# Module 3 — Reading the link graph

_A tier 1 link means nothing until you know what links to it. Six lessons on reading a profile at depth._

## Checklist

- [ ] Record Fresh and Historic link and referring-domain counts separately, and never quote one as if it were the other
- [ ] Compute the Fresh-to-Historic referring-domain ratio before drawing any conclusion about decay
- [ ] Report referring domains, not links; note the distinct-versus-duplicate split if you must report links
- [ ] Run the Link Graph at all tiers and record domains, links and links per domain
- [ ] Repeat at tier 1, tier 2, tier 3 and tier 4 and put the four readings in one table
- [ ] Flag any tier where links per domain is exactly 1.0, or above roughly 3
- [ ] Scan each tier for runs of domains with near-identical Trust Flow and Citation Flow
- [ ] Check whether Citation Flow sits consistently above Trust Flow by a similar margin across a cluster
- [ ] Sort Topical Trust Flow by TTF value, never by referring domains
- [ ] Read Flow Metric History for a decade of context before treating any single reading as a change
- [ ] Compare the backlink-history curve against the referring-domain curve to catch one-domain spikes
- [ ] Resolve the domain's IP addresses, check every one, and discount the result entirely if it is behind a CDN
- [ ] Compute referring domains per Class C subnet rather than trusting a neighborhood list
- [ ] Read Related Sites with a human filter for string-similarity false positives
- [ ] Run Clique Hunter against a known-unrelated site to calibrate what a null result looks like
- [ ] Separate findings you control (your tier 1) from findings you do not (everything from tier 2 outward)
- [ ] Write the disavow recommendation last, and default to recommending nothing
