Technical SEO audit in 2026
The 42 checkpoints we apply in every SEO audit: technical, editorial, authority and AEO. eXprimeNet operational method.
An SEO audit in 2026 must cover 4 blocks: (1) technical (speed, Core Web Vitals, crawlability), (2) editorial (content, titles, headings), (3) authority (backlinks, mentions, E-E-A-T), and (4) AEO (schema, TL;DR, llms.txt). The first 2 blocks yield 60% of the result; the last 2 are the differentiator.
What is an SEO audit?
An SEO audit is the systematic analysis of a website’s status against the factors that determine its visibility in search engines (Google, Bing) and answer engines (Perplexity, ChatGPT, Gemini).
The deliverable is a report with prioritised findings (by impact × effort), implementation roadmap and competitor benchmarks. A professional audit takes 25-60 hours and uncovers 15-40 impactful checkpoints.
