FAQ
Aetos vs Yoast — common questions
Is Aetos SEO a replacement for Yoast?
No. Yoast helps create and optimize titles, meta descriptions, sitemaps, schema, and content. Aetos evaluates whether the resulting site is technically sound and exposes the on-site signals used by search and AI systems. It does not guarantee rankings or citations. They cover different jobs and can run together.
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 gives real-time SEO and readability guidance while you write and now includes AI-focused features such as llms.txt and AI Brand Insights. Aetos evaluates 200+ site-wide technical, AEO, AIO, and GEO signals after implementation, including schema validity, redirect chains, crawler policy, and structured-data integrity. They measure different layers 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 support@aetosseo.com. We will correct and date the change.
