The paraphrase problem
Classic search sent buyers to your website, where you controlled every word. Generative engines answer on your behalf. They compress your product into two sentences, state your pricing from memory, and summarize your ideal customer, all without you in the room. Most of the time the paraphrase is broadly right. When it is wrong, it is wrong at the exact moment a buyer is forming a shortlist.
In the brand scans we run, inaccuracies are not rare edge cases. We routinely flag answers that quote pricing from two plans ago, describe features that were deprecated, attach brands to categories they exited, or confidently state a compliance posture the company never claimed. Each of those errors is delivered in the engine's authoritative voice, which makes it more persuasive than any competitor's ad could ever be.
Where inaccuracies come from
Three sources dominate. First, stale corpus: model training data lags reality, so anything that changed recently (pricing, packaging, product names) is at risk of being answered from an old snapshot. Second, third-party drift: engines lean on aggregators and articles, and if those describe you incorrectly, the engine inherits the error with none of the original's caveats.
Third, plausible interpolation. When retrieval comes back thin, models fill gaps with what is statistically likely for a company shaped like yours. That is how a mid-market platform gets described with an enterprise price tag, or a security tool gets credited with certifications its competitors hold. Nothing 'lied'; the model just completed a pattern, and the pattern was not you.
The cost of a wrong answer
Wrong pricing suppresses demand invisibly: a buyer told you cost $999 a month when your Starter plan is $99 simply never clicks through, and no analytics event records why. Wrong capability claims do the opposite damage: they create demos that open with a feature you do not have. And wrong audience framing ('built for enterprises') filters out exactly the buyers you built the product for.
The compounding effect is the dangerous part. Engines corroborate against prior answers and against content that quoted prior answers. An error that stands uncorrected gets restated, scraped, and re-cited until it hardens into consensus. Accuracy problems age like debt, which is why detection speed matters more than most teams assume.
Monitoring for accuracy, not just presence
Most AI-visibility measurement stops at 'were we mentioned.' Accuracy monitoring asks the second question: 'was what they said true?' In Citationly, Brand Pulse compares every scanned answer against your canonical brand facts (pricing, plans, features, integrations, positioning) and raises an accuracy flag when an answer contradicts them, with the offending platform, prompt, and cited sources attached.
The flags are triaged by severity. A wrong founding year is cosmetic; wrong pricing on a high-intent comparison prompt is a revenue incident. Alert routing reflects that: cosmetic drift lands in a weekly digest, while material misstatements on commercial prompts notify the team immediately.
Correcting the record
Corrections work through sources, because engines believe sources. Fix the canonical facts on your own domain first: a clearly structured, dated pricing page is the single highest-leverage accuracy asset you can ship. Then chase the cited third parties: the citation log tells you exactly which stale article or unclaimed profile the engine leaned on, which turns 'fix the internet' into a short, ordered task list.
Then verify on a cadence. Re-run the affected prompts, watch the flag clear platform by platform, and keep the fact base in Knowledge Vault current so the next product change propagates before the engines notice on their own. Presence gets you into the answer; accuracy decides whether the answer sells for you or against you.
