What you review with ChatGPT, Claude, or your developer.
One click and Aetos exports one compact, redacted JSON file containing everything below. Use it with a developer, ChatGPT, Claude, or a project workspace to draft a prioritized fix plan from real site context.
Site snapshot
Home URL, name, description, language, timezone, SSL status, permalink structure, and whether the site is set public/indexable.
Every audit finding
Each check result with severity (high/med/low/info), the affected URLs, why it matters, and step-by-step fix.
Top 10 priority actions
The highest-impact open issues, pre-ranked, each with its affected URLs and fix steps — so the AI starts where it counts.
Runtime + tech stack
WP/PHP version, theme (name, version, parent), every installed plugin with version + active state, server software, caching layer, and CDN.
SEO plugin config
Detected Yoast / Rank Math / AIOSEO / cache settings (API keys redacted), plus an options scan for any other active plugin.
Content inventory + samples
Post-type and taxonomy counts, a list of up to 1000 posts/pages (newest first) with dates, and content excerpts with each post's SEO title + description.
Crawl snapshot
Up to 200 crawled URLs with status code, canonical, noindex, H1/H2 count, word count, images + missing-alt, CSS/JS counts — plus robots.txt, sitemaps, and llms.txt presence.
WooCommerce + multilingual
Store currency, product + category counts (if WooCommerce), and WPML / Polylang language setup.
AI profile + usage guide
A ready system prompt and a per-section guide, so any chat (ChatGPT or Claude) reads the bundle correctly on the first message.
Works with the tools you already use
Aetos pulls real Core Web Vitals from Google field data, and detects whether your measurement tools are set up correctly. Reading data directly from Search Console, GA4, and Clarity as findings is coming soon — and it only ever reads, never writes, so it can't break a configuration you've already tuned.
PageSpeed Insights / Google CrUX
ActiveUses Google field data to measure Core Web Vitals (LCP, INP, CLS) on your top pages. Works without an API key; add one for higher quota.
Google Search Console
DetectsChecks whether GSC is connected and flags it if missing. Reading its data directly (CTR, queries, pages) as findings is coming soon.
Google Analytics 4 / GTM
DetectsDetects whether GA4 or Tag Manager is installed and recommends the right setup. Reading traffic + engagement data directly is coming soon.
Microsoft Clarity
DetectsDetects whether Clarity (free heatmaps + session recordings) is present and suggests adding it so you can see UX friction.
Yoast SEO compatibility
CompatibleDetects when Yoast is active, skips the audits we'd duplicate (schema/sitemap), and flags conflicts.
Rank Math compatibility
CompatibleSame as Yoast — auto-defers overlap-prone modules and flags schema collisions.
WP Rocket compatibility
CompatibleReads cache state and surfaces cache-vs-audit-finding inconsistencies.
