Best match is an order, not a score. This page says what that order is, what you can change it to, and what it does not mean.
Placement first, the score after it.
The default order of a listing is the one labelled Best match. It is the order the directory serves: placement first, the FlymediScore after it. So it is not a ranking by score, and we never label it as one. The sort control gives you the strict orders instead: FlymediScore, number of reviews, or price. The FlymediScore sort weights review volume too, so a top score from a handful of reviews does not outrank a slightly lower one from many; the score we show on the card is unchanged.
The served order of a listing is settled before you touch it. Clinics come in placement order first, then by FlymediScore, then by number of published reviews, and a stable identifier breaks whatever tie is left, so the same listing does not shuffle between visits.
Filters run before any sort, so a sort only reorders the clinics your filters left. You can filter on price band, on a minimum FlymediScore and on accreditation.
Placement is a value we hold against a clinic in our own database. It is a commercial matter rather than something the site works out, the policy behind it is not published yet, and so this page does not state it.
Clinics operated by Flymedi are listed first.
