Covers Claude / Grok / DeepSeek
Otterly skips these three. If your audience uses any of them, that's a gap.
Covers Google AI Overviews / AI Mode / Copilot
Otterly's win. We don't query these surfaces yet.
Pre-publish citation scoring
Otterly's signature feature — score a draft before publishing. We don't have an equivalent.
Published GEO experiments / research
Otterly publishes data-backed GEO research; we don't yet have that authority surface.
Funnel-specific segmentation (BoFu / Non-Branded)
Otterly has tag-based filtering for funnel stage; ours is flat per-scan.
Number of free interactive tools
Ours: 19 tools across 4 categories. Theirs: 4 free GEO tools (AI keyword research, Query Fan Out, GEO Content Check, AI Crawler Simulation).
Spec-compliant llms.txt
We publish ours + ship a generator. Theirs isn't publicly documented.
Explicit AI bot allows in robots.txt
Both treat AI crawlers as first-class. We document our exact allowlist publicly.
Server-side rendered (crawler-friendly)
We SSR everything. Their app is interactive — fewer raw HTML signals for AI crawlers.
Public sample report
Ours at /aeo-report/. Theirs is gated behind trial signup.
Frequently asked questions
What's the difference in approach?
Otterly is a focused GEO monitoring platform — track brand mentions, citations, and share of voice across 6 AI engines, with a pre-publish content scorer that predicts citation potential. They invest heavily in published GEO experiments to establish research authority. FixAEO is a broader free toolkit — 19 utilities (generators, planners, audits, validators) plus a 6-engine scanner. Different bets: research-depth vs tool-breadth.
Which is cheaper?
FixAEO. Our free tier covers all 19 tools — Pro is $19/mo for higher-volume scans + recurring tracking. Otterly starts at $29/mo (after a 14-day free trial) and goes up from there. If you're testing AEO or solo, the free gap matters; if you want continuous tracking, both have paid tiers in similar range.
Which one covers more AI engines?
Roughly tied — both cover 6. Otterly lists ChatGPT, Perplexity, AI Overviews, AI Mode, Gemini, and Copilot. FixAEO covers ChatGPT, Claude, Gemini, Perplexity, Grok, and DeepSeek. Theirs adds Google AI Overviews / AI Mode / Copilot; ours adds Claude / Grok / DeepSeek. Depending on your audience, one mix is more relevant than the other.
Does Otterly have features we don't?
Three notable ones. (1) Pre-publish citation scoring — feed in a draft, get a 'will this be cited' score before publishing. We don't have that. (2) Funnel-specific filtering (Bottom-of-Funnel tags, Non-Branded segmentation) for targeted optimization. (3) Their published GEO Experiments library (e.g., Markdown vs HTML, schema markup impact) is genuinely useful and establishes research credibility we don't have.
What does FixAEO do better than Otterly?
Four concrete things. (1) Free forever — Otterly's free 14-day trial expires; ours doesn't. (2) Wider tool catalog organized by job-to-be-done — 4 generators, 6 planning tools, 5 audits, 3 validators vs Otterly's monitoring-focused product. (3) Coverage of Claude / Grok / DeepSeek that Otterly skips. (4) Public sample report at /aeo-report/ that anyone can inspect before signup.
Which one is better for content teams writing new pages?
Otterly — their pre-publish citation scorer is built for exactly that workflow. Score a draft, iterate, publish. We help on the pre-publish side via Schema Generator + llms.txt Generator + Meta Description Generator, but we don't predict citation potential the way they do.
Which one is better for one-off site audits?
FixAEO. Type a URL, get a 6-engine scan + 10-check audit in 3 minutes, no signup. Otterly's product is built for continuous monitoring of a tracked site, not one-shot audits — you'd start a trial, configure it, then evaluate.
Can I use both?
Yes — they're more complementary than competitive. Use FixAEO for the utility catalog (generators, llms.txt, robots.txt, validators, one-shot audits) and quick scans. Use Otterly for continuous tracking + their pre-publish content scorer. Different stages of the AEO workflow.
