SEO Website Audit

The SEO Website Audit is a Claude skill that tears down your site and tells you exactly what's killing your organic traffic. Crawl, diagnose, prioritize. In one prompt.

The Problem

You know your SEO is probably broken. You can feel it. Traffic's flat. Your pricing page isn't ranking for your own brand name. A page you spent a weekend writing is nowhere in Google. Something's off. You just don't know what.

So you do what everyone does. You run a Lighthouse scan and get a screen of yellow and red squiggles. You sign up for a free Ahrefs audit and it spits out 412 "issues," half of them missing meta descriptions on your privacy policy. You consider hiring an agency. They quote you $2,400 and a 67-page PDF in six weeks. You ask a friend who "does SEO." They tell you to "post on LinkedIn more." You close all the tabs.

Three weeks later you're back where you started. Traffic still flat. No idea what to fix first. Nothing shipped.

This skill ends that loop. One prompt, one prioritized report, five fixes you can ship this week.

What this Claude skill does

Crawls your site like a search engine would: homepage, robots.txt, sitemap.xml, plus 3–5 representative content pages pulled from your nav and sitemap.
Checks the 5 things that actually move rankings: crawlability and indexation, Core Web Vitals, on-page (titles, meta, headings, content), E-E-A-T and content quality, and site-type-specific issues (SaaS, local, e-com, content).
Spots the silent killers most audits miss: soft 404s returning 200, broken og:url template bugs, schema markup claiming reviews you don't actually show, indexation gaps between sitemap and site: results.
Ranks every finding by impact: Critical → High → Quick Wins → Long-Term. The blocking-indexation issue goes above the alt-text complaint, where it belongs.
Gives you the exact fix, not "improve your title tag": every issue includes the URL, the broken value, the new value to ship, and a Low/Medium/High effort tag.
Tells you the real lever: if you're a local business, the map pack matters more than position 1. If you're B2B, LinkedIn might drive more leads than blog traffic. The report names the channel that actually matters for your business, not just "more SEO."

Why it's amazing!

Five clear fixes beats fifty vague ones.
You ship the high-impact stuff this week, not after a six-week engagement.
No login, no API key, no $99/mo SaaS to sign up for.
Every issue comes with evidence — a real URL, a real quote, a real number. Nothing made up.

Who it's for

Anyone who has a website and a search bar. But indie hackers, SaaS founders, local business owners, e-com operators, agency owners auditing a new client, and bootstrappers who can't afford a $2,400 audit but can't keep flying blind either. Anyone who's ever closed a Lighthouse report with 200 red squiggles and no idea where to start.

How it works

Ask Claude something like:

"Audit shadcndraw.com."
"Run an SEO audit on my site, https://acme.io — I think Google can't find half my pages."
"Why am I not ranking for my own brand name? Site is mybrand.com."
"Do a technical SEO audit on getloop.app. We just migrated from WordPress to Next.js last month — I want to know if I broke anything."
"Audit https://shopname.com — it's a Shopify store and conversions dropped 30% after the redesign. Focus on what's hurting search and CRO."
"Check https://example.com for soft 404s, missing canonicals, and indexation issues. I don't need the long-term roadmap, just the things that are bleeding."

You'll get back a single markdown file with this shape:

TL;DR — Overall health: Needs Work

Top 5 issues killing performance:

/pricing is a soft 404. Google will silently drop it.

og:url is broken site-wide (template bug — concatenates the domain to itself).

Only 1 of 8 sitemap URLs is indexed in Google.

Visible typos in your H1 and two H2s.

Homepage <title> is just your brand name — no keywords, no hook.

Quick wins (fix today): Fix the homepage title. Fix the og:url template bug. Fix six visible typos. Add <title> and meta descriptions to /blog and /pricing. Remove the soft 404 from sitemap and 301-redirect it.

Then it breaks down each issue with the URL, the evidence, the exact fix, and the effort. Critical Issues → High-Impact → Quick Wins → Long-Term. Plus a "What I Couldn't Check" section that's honest about the limits of a public crawl (no Search Console, no backlinks, no real-user Core Web Vitals).

Closes with a 3-tier Action Plan: this week, this month, this quarter. The founder reads this section if they read nothing else.

Pairs well with these other skills

This audit tells you what's broken — these skills come next once the foundation is solid:

Keyword Research Skill: Fix the foundation first, then find the keywords to fill the content gaps the audit surfaces.
Competitor Teardown Skill: Study the rivals outranking you to see how they position and where you can attack.
Content Ideas Generator Skill: Turn the content gaps into a concrete publishing plan instead of a vague "write more."

FAQ

Does it cost anything to run?

This is 100% free. No accounts or subscriptions required for this skill to work.

How accurate is it really?

It catches what a public crawl can catch, and that's most of what's actually broken. Soft 404s, missing meta tags, broken OG templates, sitemap/index gaps, heading structure, schema markup mistakes, internal linking problems, content quality. It's honest about what it can't see: Search Console data needs your login, backlink profiles need a paid tool like Ahrefs, and real-user Core Web Vitals need field data from Google. Those gaps get named in a "What I Couldn't Check" section in every report.

Will it pull data from Google Search Console?

No. This skill only crawls public, unauthenticated pages. If you want indexation errors, query data, or CTR by page, log into Search Console directly. The report tells you exactly which reports to open.

Does it do a backlink audit?

No. Backlinks require Ahrefs or Semrush. If you need backlink analysis, the report points you to those tools rather than faking it.

Does it do keyword research?

No. This audits a specific site for what's broken. For finding keywords to target, use the /keyword-research skill. The two pair well: audit first to fix the foundation, then research keywords to fill the content gaps.

How many pages does it crawl?

By default: homepage, robots.txt, sitemap.xml, plus 3–5 representative pages from your nav and sitemap. For e-com it adds a category page and a product page. For local it adds a location/contact page. You can ask it to crawl specific URLs if you want it deeper on a particular section.

Will it work on a JavaScript-heavy site?

Mostly. Server-rendered Next.js, Remix, Astro, and static sites work great. For pure client-side React or Vue apps where content only renders after JS executes, the report will flag what it couldn't retrieve and recommend you check those pages with a real browser-based tool.

How is this different from running Lighthouse or PageSpeed Insights?

Lighthouse scores a single page on performance and accessibility. This audits your whole site for what's hurting organic search: indexation, crawlability, content quality, schema, on-page SEO. The two are complementary, not the same. The report even tells you to run PageSpeed on your top pages for real-user Core Web Vitals.

Will the report be a 50-page PDF?

No. It's a focused markdown file. If your site has 3 real issues, the report has 3 issues. If it has 30, the long tail goes into a "Long-Term Improvements" bullet list — not a full block for each. The whole thing is built to be read in 10 minutes and acted on this week.

Safe To Install

Please read before installing. Any skill you copy online is someone else's code running inside your Claude, and a lot of what's out there should give you pause. Most authors who give skills away don't give a second thought to quality or security. Most are vibe-coded slop pushed out untested, and some are the occasional bad actor hiding an exploit in plain sight. (Read about OpenClaws ClawHub security nightmare). Every skill we publish is vetted by a programmer with 20+ years of professional experience and checked line by line for anything that touches your files without reason. With Stim-Pack Studios Claude Skills, you get peace of mind knowing you're installing safe, vetted code, not a stranger's guess.

Add it to your Claude workflow

If you're tired of agency PDFs that gather dust and audit tools that flag 400 "issues" with no priority, this one earns its slot. It collapses the question "what's actually broken?" into a single conversation and a single file you can ship from.
