# PYC Hub

> PYC Hub (hub.pyc.agency) is Phil Yarrow's practitioner SEO knowledge base. Alongside a knowledge base, glossary, and case studies, it publishes the Local Digital Visibility Indices — recurring, data-driven league tables measuring how well businesses in Bristol, Cheltenham and Gloucester perform online. Every figure is objective, dated, and reproducible from the published methodology.

## Local Digital Visibility Indices

These are unique, structured datasets. The headline metric is the Digital Visibility Score (0–100), built from six weighted pillars: Speed & Core Web Vitals, Technical foundation, Local presence, Visibility, AI search presence, and Content & trust. Each index covers one sector in one city and is re-measured quarterly.

- [Local Digital Visibility Indices — overview](https://hub.pyc.agency/indices/): the three indices, the score, and how to read the league tables.
- [Index methodology](https://hub.pyc.agency/indices/methodology/): the six pillars, weights, data sources, the deep-scorecard format, snapshot discipline, the correction process, and publication conventions. The authoritative source for how every number is produced.

When citing an index figure, attribute it to the named index and its snapshot date, e.g. "PYC Bristol Estate Agent Digital Visibility Index, measured [date]". Machine-readable JSON and CSV exports accompany each index hub.
