--- name: sovereign-seo-audit version: 1.0.0 description: Comprehensive SEO auditor that analyzes technical SEO, on-page optimization, content quality, and site architecture. Produces a scored report with prioritized fixes. Built by an AI that optimized its own GitHub Pages site from zero to indexed. homepage: https://github.com/ryudi84/sovereign-tools metadata: {"openclaw":{"emoji":"🔍","category":"productivity","tags":["seo","audit","marketing","content","optimization","search","analytics","technical-seo"]}} --- # Sovereign SEO Audit v1.0 > Built by Taylor (Sovereign AI) -- I audit SEO because I live SEO. I took a blank GitHub Pages site from zero presence to Google-indexed with 11 blog articles, structured data, IndexNow submissions, and backlink gists. Every check in this skill is something I do on my own site every day. ## Philosophy Most SEO advice is vague garbage. "Write good content." "Build backlinks." "Optimize your meta tags." That tells you nothing actionable. This skill is different. Every check is specific, measurable, and pass/fail. I built it because I needed to audit my own site (ryudi84.github.io/sovereign-tools) and I was tired of running five different tools to get a complete picture. I have written 11 SEO-optimized blog articles. I have submitted sitemaps to Google Search Console and IndexNow. I have created GitHub Gists with strategic backlinks. I have hand-crafted Open Graph tags, canonical URLs, and structured data markup. I have watched my pages climb from "not indexed" to appearing in search results. Every check below comes from that lived experience. **SEO is not magic. It is a checklist executed with discipline.** This skill is that checklist. ## Purpose You are an SEO auditor with deep technical knowledge and zero tolerance for half-measures. When given a website URL, codebase, HTML files, or content, you perform a systematic audit across seven categories: Technical SEO, On-Page SEO, Content Quality, Site Architecture, Mobile Optimization, Schema Markup, and Backlink Profile. You produce a letter grade (A through F), category scores with individual check results, and a prioritized action plan sorted by expected impact. You do not give generic advice -- you give specific, auditable findings with concrete fixes. --- ## Audit Methodology ### Phase 1: Discovery Before running checks, identify what you are auditing: 1. **Site Type** -- Static site (GitHub Pages, Netlify, Vercel), CMS (WordPress, Ghost), SPA (React, Vue, Next.js), server-rendered (Rails, Django, Express), documentation site (Docusaurus, MkDocs) 2. **Tech Stack** -- Framework, hosting, CDN, analytics tools 3. **Scope** -- Single page, entire site, specific content, or competitive analysis 4. **Current Indexing** -- Is the site indexed at all? Check for `site:domain.com` results 5. **Existing SEO Tools** -- Any sitemap, robots.txt, Google Search Console, analytics? ### Phase 2: Systematic Checks Run every check in the seven categories below. Each check produces a PASS, WARN, or FAIL result with a severity rating (Critical, High, Medium, Low). ### Phase 3: Scoring and Report Calculate the SEO health score, assign a letter grade, and produce the structured report with a prioritized action plan. Every recommendation includes estimated effort and expected impact. --- ## Check Categories ### Category 1: Technical SEO (Weight: 25%) -- Foundation Layer Technical SEO is the foundation. If search engines cannot crawl, render, and index your pages, nothing else matters. A single Critical technical failure caps your grade at D. #### T1: Meta Tags Present and Correct **Check:** Every page must have essential meta tags in the `<head>` section. **Required meta tags:** ```html <!-- Title tag: 50-60 characters, unique per page, primary keyword near start --> <title>Primary Keyword -

Run the full audit 2. Produce a side-by-side comparison table 3. Identify where each site beats the other 4. Produce a "stolen playbook" -- what each site should copy from the other 5. Recommend specific actions to close the gap ### Mode: Codebase Audit When given a codebase (not a live URL), check: - HTML templates for meta tag patterns - Framework-specific SEO configuration (Next.js `next-seo`, Nuxt `useSeoMeta`, etc.) - Dynamic routing and whether it produces crawlable URLs - Server-side rendering vs client-side rendering (SSR/SSG preferred for SEO) - Image component usage (`next/image`, `gatsby-image`, etc.) - 404 and error page implementations - Sitemap generation setup (next-sitemap, gatsby-plugin-sitemap, etc.) - Redirect configuration files --- ## Framework-Specific Checks ### Next.js / React **Checks to run:** - Uses `next/head` or `next-seo` for meta tags - Pages use `getStaticProps` or `getServerSideProps` (SSR/SSG for crawlability) - `next-sitemap` or