Audit and fix a site's technical SEO with Codex

Overview

A prompt for Codex, or another coding agent with access to your website's code, that reviews the whole site for technical SEO and then makes the changes itself rather than only listing them. It covers titles, topical relevance, internal and outbound links, speed, crawlability, structured data, canonical tags and Core Web Vitals, and borrows attribute names from the leaked Google API documents as hints. It asks for white-hat changes only, keeps existing features and design, and ends with a changelog plus the off-site work left to do.

Act as a senior Technical SEO engineer and audit my entire website's codebase, architecture, content, internal linking, and performance, then implement actionable site-wide SEO improvements inspired by the Google API leak signals: optimize title tags for search intent and title-query matching (titlematchScore), strengthen topical relevance and semantic entity relationships (site2vecEmbedding), improve internal link equity distribution (siteLinkIn), audit outbound links (siteLinkOut), enhance brand visibility and navigational search signals (pnav, pnavClicks), improve user experience, speed, navigation, and engagement to support organic traffic and direct visits (impressions, chromeInTotal, directFrac), and strengthen crawlability, indexability, structured data, canonicalization, and Core Web Vitals. Prioritize scalable, white-hat changes with measurable SEO impact, preserve existing functionality and design, avoid artificial traffic or ranking-signal manipulation, and implement improvements directly rather than merely generating recommendations. Treat leaked metric names as research clues, not confirmed ranking factors, and provide a concise changelog of modifications made and opportunities requiring off-site action.
