Seo
Audit backlink profiles and score link toxicity so you can clean up SEO risk before rankings or traffic compound.
Overview
seo is an agent skill most often used in Launch (also Grow, Validate) that applies a 30-pattern backlink quality methodology so solo builders can classify toxic links before disavow or outreach decisions.

What problem does it solve?
You have a backlink export full of unknown domains and no consistent way to separate definite spam, questionable guest posts, and links worth keeping.
Who is it for?
Solo builders auditing inbound links after migration, guest-post campaigns, or competitor spikes who want agent-guided triage before touching Search Console disavow files.
Skip if: Teams that only need on-page title-tag rewrites with no link data, or anyone expecting automated fetching of live backlink APIs without supplying exports or tooling themselves.
When should I use this skill?
When you need to audit, score, or triage inbound backlinks for spam, PBN, or penalty risk using a fixed indicator library.
What do I get? / Deliverables
You get tiered toxic-link classifications (auto-flag, manual review, monitor) mapped to the 30 indicators so you can prioritize disavows, outreach cuts, and ongoing monitoring with less guesswork.
- Tiered toxic-link classification aligned to the 30 indicators
- Prioritized manual-review queue for likely spam patterns
- Monitor list for borderline links to recheck on the next crawl

Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Canonical shelf is Launch because backlink quality scoring and toxic-link triage are core off-page SEO work you do when making the site visible and trustworthy in search. Fits the seo subphase as a procedural methodology for evaluating inbound links, PBN patterns, and disavow-worthy spam—not a one-off content tweak.
Where it fits
Classify post-migration backlinks into auto-flag and manual-review buckets before submitting a disavow file.
Score guest-post and partnership links from a content campaign to drop network-style placements early.
Review launch-directory and PR links on a new landing page so you do not inherit toxic patterns before scaling paid traffic.
How it compares
Use as a structured SEO audit checklist in skill form—not as an MCP server that connects directly to Ahrefs or Moz APIs.
Common Questions / FAQ
Who is seo for?
seo is for solo and indie builders using AI coding agents who own a site’s search visibility and need repeatable backlink risk scoring without hiring a full-time SEO analyst.
When should I use seo?
Use seo in Launch when cleaning up off-page SEO before or after a migration; in Grow when reviewing content partnerships and guest posts; and in Validate when checking whether early directory or launch PR links are safe.

Exact-match anchor text from 5+ unrelated domains 5. Links from doorway pages (thin content, keyword-stuffed) 6. Links from hacked sites (pharma/casino injections) 7.
