Where Cardiff dental websites fall short
“Not detected” means a signal was absent from the homepage and up to two linked pages in a bounded crawl; it does not prove the signal is absent everywhere on the site. Every percentage shows its own evaluated base; checks evaluated on fewer than 30 Cardiff websites are omitted.

2026 UK study baseline
The frozen national picture for the same checks
Rates from the 8,627-website 2026 UK study cohort — a frozen study base that counts every audited domain, so it is a different denominator than the live evaluated figures above and the two must not be read as one series.

Methodology and limitations
How these live figures are computed
Live cohort. Figures cover the indexable audited practice websites currently published for Cardiff in the DentalPresence index and recompute as sites are re-audited, so they will drift from the frozen 2026 study numbers over time. Each check's percentage uses only the websites where that check was actually evaluated, shown as its base.
Scoring. Methodology dps-37-v1: a bounded HTTP crawl of robots.txt, sitemap signals, the homepage, and up to two linked internal pages, scored across 37 deterministic checks. “Not detected” is a limited observation, not proof of absence.
What is excluded. Crawl-accessibility findings (DNS failures, blocked crawls, timeouts) come from the frozen study run and use a different cohort base, so they are not restated here — see the Wales benchmark for them. Percentages are withheld wherever fewer than 30 websites form the base.
No clinical claims. Website signals only — not a clinical rating. These figures do not use rankings, traffic, conversions, credentials, or patient outcomes, and a failed check is not proof of lost revenue or poor care.
