Most SEO consultants use Claude like a smarter search engine. A few use it like a trained team member. The difference is SKILL.md.

You run Screaming Frog, export the CSVs, pull GSC separately. Then the analysis begins — scrolling, flagging, cross-referencing, tab by tab. At some point you paste a chunk into ChatGPT and ask what the issues are. You get an answer based on that chunk alone. You paste another section, get another answer. But ChatGPT only ever sees what you just pasted. It has no idea what the GSC data says, what the business does, or what came out of the previous paste. The findings never connect. You are the one holding all the context together, which means you are still doing the hard work manually.

By the time the report is done, eight hours have passed for work that should have taken three. Content is the same story, hours of research before a single word gets written, a brief that comes back generic, half of it rewritten before it goes anywhere.

For a brain that does not do well with long stretches of repetitive manual work, this is the most draining part of the job.

I went looking for a fix the usual way: YouTube videos, LinkedIn posts, GitHub repos. The concept existed. The hard part was building something that matched how I actually work. SKILL.md is what I landed on.

What Is a SKILL.md File?

A SKILL.md file is a plain text instruction set that teaches Claude how to handle a specific type of task, consistently, every time it is triggered. It encodes your methodology, your output format, your editorial standards, and your judgment logic into a document Claude reads before beginning any work in that category.

When Claude reads it at the start of a session, it internalizes the instructions and applies them throughout. Your preferred audit structure becomes Claude’s default audit structure. Your report format becomes what Claude produces without being asked. Your threshold for what counts as a critical issue becomes the threshold Claude applies.

The file is not a prompt. You do not paste it into the chat box before each session. It lives in a Claude Project as a persistent instruction set, and every conversation inside that project inherits it automatically.

For SEO consultants, this matters because the work is structurally repeatable even when the specifics vary wildly between clients. Every audit follows a framework. Every content brief has the same essential components. Every monthly report covers the same categories. The expertise is in the judgment calls made at each step, and a well-built SKILL.md captures those calls and makes them the default.

How SKILL.md Works in Practice

The file lives in a directory Claude can access at runtime, or in your Claude Project instructions. When Claude reads it, the instructions shape how it approaches the entire session.

A well-structured SEO SKILL.md defines four things.

Trigger conditions. The inputs or requests that activate the skill. An audit skill triggers when someone uploads a Screaming Frog export, pastes a domain, or asks to review technical SEO. Claude recognizes these signals and routes accordingly.

1. Trigger conditions: The inputs or requests that activate the skill (e.g., Screaming Frog exports or GSC data).
2. The methodology: Your step-by-step framework, including specific checks, thresholds, and decision rules.
3. The output format: The structure of the deliverable, whether client-facing reports or internal notes.
4. Tone and formatting rules: Editorial standards like “no em dashes” or “tables for lists of four or more items.”

What a Real SEO Audit Skill Looks Like

My audit workflow starts with Screaming Frog. I run the crawl, export everything — response codes, page titles, H1s, inlinks — then pull the GSC performance and coverage reports separately. Before the skill existed, the analysis happened in fragments. Data in one tab, findings in another, report assembling in a third. By the time everything was synthesized into something client-ready, the day was mostly gone.

Now I feed both exports into Claude together in the same session. The skill combines them, cross-referencing crawl findings against search performance, flagging technical issues that are actually costing rankings, and structuring everything into the nine-section report format I use across every engagement. The output needs a final read, not a rebuild.

The skill begins with a description block listing every input type it accepts: Screaming Frog exports, Google Search Console data, GA4 reports, PDF audits from Ahrefs or SEMrush, raw domains. Claude reads this and knows what it is working with before the first section begins.

Then it walks through each audit section in sequence. Section 1 establishes business context before any data is touched — what the business does, who it serves, what conversion looks like, who the organic competitors are. This shapes how Claude weighs every finding that follows.

Section 4, technical SEO, is where the skill earns its value most visibly. Rather than letting Claude decide what counts as important, the skill defines it. DOM size over 1,500 nodes is a priority issue. Redirect chains get flagged regardless of whether the client mentioned them. 302s used in place of 301s appear in every audit by default. These are not things Claude has to be reminded of. They are built into the methodology.

