domain-authority

domain-authority is a skill for Claude Code from prashishh/seo-geo-report-engine. It costs 137 tokens per session (688 once invoked), scanned A, original, MIT.

A tool for comparing a website’s authority score across several SEO data providers, including scores for its competitors. It converts the different measures to a common 0–100 scale and reports an average plus disagreement between sources.

In plain words
What is it for?
Use it to rank a client and its competitors by domain authority, review referring domains and backlinks, and save the comparison as project data.
Why use it?
A single authority score can be misleading because each provider calculates it differently. Comparing sources shows whether the result is consistent or uncertain.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

domain-authority scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

domain-authority

Authority ("how much trust a domain has earned") is a proxy, and every provider computes it differently, so one number is fragile. This reads it from EVERY source available and reports the consensus + spread.

python3 tools/seo/authority.py --project <slug>                 # client + client.yml competitors
python3 tools/seo/authority.py --domains a.com b.com c.com      # ad-hoc set
python3 tools/seo/authority.py --project <slug> --out projects/<slug>/data/raw/dataforseo/authority-<date>.json

Sources (each optional and graceful, missing keys are skipped)

  • DataForSEO - always on (we own it): rank 0-1000 + referring domains + backlinks, one bulk call.
  • Ahrefs - Domain Rating 0-100 (the recognized number), one call per domain, if AHREFS_API_KEY set.
  • Open PageRank (DomCop) - FREE 0-10 link score, 100 domains/call, if OPENPAGERANK_API_KEY set (free key from domcop.com/openpagerank). The best "bulk authority at $0" source.
  • Moz - Domain Authority 0-100 (the other recognized number), if MOZ_TOKEN set.

Output: a ranked table of client + competitors with each source's normalized score, the consensus (mean of available sources), and the spread (max-min). Big spread = the sources disagree, investigate before quoting. Writes data/authority.csv. If an API source is unavailable and you only need a recognized number for a few domains, grab Moz DA / Semrush Authority Score free by hand (see knowledge/seo-geo-tooling-landscape.md).

Notes

  • Powers the first-scan-report authority section and the competitor-analysis / kpi-dashboard authority pillar. Cross-check the headline number against Ahrefs before quoting a client (Ahrefs DR is the client-recognized metric; DataForSEO/Open PageRank are the cheap bulk cross-checks).
  • The recipe stays internal; show the client the consensus number, not the method.
  • To add sources: Open PageRank + Moz keys light up two more columns instantly (config/secrets.env).
