# Backlink Profile — quire.io (/guide/ focus)

**Data tier: 0 (Common Crawl + verification crawler only).** No Moz or Bing
Webmaster API keys are configured in this environment
(`python3 scripts/backlinks_auth.py --check --json` confirms both services
unavailable — no `MOZ_API_KEY`, no `BING_WEBMASTER_API_KEY`, and no
`~/.config/claude-seo/backlinks-api.json`). This is an **environment setup
gap, not a finding about quire.io's link profile** — treat it as a
recommendation, not a site defect.

## What data is available at Tier 0

| Source | Confidence | Freshness | Grain |
|---|---|---|---|
| Common Crawl Web Graph | 0.50 | Quarterly (current release: cc-main-2026-jan-feb-mar) | **Domain-level only** |
| Backlink verification crawler | 0.95 (per-link, when a candidate list is supplied) | Real-time | Page-level |

No known-backlink list was supplied for this audit, so the verification
crawler (`scripts/verify_backlinks.py`) was not run — there was nothing to
verify against. It remains available for spot-checking specific referring
URLs (e.g., partner directories, community forum threads) if a candidate
list is provided later.

## Common Crawl Domain Metrics — quire.io

Source: Common Crawl Web Graph (confidence: 0.50, domain-level, quarterly)

| Metric | Value | Notes |
|---|---|---|
| In crawl | Yes | Domain is indexed in Common Crawl |
| In rankings | Yes | Domain has a computed graph rank |
| PageRank (raw) | 1.44e-07 | Not human-interpretable in isolation |
| PageRank rank | 199,758 | Out of all domains in the CC graph (lower = better authority) |
| Harmonic centrality | 17,605,452 | Raw score |
| Harmonic centrality rank | 43,339 | Out of all domains in the CC graph (lower = better reachability) |
| Hosts under domain | 2 | e.g., quire.io + www.quire.io — not a link-authority signal |
| Top referring domains | none returned | CC's domain graph did not surface a referring-domain sample for quire.io in this release |
| Referring domains sample size | 0 | — |

**Interpretation:** A harmonic-centrality rank in the ~43K range (out of
billions of domains in the CC graph) suggests quire.io sits in a
reasonably well-connected tier for a mid-size B2B SaaS site — better than a
brand-new or orphaned domain, but this is a coarse directional signal, not
a DA-equivalent score. PageRank rank (~200K) is consistent with a
moderate, not dominant, authority profile. **Do not read a specific numeric
rank as equivalent to a Moz DA or Ahrefs DR score** — they are computed on
different graphs with different scales.

**Critical limitation:** Common Crawl's web graph is computed at
**host/domain granularity**, not URL-path granularity. It cannot tell us
whether inbound links point to `quire.io/guide/*` specifically versus the
marketing site, app, or blog. There is no free/no-key source available in
this environment that reports path-level (subdirectory) backlink data.
Getting a `/guide/` specific referring-domain count, anchor text profile,
or toxic-link ratio requires Moz, Bing Webmaster (for the domain's own
verified property), or DataForSEO.

## Scoring — factors covered vs. skipped

Per the confidence-weighted scoring model, only 1 of 7 weighted factors has
any data source available at Tier 0 (referring domain count, via CC's
in-degree proxy — and even that returned an empty referring-domain sample
for this domain/release). The other six factors (domain quality
distribution, anchor text naturalness, toxic link ratio, link velocity,
follow/nofollow ratio, geographic relevance) have **zero data sources** at
this tier.

**Per the Tier 0 policy: this is reported as INSUFFICIENT DATA, not a
numeric Backlink Health Score.** Producing a 0–100 score from a single
partial, domain-level, no-referring-domains-returned signal would
misrepresent the actual link profile (positively or negatively) and is
avoided here by design.

## What works (available signal only)

- quire.io is indexed and ranked in the Common Crawl web graph (not an
  orphaned or newly-registered domain from the graph's perspective).
- Harmonic centrality rank (~43K) is in a respectable band for a company
  site of this size, suggesting the domain is reachable from a reasonable
  number of other crawled pages.

## Recommendations

1. **Set up Moz API access** (free tier, 2,500 rows/month) to unlock DA/PA,
   referring-domain counts, anchor text distribution, and spam score for
   quire.io and the `/guide/` subdirectory specifically. This is the
   single highest-value unlock for future backlink audits of this site.
2. **Verify quire.io in Bing Webmaster Tools** (free) to get inbound-link
   data and competitor link-gap comparisons.
3. **If budget allows, enable the DataForSEO extension**
   (`./extensions/dataforseo/install.sh`) for the highest-fidelity,
   path-level backlink data, link velocity trends, and follow/nofollow
   ratios — none of which are obtainable from free sources.
4. Once any of the above is available, re-run this audit focused
   specifically on `quire.io/guide/*` URLs (not just the root domain) to
   see whether help-center pages earn their own inbound links (e.g., from
   community forums, Reddit threads, YouTube tutorial descriptions, or
   partner integration docs) versus relying entirely on domain-level
   authority inherited from the marketing site.
5. In the meantime, if you have a list of known backlinks (e.g., from
   Google Search Console's Links report, which is free and already
   available if Search Console is set up), supply it and the verification
   crawler can confirm live status, anchor text, and follow/nofollow
   attributes for each one at page level (confidence 0.95 per verified
   link).
