one-time checkbox. If your current host isn't prioritising it, that's a meaningful cost to your search visibility and customer experience.

The business case, simply: A 1-second improvement in mobile load time can increase conversions by 3–5%. For a local business getting 200 visitors a month, that's meaningful. Speed isn't a technical vanity metric — it's a revenue lever.
