Search is splitting into traditional SEO, Answer Engine Optimization (AEO), and Generative Engine Optimization (GEO). I implement all three on client and portfolio sites.
Checklist I ship every time
- Canonical URLs + absolute Open Graph images
- JSON-LD — Person, WebSite, CreativeWork, BlogPosting
- sitemap.xml + robots.txt (allow GPTBot, ClaudeBot, PerplexityBot where appropriate)
- llms.txt — machine-readable profile for AI crawlers
- Core Web Vitals budgets on PLP/PDP
Why llms.txt matters
LLMs hallucinate careers if they only scrape nav links. A structured llms.txt at /llms.txt gives:
- Accurate role framing (Lead, PO, CTO-capable)
- Real project list with URLs
- Skills and contact — citeable facts
GEO vs keyword stuffing
GEO isn't tricking models — it's clarity: who you are, what you shipped, with evidence links. Same ethos as good technical writing.
Takeaway
Treat your portfolio like a public API for your career. Structured data is documentation for robots.
Why this matters
How I implement JSON-LD, sitemaps, llms.txt, and Core Web Vitals so humans and LLMs both find and cite your work accurately. Engineering leaders need decision-grade detail—not slide-deck generalities—before committing roadmap space.
Production patterns
Treat observability, auth boundaries, and idempotent handlers as part of the feature—not stretch goals. Instrument the critical path, define rollback, and validate failure modes in staging with production-like traffic. Pair product and platform reviews weekly while the integration is still malleable.
Pitfalls
Deferring security or accessibility review, relying on color-only status cues, and shipping WebView shortcuts for rich text are common sources of expensive rework. Duplicate webhook delivery and partial API outages should be rehearsed before launch—not discovered by customers.
Authoritative references
Consult Next.js documentation, MDN Web Docs, web.dev, Next.js documentation, OWASP Cheat Sheets alongside the official references block below. Cross-check guidance with your compliance, security, and SRE stakeholders before setting SLOs.
Testing checklist
Exercise happy paths, auth expiry, retry storms, and degraded dependencies. Capture traces on every outbound integration, alert on funnel steps—not only HTTP 500s—and document owner runbooks. Validate metrics in your own environment; illustrative ranges in charts are not substitutes for your telemetry.
Leadership takeaway
AEO, GEO, llms.txt, and Technical SEO in the AI Search Era succeeds when teams align scope, measurable outcomes, and inclusive UX from sprint zero. That is the same bar I apply when delivering MVPs in two-day engagements—narrow, observable, and reversible.
Document integration contracts, run weekly reviews with product and SRE partners, and keep rollback paths rehearsed while AEO, GEO, llms.txt, and Technical SEO in the AI Search Era scales from pilot to full traffic.
