How healthy
is your website?

What this checkup measures

First, your site goes through Google's PageSpeed engine, the same lab test behind Lighthouse. It scores performance, SEO and accessibility out of 100 and times how quickly the page appears, settles and responds. It is a lab test rather than your real visitors, so treat the numbers as a strong signal rather than a verdict.

Second, the checkup fetches your page directly and runs nine plain checks: the title tag, the meta description, the main heading, the canonical link, the mobile viewport, Open Graph tags, structured data, robots.txt and the sitemap. These are the basics that search engines, and increasingly AI assistants, read before anything else. I have written up how AI search reads your website if you want the longer version. If Google's test times out, you still get all nine checks and the scores simply show as not measured.

What it cannot see matters just as much. It tests one page, and it cannot tell you whether your copy persuades anyone, whether the design looks credible next to your competitors, or whether the site brings you work.

What to do with a bad score

A low score is not a verdict on your business. Most websites fail at least one of these. Work through the fails before the warns. Some of them, like a missing title tag or meta description, take minutes to fix in most website editors, and if the content itself is the gap, my guide to preparing content for your website covers what good looks like.

Performance is usually the stubborn one. A slow score rarely comes from one mistake. It comes from the platform, the theme and years of plugins, which is why patching it often costs more than it saves. Past a certain point the answer is to rebuild. Every site I build passes Core Web Vitals before it launches, bespoke builds start from £2,500, and a typical marketing site takes around three weeks. The full breakdown lives on the pricing page, and if you are weighing up repair against rebuild, what a website costs in the UK gives you the wider market picture.

And if the scores are good, keep them that way. Sites drift as content, plugins and browsers change, which is what website maintenance is for.