Section 7 covers AI and LLM visibility: llms.txt presence, structured data quality for AI parsing, entity clarity, answer-optimized content, citation potential. This section exists because ranking in 2025 includes being referenced by AI systems, and the skill encodes that reality into every audit automatically.

Section 9 produces the prioritized action plan in three tiers: critical fixes within 30 days, high-impact improvements within 60 to 90 days, and ongoing workflow items. Every recommendation includes what the issue is, why it matters, how to fix it specifically, and a priority score. The skill requires this structure so Claude delivers it every time.

Beyond Audits: Other SEO Skills Worth Building

The audit skill is the highest-leverage starting point because audits are the most time-intensive deliverable. The same logic applies across the full workflow.

The content brief skill is the one I use most for CrunchWiser. I write everything myself, which means the brief is not a handoff document, it is my own research organized before I start writing. Before the skill, that research phase consumed hours. Topic analysis, competitor article review, semantic keyword mapping, internal linking decisions,  all assembled piece by piece before a word of the actual article was written. The skill compresses that into one session. I give it a keyword, it returns a full brief in my structure: intent classification, full heading outline, semantic terms to cover, E-E-A-T requirements, internal linking targets, and a differentiation angle. The research still happens, but the time between keyword and ready-to-write dropped significantly.

An on-page optimization skill takes a crawl export and returns a prioritized list of title tag rewrites, meta description improvements, and heading structure fixes formatted as a spreadsheet-ready table. The skill defines your length thresholds, keyword placement logic, and what qualifies as a duplicate, so Claude applies your standards rather than general best practices.

A monthly reporting skill takes raw GSC and GA4 data and drafts the client report in your format, in your voice, at the level of plain-English clarity your clients actually need. Traffic movement, keyword position changes, technical issues resolved, wins, next month priorities,  structured the same way every month without starting from a blank template.

A backlink qualification skill defines what a good prospect looks like for your client type: DR range, topical relevance criteria, spam signals to filter out. Claude screens a prospect list against this logic faster than any manual review.

How to Write Your First SKILL.md

Start with the deliverable that takes the most time and follows the most consistent structure. For most SEO consultants that is the technical audit or the monthly client report.

Open a plain text file. Write in clear, directive language. Treat it as a briefing document for a capable new collaborator who is sharp but completely unfamiliar with your preferences and standards.

Cover these elements in order.

Name and description. A one-sentence description of what the skill does and what triggers it. This matters when multiple skills are loaded into the same project.

Accepted inputs. Specific data types the skill is designed to work with. “Screaming Frog all_inlinks CSV” is more useful than “SEO data.”

The methodology. This is the core of the file. Walk through your process step by step. Include the thresholds that matter to you. Include the judgment calls you make consistently. Getting this right took me a few real sessions to iterate through, the first version was too general, and testing it on actual client work revealed exactly which sections needed more specificity.

Output format. Describe the deliverable structure in concrete terms. If it is a DOCX report, describe the section order. If it is a spreadsheet, describe the columns.

Tone and formatting rules. The editorial standards Claude applies to every output this skill produces.

Save the file as SKILL.md. In Claude Projects, paste the contents into the project instructions. Create one project per skill type and every conversation inside it inherits the methodology automatically.

5 Copy-Paste Ready SKILL.md Templates

The 5 templates below cover the most common repeatable deliverables in an SEO consulting workflow: the full audit, the content brief, and the monthly client report. Each is ready to use as written or to adapt with your own thresholds and standards.

The Compounding Value

The result that surprised me most was not speed. It was consistent.

Once the skill was stable, Claude started producing output that matched the structure, the brand standards, the tone, the formatting rules, session after session without variation. That does not happen with individual prompts, because prompts vary with how you write them on a given day. The skill does not vary. It carries the same methodology into every session regardless of how the work started or how much time passed between engagements.

For consultants managing multiple clients, this compounds quickly. Audits follow the same nine-section framework at the same depth across every engagement. Monthly reports draft from raw data in the same structure, in the same voice, ready for a final read before they go out. The deliverable quality stops depending on how well you prompted that day.

The investment is one documentation session per deliverable type. Write the skill, test it on two or three real engagements, refine the sections where Claude diverged from your intent, and the methodology is encoded permanently. Every project that follows runs on it.

That is the practical case for SKILL.md. Your process, written down once, running correctly every time.
