Read these once. They explain the vocabulary the rest of the docs assume.

- [Sites and GSC sync](/pro/docs/concepts/sites-and-gsc-sync) - how Pro pulls your data, what freshness to expect, multi-site scoping.
- [Analysis presets](/pro/docs/concepts/analysis-presets) - the 8 filters (striking-distance, opportunity, decay, etc.) and when to use each.
- [Indexing verdicts](/pro/docs/concepts/indexing) - what each Google status means in plain English.
- [Core Web Vitals](/pro/docs/concepts/core-web-vitals) - LCP, INP, CLS thresholds and what moves them.
- [License and gating](/pro/docs/concepts/license) - what works without a license, what doesn't.
