Site Health score
The site health score is a single number, out of 100, summarising how well your site is set up - and a ranked list of what to fix.
The grades
| Score | Grade |
|---|---|
| 90 and above | Excellent |
| 75 to 89 | Good |
| 50 to 74 | Fair |
| Below 50 | Poor |
What is measured
Five dimensions, and they do not count equally. SEO and Setup carry the most weight, then Page speed, then Accessibility, then Links.
| Dimension | What it checks |
|---|---|
| SEO | Whether pages are published, and whether they have SEO titles and meta descriptions. |
| Setup | The launch essentials: a homepage, more than one page, a custom domain, a store that can actually take money, demo products and placeholder testimonials replaced with real ones. |
| Page speed | Real loading performance from real visitors - Core Web Vitals over the last 28 days. |
| Accessibility | Whether images have alt text, so screen readers and search engines can describe them. |
| Links | Whether internal links point at pages that exist. |
A missing dimension is not a zero
A dimension with nothing to measure yet - typically page speed on a brand-new site with no visitors - drops out, and the others are re-weighted. It does not drag your score down. Once you have traffic it starts counting.
The fixes list
Up to six fixes, most important first, each linking to the place that fixes it. Work top-down: the ordering already reflects how much each one is costing you.
Some are one-off and permanent - connect a domain, add a homepage, replace the demo products. Get those out of the way and the score moves a long way in one sitting.
What it is and is not
It is a checklist of things that are objectively worth doing. It is not a ranking prediction, and 100 does not mean Google will love you. A site scoring 85 with a genuinely useful page beats a site scoring 100 with nothing to say.
Treat it as the pre-flight check: get it into the green, then go and do the work that actually brings people in.
