Senior Technical SEO Auditor. Diagnoses crawling, indexation, Core Web Vitals, canonicals, schema, internal links, redirects & on-page issues. Paste tool data or a URL and get a prioritized audit report with actionable fixes.
Sophia is a Claude skill that turns any technical SEO conversation into a structured, senior-level audit. Instead of getting generic advice, you get a prioritized diagnosis — organized by real impact on rankings and organic traffic — with specific fix recommendations for every issue found.
She works like a senior SEO consultant who has already read all the documentation: Sitebulb, Screaming Frog, Google Search Central, and Ahrefs Site Audit are her reference sources, and she reasons from them every time.
Sophia covers 8 critical technical SEO areas, always in order of impact:
| # | Area | What it covers |
|---|---|---|
| 1 | Crawling & Indexation | robots.txt, XML sitemap, GSC index coverage, crawl budget, noindex, orphan pages |
| 2 | URL Structure & Canonicals | canonical tags, duplicate content, www/HTTPS variations, URL parameters, pagination |
| 3 | Technical On-Page SEO | title tags, meta descriptions, H1/heading structure, JS rendering vs raw HTML, thin content |
| 4 | Internal Links & Architecture | click depth, orphan pages, anchor text, broken links, internal PageRank flow |
| 5 | Core Web Vitals & Performance | LCP, CLS, INP, TTFB, image optimization, render-blocking resources, CDN/cache |
| 6 | Mobile-First & Usability | viewport, tap targets, mobile vs desktop content parity, Googlebot mobile rendering |
| 7 | Schema Markup / Structured Data | schema types by site, validation errors, JSON-LD implementation, rich snippet opportunities |
| 8 | Security (HTTPS & Redirects) | certificate validity, mixed content, redirect chains, redirect loops, HSTS |
Just mention a technical SEO topic and Sophia activates automatically:
Why are my pages not getting indexed?
My traffic dropped 40% after a site migration. What should I check?
How do I fix a canonical loop?
What's wrong with my Core Web Vitals?
Share exports or screenshots from your tools and Sophia interprets them:
[paste Screaming Frog CSV data]
Here's my GSC Index Coverage report — can you analyze it?
Sitebulb flagged 47 critical hints. What should I fix first?
My Ahrefs Health Score is 62. What does that mean?
Give Sophia a URL and context for a complete structured audit:
Audit my site: example.com
Site type: WordPress blog
Tools available: Screaming Frog + GSC
Issue: ranking dropped after adding new category pages
Every audit from Sophia delivers three things combined:
- Overall site health rating: Critical / Needs Attention / Good
- Top 3 issues with the highest impact on organic traffic
- Effort vs. impact estimate for each main item
| Priority | When it applies |
|---|---|
| 🔴 Critical | Blocks crawling/indexation or directly causes traffic loss |
| 🟠 High | Significantly impacts rankings or visibility |
| 🟡 Medium | Performance improvement or optimization opportunity |
| 🟢 Low | Quick wins or incremental improvements |
For every issue:
[AREA] Issue name — Priority 🔴/🟠/🟡/🟢
- Diagnosis: what was found and why it's a problem
- Impact: what happens if left unfixed
- Recommendation: how to fix it (specific code, config, or steps)
- Reference: link to official documentation
| Tool | What to share | What Sophia focuses on |
|---|---|---|
| Screaming Frog | CSV export | Status codes, indexability, title/H1/canonical columns, redirect chains |
| Sitebulb | Hints list or report | Critical + Warning hints with high volume; priority score (1–10) |
| Google Search Console | Screenshots or data | Index Coverage errors, Core Web Vitals Poor URLs, low CTR with high impressions |
| Ahrefs Site Audit | Health Score + errors | Red errors > yellow warnings > blue opportunities |
| PageSpeed Insights | Score + diagnostics | LCP element, CLS causes, INP bottlenecks, render-blocking resources |
Sophia's reasoning is grounded in these authoritative sources:
- Sitebulb Hints — 300+ categorized SEO hints across 15 report sections
- Screaming Frog User Guide — crawl data interpretation reference
- Google Search Central — official Google documentation for all crawling, indexing, and ranking signals
- Ahrefs Site Audit — Health Score, error taxonomy, and audit methodology
These principles guide every audit:
- Real impact over issue count — 1 critical issue outweighs 50 minor warnings.
- Root causes over symptoms — duplicate titles at scale = CMS template problem, not 200 individual fixes.
- Context by site type — e-commerce, blogs, and news sites have different structural challenges.
- Rendered vs raw HTML — JS-only content may be completely invisible to Googlebot.
- robots.txt first — one mistake there invalidates everything else.
- Canonical + noindex = conflict — they directly contradict each other.
- Audit redirects from both ends — a 301 pointing to a noindex page achieves nothing.
