THE SHORT ANSWER
10 Claude Code skills every SEO should build
The most useful Claude Code skills for SEO encode repeatable, evidence-led workflows: crawl diagnosis, indexation checks, redirect validation, metadata QA, schema validation, internal-link mapping, content-brief production, content-decay review, analytics reporting, and release QA. In Claude Code, a skill is a reusable set of instructions and supporting resources, not magic SEO software. Build each skill around approved data sources, explicit outputs, and validation steps.

Check current features and pricing on the official site- A Claude Code skill packages reusable instructions, reference material, and optionally scripts for a recurring job.
- Start with workflows you already perform consistently; do not automate an undefined SEO process.
- Crawler, Search Console, analytics, and rank data need approved exports or narrowly scoped connections.
- Generated recommendations require source checks and human prioritisation before publication or deployment.
What a Claude Code skill is
Anthropic describes skills as reusable knowledge or invocable workflows stored as instructions, with full content loaded when the skill is used. For SEO, a good skill might define required exports, checks, output columns, severity rules, and the script used to validate results. Keep universal repository rules in CLAUDE.md; keep specialist procedures in skills so they load only when relevant. Sources: Claude Code skills and extensions, Agent Skills documentation
1. Technical crawl triage
Accept a crawler export, group issues by template and root cause, distinguish symptoms from blockers, and produce a prioritised table with example URLs. The skill should never infer sitewide impact from one row. Require counts, affected templates, evidence, proposed owner, and a verification step after the fix.
2. Indexation reconciliation
Compare the canonical URL inventory with approved Search Console exports, sitemap URLs, robots directives, status codes, and canonical tags. Flag contradictions such as an indexable sitemap URL that redirects or declares another canonical. The output should separate observed facts from hypotheses; only Google can determine final indexing.
3. Redirect and migration QA
Validate old-to-new URL mappings for one-hop destinations, loops, chains, status codes, protocol and hostname consistency, query rules, and high-value unmapped pages. Require a dry-run report and sample checks before changing configuration. After launch, rerun against production and preserve the mapping as an audit artifact.
4. Metadata and SERP QA
Check titles, descriptions, headings, canonicals, robots directives, social metadata, duplication, truncation risk, and templating errors. A useful skill proposes changes from the page’s actual purpose and source content; it does not stuff a keyword into every field. Require a human to approve claims and brand language.
5. Structured-data generation and validation
Map eligible page content to the appropriate schema vocabulary, generate JSON-LD, and test that every property is supported by visible page content. Include syntax validation and eligibility checks against current search-engine documentation. Never invent reviews, ratings, prices, authors, or FAQs just to fill a schema type.
6. Internal-link opportunity mapping
Combine a URL inventory, page topics, existing links, and commercial priorities. Suggest contextually relevant source-to-target links with proposed anchor wording and the paragraph where each belongs. Enforce diversity naturally, avoid orphaning useful pages, and reject links that exist only to manipulate anchor text.
7. Evidence-led content briefs
Turn a confirmed query set, audience problem, first-party expertise, competitor gap notes, and product facts into a brief with search intent, questions to answer, unique evidence, outline, and verification requirements. The skill should identify missing research instead of filling gaps with plausible prose. It should also define what the page will do better than existing results.
8. Content decay and refresh queue
Compare time periods from approved analytics and Search Console exports, then surface pages with meaningful declines, stale facts, broken links, weakened conversion paths, or changed intent. Control for seasonality and site changes where possible. Output a queue with evidence and recommended action: refresh, consolidate, redirect, preserve, or investigate.
9. SEO reporting with decisions
Transform stable exports into a concise report that separates leading indicators, outcomes, anomalies, and decisions needed. Include definitions, date ranges, comparison logic, and links to source files. Do not let the agent turn correlation into causation. A useful report ends with owners and next actions, not a collage of charts.
10. Pre-release SEO QA
Inspect changed routes and templates for status codes, canonicals, metadata, headings, structured data, navigation, internal links, sitemap inclusion, robots behaviour, image alternatives, and performance regressions. Use scripts or hooks for deterministic checks and the skill for interpretation. Block the release only on documented criteria, and record exceptions.
How to build the first one
Choose the SEO procedure you have repeated at least three times. Write its inputs, ordered checks, output format, failure states, and validation command. Add one realistic fixture and test the skill on a small set before a whole site. Version it with the project and improve it when reviewers correct the same mistake twice.
