What's on this site
This site publishes one thing and everything else exists to explain it: the Local Digital Visibility Index, a set of league tables scoring South West businesses on how findable they actually are.
Around that sit four supporting sections. Answers deal with the questions business owners actually ask, using the measurements rather than opinion. The knowledge base is for practitioners who want the technique. The glossary covers the statistical methods used to analyse published results — it explains the analysis and computes no score. The analyses are what the data turned out to say, including the parts that were inconvenient.
This page used to be a hand-written topical map. It went stale within days of being written: it listed twelve destinations and knew about none of the answer pages, the score definition, the cross-index comparison, or four of the analyses. Every figure elsewhere on this site is computed at build time so it cannot drift from what it describes, and there was no good reason for the site’s own map to be the exception. It is now read from the content collection.
1479 pages, of which 1371 are individual business scorecards. Everything below is read from the site itself when this page is built, so it cannot fall behind what it describes.

The indices 39
The league tables themselves, plus how the score is defined and every change ever made to it. 0 sector indices and 1371 individual business scorecards are counted here rather than listed — a scorecard is the same shape 1371 times over, and the index page for each sector is the way in.
