Compass Clinic: a real website performance case study

Compass Clinic is a psychological and support services practice, and we've been their ongoing WordPress maintenance provider for a while now. This isn't a "we built this from scratch" story. It's the more common, less glamorous kind of project: an existing WordPress site that had been running for years and needed a real performance audit.

What we found

PageSpeed Insights scored the homepage 62 on desktop and 57 on mobile, solid enough that nothing looked obviously broken, but slow enough to be costing real visitors. Part of the cause was almost comically simple: the site's logo was being served at 878×370 pixels to display at 93×39, nearly 20 times larger than it needed to be, on every single page load. There was also a NitroPack caching plugin installed and fully disconnected from its account, doing nothing but taking up space, plus unconsolidated Google Fonts requests and an unused popup plugin still loading its scripts on every page.

Fixing it, without a rebuild

None of this needed a new site. It needed the existing one fixed properly:

• Swapped the oversized logo for a correctly sized image variant instead of forcing every visitor's browser to download and shrink a 4x-too-large file.
• Deactivated the disconnected NitroPack plugin, which was adding overhead with no caching benefit behind it.
• Consolidated Google Fonts requests and deferred third-party scripts so the page could render before waiting on them.
• Removed an unused popup plugin that was loading on every page for a feature nobody was using.
• Fixed faded, low-contrast body text across the site (a leftover theme default that made several pages harder to read than they should have been).

Homepage PageSpeed went from 62 to 76 on desktop and 57 to 70 on mobile. Nothing about how the site looked changed, it just stopped shipping so much dead weight.

The result

Faster pages, and no visible change for patients booking an appointment, which is exactly the point. The best outcome for this kind of maintenance work is that nobody notices anything happened, except that the site loads faster than it did before.

Compass Clinic has stayed on as an ongoing maintenance client since. In their words: "Adel and AGPixels have been helping me for quite sometime with my business website and they have been great. Very skilled and professional." That's the kind of review that comes from fixing the boring, unglamorous problems consistently, not just shipping a nice-looking launch.

Common questions

Do you have to rebuild a site to fix performance problems?
No. Most performance issues on an existing WordPress site can be fixed in place: image sizing, font loading, and unused plugins. A rebuild is only needed when the design itself, not the setup underneath it, is the problem.

What's usually slowing down an older WordPress site?
Oversized images served larger than they're displayed, plugins left installed after they stopped being used or configured, unconsolidated font and script requests, and theme defaults nobody revisited after launch. Individually small, they add up.
