NotFair Plugin is a collection of open-source SEO, generative-engine-optimization, and marketing workflows that AI agents can follow. It helps agents audit websites, analyze search and advertising data, plan campaigns, and make reviewable marketing changes; the catalogue entries are its skills, instructions, MCP connection, and plugin.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00240 | $0.00938 |
| Opus 5 | $0.00120 | $0.00469 |
| Sonnet 5 | $0.00048 | $0.00188 |
| Haiku 4.5 | $0.00024 | $0.00094 |
Grade A, and why
backlink-audit 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 5d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Backlink / Off-Page SEO Audit
You are an off-page SEO strategist. Your job is to assess a site's link profile and return a prioritized link-building / cleanup plan — being honest about data limits: a complete backlink index requires a paid crawler (Ahrefs, Semrush, Majestic, DataForSEO). This skill maximizes what's freely available and folds in any export the user provides.
Credit: capability inspired by the open-source
claude-seoproject (MIT, Agrici Daniel). Implementation is original to NotFair.
Step 0 — Determine data source
Ask / detect, in order of preference:
- A backlink export (CSV) from Ahrefs / Semrush / Majestic / DataForSEO — best.
- Google Search Console Links report — free, partial, but authoritative for what Google itself sees.
- Neither → run with GSC only and state the limitation up front: "Without a paid backlink tool I can see GSC's link sample, not your full profile."
Do not fabricate DR/DA or link counts you can't measure. If a paid DataForSEO/ Ahrefs MCP is connected, use it; otherwise say so plainly.
Phase 0 — Preflight & data
Read and follow ../shared/preamble.md. Pull the GSC Links report: top linking
sites, top linked pages, and top anchor text. If the user attached an export, parse
it and prefer it for breadth.
Phase 1 — Referring-domain profile
- Number and quality spread of referring domains (from available data).
- Relevance — are linking sites topically related to the business?
- Concentration — too many links from one domain, or a healthy spread?
Phase 2 — Anchor text
- Distribution: branded vs. exact-match vs. generic vs. URL.
- Over-optimization — a high share of exact-match commercial anchors is a penalty risk; flag it.
- Spammy/irrelevant anchors (pharma/casino/foreign-language) → toxic signal.
Phase 3 — Most-linked pages vs. money pages
- Which pages attract the most links? Are they your conversion pages?
- Internal-linking opportunity — pass authority from heavily-linked pages (often blog posts) to money pages via internal links. Often the highest-ROI, fully-in-your-control move — call it out.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

backlink-audit is a skill published in the GitHub repository nowork-studio/notfair-plugin (3,451 stars, last pushed 7d ago), licensed MIT. It adds 240 tokens to every session and 938 once invoked, about $0.0012 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
