Disclosure We build SellOnLLM. Peec feature and pricing notes reflect public positioning; verify on peec.ai (or their current domain) before purchasing.
Quick verdict
- Pick SellOnLLM for a free no-signup check, on-page AI Readiness in Chrome, Shopify AI traffic, and ~$10/mo monitoring + competitor page watch.
- Pick Peec if you want a dedicated GEO visibility platform as your system of record for prompts and generative-engine share-of-voice—and your budget matches that category.
- Not mutually exclusive: use SellOnLLM to diagnose pages and share a free report; use Peec (or similar) when you need suite-scale GEO tracking across a large prompt set.
Side-by-side

| Ideal buyer | Solo SEO, founder, Shopify brand, freelancer | Growth / SEO teams buying a GEO system of record |
Where Peec wins
If your RFP says “GEO platform,” Peec-style products are built for that language: prompt libraries, generative-engine visibility, and team reporting. SellOnLLM will not claim to replace every GEO suite feature on day one—especially large multi-brand prompt matrices.
Where SellOnLLM wins
- Speed to insight. Paste a domain on sellonllm.com, get a score and citations snapshot without sales friction.
- Audit ↔ visibility loop. The Chrome extension connects “why this page fails AI readiness” to “do engines mention us?”
- Price for the long tail. Most brands that bounce after one scan never needed a suite—they needed a free answer. We price the paid layer for that reality.
- Merchant stack. Visibility plus ecommerce AI tooling in one product family.
Common mistakes when comparing
- Equating “AI visibility” with one chart. Mentions, citations, readiness, and Shopify referral traffic are different signals—see our why track AI visibility guide.
- Buying a suite before a baseline. Run a free check first; many teams discover their score is 0 on buyer prompts and need content/structure work more than dashboards.
- Ignoring the fix workflow. Measurement without an audit loop is how listicle tools collect dust.
