Aetos SEO vs Yoast
Yoast writes your titles, meta, sitemaps, and schema. Aetos audits everything Yoast can't show you — including AI-readiness, GEO eligibility, and 200+ technical signals. Different layers. Most serious sites run both.
Pick Aetos if you want
- ✓ 200+ checks across 17 categories, site-wide (vs Yoast's ~40 on-page)
- ✓ AEO + AIO + GEO scoring
- ✓ JSON export for a prioritized ChatGPT/developer fix plan
- ✓ 4-AI-reviewer audited security model
Best move: run both. Yoast writes the SEO, Aetos audits whether what got written is actually working.

FAQ
Aetos vs Yoast — common questions
Is Aetos SEO a replacement for Yoast?
No. Yoast writes your titles, meta descriptions, sitemaps, and schema. Aetos does not do that. Aetos audits whether your site (whatever wrote the SEO) is technically sound, AI-readable, and eligible for citations in ChatGPT, Claude, Perplexity, and Google AI Overviews. They cover different jobs — most serious WordPress sites should run both.
Can I use Aetos and Yoast on the same site without conflicts?
Yes. Aetos is a read-only audit layer — it does not write to the same database tables Yoast uses for its post meta. We tested compatibility against Yoast 24.x as part of our pre-release audit. No conflicts observed in 7 rounds of multi-model review.
Yoast already shows me a green/orange/red SEO score. What does Aetos add?
Yoast scores ~40 mostly on-page authoring signals: keyword density, meta length, internal links in that post. Aetos scores 200+ site-wide technical, AEO, AIO, and GEO signals: schema validation, redirect chains, AI bot policy in robots.txt, citation density, llms.txt, structured data graph integrity, and 60+ more. Different layer of the same problem.
When should I pick Yoast Premium over Aetos Pro?
Pick Yoast Premium if your main need is AI title/meta generation, internal-link suggestions, or 4xx redirect management built into the post editor. Pick Aetos Pro if your main need is an honest audit of how AI-ready and technically clean your site is, plus a JSON export you can review with ChatGPT or your developer to draft a prioritized fix plan. They are complementary, not competing.
Is the comparison on this page biased?
It is by Aetos, so we have an obvious bias. We compensate by (a) verifying Yoast features on yoast.com on the date below, (b) crediting Yoast for everything they actually do — including features we do not, (c) footnoting any soft superlatives, and (d) inviting Yoast to flag anything inaccurate at admin@nsrelmtagr.com. We will correct and date the change.
