How FixAEO compares

The active AEO tooling market in 2026 includes FixAEO (free 19-tool catalog with 6-engine scanner), Profound (enterprise agent platform, 9 engines), AEO Engine (done-for-you agency from $797/mo), AEO Checker (multilingual scanner from $5/mo), Otterly ($29/mo GEO research with pre-publish scoring), Peec AI (paid analytics with Looker/BI integrations), and SearchFit (plugin-first via Claude/WordPress/Shopify). Each targets a different buyer — pick by your budget, engine coverage needs, and whether you want self-serve tools or done-for-you work.

FixAEO has the lowest entry point at $0/month — the 19-tool free tier is genuinely usable without signup or credit card, including a 1-engine scanner. AEO Checker starts at $5/month for its multilingual scanner. Otterly is $29/month. AEO Engine starts at $797/month because it's a done-for-you retainer, not a self-serve product. Profound and Peec AI use sales-led pricing without published rates.

FixAEO is built for solo founders and SMBs — free tier with no signup, $19/month Pro for higher volume, no sales calls or annual contracts. AEO Checker is a viable alternative at $5/month if you specifically need its multilingual scanner. Avoid enterprise platforms like Profound or done-for-you agencies like AEO Engine at this stage — the surface area is overkill for a single-site solo operation.

Profound is the strongest enterprise fit — 9-engine coverage including Microsoft Copilot, Meta AI, and Google AI Overviews; autonomous agents handling content and brand work; real prompt-volume data from millions of AI queries; and procurement-ready contracts (SOC 2, SSO, DPAs). Peec AI is a fit for marketing teams that need BI integrations (Looker Studio, CSV exports). FixAEO and AEO Checker are self-serve and don't currently offer enterprise procurement features.

Yes. FixAEO publishes 19 tools free during early access, including schema generators, llms.txt and robots.txt generators, sitemap validators, and a 6-engine AI visibility checker. Profound offers a free one-shot AEO report and a free agent trial, but the platform itself is paid. Otterly offers a limited trial. Most other tools (Peec AI, AEO Engine, SearchFit Pro) are paid-only.

Profound covers 9 surfaces: ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, Microsoft Copilot, Meta AI, and Google AI Overviews. FixAEO covers 6 (ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek). Most other tools cover 2–4 engines, typically the live-search-enabled ones (ChatGPT, Perplexity, Gemini). If 100% engine coverage is a hard requirement, Profound wins on breadth; if Grok and DeepSeek matter and Copilot doesn't, FixAEO is sufficient.

Three questions: (1) What's your budget? Under $50/month points you at FixAEO or AEO Checker; $50–500/month opens Otterly and Peec AI; $500+/month opens AEO Engine and Profound. (2) Self-serve or done-for-you? Self-serve = FixAEO, AEO Checker, Otterly, Peec AI, SearchFit. Done-for-you = AEO Engine. Enterprise platform with services = Profound. (3) Which engines matter? If you need Copilot, Meta AI, or Google AI Overviews, only Profound covers them; the rest focus on the big six.

SEO optimises for ranking in Google's blue links — title tags, backlinks, keyword density. AEO optimises for being cited inside AI-generated answers from ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews — structured data, definitional paragraphs, llms.txt, and AI-crawler-aware robots.txt. The work overlaps (clean HTML, fast pages, semantic markup matter for both) but the signals and priorities differ. Most teams now need both.
