Writing for the Goldilocks Zone: AI Readiness

I recently went down a bit of a rabbit hole researching how large language models actually select content to cite. I wanted to understand the practical mechanics. When an AI system surfaces a passage from a webpage, what made that passage the one it chose? And more importantly, what does that mean for how we […]

AI Won’t Replace Your Website. But It Will Ignore a Bad One.

There’s a Google patent doing the rounds that’s making website owners nervous. The idea: Google generates its own AI-powered landing page for your business, right inside the search results. No click required. No visit to your site. The obvious question is a reasonable one. If Google can synthesise your content into their own page, why […]

The Platform Illusion: Why Managed Hosting Isn’t the Same as a Managed Site

There’s an appealing pitch that comes with hosted platforms like Shopify, Squarespace, and Webflow. The servers are managed. The uptime is “99.9%.” Security patches happen automatically. The message, implicit or otherwise, is that the hard stuff is taken care of. It’s a tempting thought – but it’s only half the story. The platform handling your […]

Securing Cookies in 2026: Dealing with CHIPS and the End of Third-Party State

Following on from the header updates, I’ve also had to refactor the Cookie Scanner. With the final nail in the coffin for unpartitioned third-party cookies in 2026, the way we audit cookies had to change. If you’re running embedded widgets—like support chats, maps, or auth providers—that rely on cross-site state, the old way of doing […]

Analysing Web Performance: A Look at the Wix Showcase Sites

This is the first in a series of articles I plan to write, based on our research at Sitevitals into platform-specific site health. In this first article i want to look at Wix websites and how they stack up, performance wise. Rather than pick any old random Wix websites, we audited of the 85 websites […]

Turn Your Client Portfolio Into a Continuous Opportunity Engine

We know the reality most agencies face: websites don’t usually break all at once; they quietly drift over time. An SSL certificate expires unnoticed. A script update slows down the Largest Contentful Paint. A critical tracking tag is accidentally deleted. A security header is dropped during a routine deployment. Individually, these issues are small. Collectively, […]

Securing the Web in 2026: Why I’ve Upgraded the SiteVitals Header Scanner

I recently spent some time digging into the latest security standards for 2026, and as usual, things have moved on quite a bit from what was considered “best practice” just a couple of years ago. It turns out that simply having a CSP or HSTS header isn’t quite enough anymore if you want to stay […]

Server-Side GTM + Meta CAPI: Why Your Events Fire but Don’t Optimise

One of the more frustrating moments in our server-side GTM + Meta Conversions API implementation came after everything appeared to be working. The setup seemed perfect: Events were firing and requests returned 200 OK. Deduplication was functioning correctly. User data was present and match quality had improved. And yet… Meta still refused to optimize. No […]

Server-Side GTM + Meta CAPI: User Data, Match Quality, and the Hidden Transformation Layer

Following on from our earlier WooCommerce walkthrough If you’ve implemented server-side Google Tag Manager with Meta’s Conversions API and everything appears to be “working” — events firing, HTTP 200 responses from Meta, no obvious errors — but Event Match Quality is poor, you’ve likely hit the same wall we did. This post documents the missing […]

Implementing Server-Side Google Tag Manager with Meta Conversions API

A practical, code-driven walkthrough using WooCommerce Client-side tracking is becoming less reliable every year. Ad blockers, browser privacy features, and tightening cookie rules all reduce the accuracy of traditional pixels. Server-side tracking using Google Tag Manager (sGTM) and Meta’s Conversions API (CAPI) is currently the most robust way to track high-value events like purchases – […]

AI Image Editing with Gemini: The Reality, The Wall, and the Power of the Hypothetical

A true story of a project we undertook right here on this website, and how we overcame frustrating AI limitations.

ChatGPT Vs Gemini: Which coding assistant is better? [2025 update]

Back in May 2023 (have we really had AI in our lives for that long!) I wrote an article comparing ChatGPT and Bard (now rebranded as Gemini) as coding assistants. Now, a couple of years later, I decided to revisit the free AI offerings from OpenAI and Google to see how they measure up. The […]
