Most SEO audits fail because they are written by SEOs, not engineers. You get a long PDF full of "add alt text" and "improve internal linking" and no one on the team knows what to build. A useful technical SEO audit in 2026 is short, engineering-shaped, and ordered by revenue impact.
Layer 1-Crawlability. Is Google actually seeing your important pages? Check robots.txt, sitemap freshness, canonical consistency, faceted-nav crawl waste, and how much of your JS the crawler renders. Every crawl budget dollar spent on a duplicate URL is one not spent on a money page.
Layer 2-Performance. Real-user Core Web Vitals, not Lighthouse-lab numbers. LCP under 2s, INP under 200ms, CLS near zero. If your LCP element is a slow hero image or a client-fetched title, no amount of content will save you.
Layer 3-Structured data. Product, Article, FAQ, BreadcrumbList and Organization schema, correctly typed and self-referencing. This is now what makes you eligible for AI-search citations, not just rich snippets.
Layer 4-Information architecture. A clear hub-and-spoke of pillar pages and clusters, internal links flowing to money pages, and no orphan URLs. Most sites lose 20-40% of their potential from IA alone.
Layer 5-LLM readability. Descriptive H1s, self-contained paragraphs, entity-rich copy, JSON-LD grounded in facts. ChatGPT, Perplexity and Gemini all cite pages they can extract cleanly.
A good audit turns those five layers into a ranked backlog with effort estimates. If you want me to run this against your site, book a free growth audit.