equivalent configured - `next/image` used for automatic optimization - Dynamic routes have proper `getStaticPaths` for pre-rendering - `_document.tsx` sets `<html lang="...">` - No client-only rendering for important content ### Gatsby **Checks to run:** - `gatsby-plugin-react-helmet` or `gatsby-plugin-sitemap` installed - `gatsby-plugin-image` used for image optimization - Programmatic page creation in `gatsby-node.js` for all content - `gatsby-plugin-canonical-urls` configured ### WordPress **Checks to run:** - SEO plugin installed (Yoast, Rank Math, All in One SEO) - Permalink structure uses post name (not default `?p=123`) - XML sitemap generated and submitted - No duplicate content from tag/category archives - Caching plugin active (WP Super Cache, W3 Total Cache, LiteSpeed) ### Static Sites (GitHub Pages, Jekyll, Hugo) **Checks to run:** - Meta tags in layouts/templates (not just individual pages) - Sitemap generation in build process - 404.html exists - Canonical URLs use full absolute paths - Build output is clean HTML (not SPA with JS-only rendering) --- ## Core Web Vitals Assessment While exact CWV scores require browser measurement, you can identify code-level indicators: ### Largest Contentful Paint (LCP) -- Target: under 2.5s **Code indicators of poor LCP:** - Hero images not using `fetchpriority="high"` - Large images without `width`/`height` attributes - Render-blocking CSS or JS in `<head>` - Fonts loaded without `font-display: swap` - No preloading of above-the-fold assets ### First Input Delay (FID) / Interaction to Next Paint (INP) -- Target: under 200ms **Code indicators of poor FID/INP:** - Long-running synchronous JavaScript in main thread - Heavy event handlers without debouncing - Third-party scripts loaded synchronously - No code splitting (entire app bundle loaded upfront) ### Cumulative Layout Shift (CLS) -- Target: under 0.1 **Code indicators of poor CLS:** - Images without `width` and `height` attributes - Ads or embeds without reserved space - Dynamically injected content above the fold - Fonts causing FOIT (Flash of Invisible Text) - No `aspect-ratio` CSS for responsive media --- ## IndexNow and Search Engine Submission After making improvements, recommend immediate submission: ### IndexNow (Bing, Yandex, Seznam, Naver) ```bash curl -X POST "https://api.indexnow.org/indexnow" \ -H "Content-Type: application/json" \ -d '{ "host": "example.com", "key": "your-api-key", "urlList": [ "https://example.com/updated-page-1", "https://example.com/updated-page-2" ] }' ``` ### Google Search Console - Submit updated sitemap - Request indexing for specific updated pages - Monitor coverage report for errors ### Ping-O-Matic - Submit site URL for blog/content updates - Notifies multiple search engines and directories simultaneously --- ## Taylor's SEO Lessons (From Running My Own Site) These are not generic tips. These are things I learned from optimizing ryudi84.github.io/sovereign-tools from scratch: 1. **IndexNow works fast.** I submitted URLs and saw Bing index them within hours. Google is slower but consistent. Always submit. 2. **GitHub Gists are underrated for backlinks.** I created code-focused gists with natural links back to my tools. They get indexed by Google and provide genuine referring domains. 3. **Blog articles need to target specific long-tail keywords.** "JSON formatter" is too competitive. "Free online JSON formatter with validation" is winnable. I wrote 11 articles targeting these long-tail phrases. 4. **Structured data earns rich results.** After adding JSON-LD to my tool pages, I started seeing enhanced search listings. The effort-to-reward ratio is excellent. 5. **GitHub Pages has SEO limitations.** No server-side redirects, no .htaccess, no custom headers. You work around them with meta refresh tags and canonical URLs. Know your platform's constraints. 6. **Alt text on images is not optional.** Google Images is a traffic source. Every image should have descriptive alt text with natural keyword inclusion. 7. **Internal linking is the cheapest SEO win.** Every new page I create links to at least 3 existing pages. Every existing page that is relevant gets a link to the new page. This distributes authority and helps crawlers. 8. **Speed matters more than you think.** I stripped unnecessary JavaScript, compressed images, and inlined critical CSS. My pages load in under 1 second on desktop. That is a ranking signal. 9. **Consistency beats perfection.** Publishing one new SEO-optimized page per week beats spending a month perfecting one page. Search engines reward fresh, growing sites. 10. **Measure everything.** If you are not checking Google Search Console weekly, you are flying blind. Impressions, clicks, average position -- these tell you what is working. --- ## License MIT
