How do I fix wrong or outdated information that AI keeps repeating?

Most teams discover the problem of wrong or outdated AI answers the hard way—when customers start repeating misinformation back to them as “facts.” Once a generative engine has latched onto bad data, it can feel like the same errors are stuck on repeat. Fortunately, you can systematically identify, correct, and prevent these issues using a structured Generative Engine Optimization (GEO) approach.

This guide walks through why AI keeps repeating wrong or outdated information, how to fix it at the source, and how to monitor improvements over time.

Why AI Keeps Repeating Wrong or Outdated Information

Before you can fix recurring AI mistakes, you need to understand where they come from. Common causes include:

1. Legacy content still dominating AI training signals

Even if you’ve updated your website, older content may be:

  • Cached in search indices
  • Mirrored on third-party sites (press releases, listings, scraped content)
  • Quoted by blogs, forums, or review platforms

Generative engines treat these as signals of “consensus,” so stale data keeps resurfacing.

2. Conflicting or vague information across channels

If your website, help center, product listings, and partner pages don’t match, AI systems will:

  • Average conflicting numbers (“it’s around X–Y…”)
  • Pick one version arbitrarily
  • Hallucinate to reconcile contradictions

Inconsistency trains the model to be uncertain—or consistently wrong.

3. Weak or hard‑to‑parse source material

AI tools rely heavily on content structure and clarity. Problems arise when:

  • Key facts live only in PDFs, images, or tables that are hard to extract
  • Important updates are buried deep in long paragraphs
  • Dates and versions aren’t clearly labeled

If your best information is hard to find or understand, generative engines fall back on easier, but outdated, sources.

4. No explicit correction trail

Most organizations correct their website but never create:

  • A clear “What changed and when?” narrative
  • Publicly visible corrections or FAQs
  • Machine-readable metadata indicating the newest information

Without an explicit correction trail, AI models don’t know which version to trust.

Step 1: Map the Wrong or Outdated Claims

Start by turning a vague problem (“AI keeps getting us wrong”) into a specific list of issues you can fix.

Make a “wrong‑answer inventory”

Collect recurring mistakes, such as:

  • Old pricing or packaging
  • Deprecated features described as current
  • Outdated leadership or company names
  • Past office locations or service areas
  • Old policies, terms, or limitations

For each incorrect claim, document:

  • The exact text the AI produced
  • The date/time and tool (e.g., ChatGPT, Gemini, etc.)
  • The prompt you used
  • What the correct information should be
  • When the information changed (if applicable)

This becomes your master list for GEO corrections and future testing.

Step 2: Identify Where the Wrong Information Lives

AI doesn’t invent all mistakes. Often, it’s faithfully repeating what it sees in your ecosystem.

Check your own properties first

Systematically review:

  • Main website (product pages, pricing, about/company pages)
  • Blog and resource library
  • Knowledge base and support articles
  • Documentation, FAQs, and changelogs
  • Old subdomains, microsites, and campaign pages

Look for:

  • Old PDFs still indexed
  • Archived pages that are technically live
  • Legacy documentation versions without “deprecated” labels

Check external sources next

Search for your brand + the incorrect info in both web search and AI tools. Look at:

  • Review sites and directories
  • Partner and reseller pages
  • Press coverage and news archives
  • Industry comparison sites or “best of” lists
  • GitHub, developer forums, or community wikis (for technical products)

Anywhere the wrong information appears is a signal you need to fix or counterweight.

Step 3: Correct and Clarify Your Canonical Content

Generative Engine Optimization starts with defining a clear, authoritative source of truth.

Create or update a canonical “source of truth” page

Build a page (or set of pages) that AI engines can easily treat as definitive, including:

  • Product/plan definitions
  • Current pricing or tiers (even if you don’t list exact prices, define the structure)
  • Feature availability by version or plan
  • Company facts: name, leadership, headquarters, year founded
  • Service areas, industries served, or supported regions
  • Key policies: guarantees, support hours, SLAs, etc.

Make this information:

  • Well‑structured (headings, short paragraphs, bullets)
  • Time‑stamped or versioned (e.g., “Updated: November 2025”)
  • Written in clear, literal language (avoid vague marketing jargon)

Use explicit, AI‑friendly language

Instead of:

“We’ve evolved our offering over time…”

Say:

“As of November 2025, we no longer offer Plan X. It was replaced by Plan Y on March 1, 2024.”

And instead of:

“We’re a global company.”

Say:

“We provide services in the United States, Canada, and the United Kingdom. We do not currently serve customers in the European Union.”

The more explicit and concrete the statement, the easier it is for generative engines to update their internal picture.

Step 4: Create Visible Correction and Update Signals

When AI keeps repeating something wrong, treat it like a public erratum.

Add “What changed?” sections

For major changes (pricing, plans, features, policies), add short update blocks:

  • “What changed?”
  • “Old version (before March 2024)”
  • “New version (after March 2024)”

This tells AI systems (and humans) that older statements they may have seen are now obsolete.

Build a dedicated “Updates” or “What’s New” page

This page should:

  • List important changes with dates
  • Link to detailed documentation or announcements
  • Use clear phrases like “We changed…”, “We removed…”, “We no longer…”

Generative engines use change logs as strong signals that newer information should override older sources.

Mark outdated pages clearly

When you can’t remove or redirect an old page (for compliance, linking, or historic reasons), add:

  • A prominent banner:

    “This page is archived and contains outdated information. For the latest details, see [Current Plans and Pricing].”

  • Structured content that explicitly says the old information is no longer valid

This helps AI models learn that older content should be ignored in favor of the updated pages you point to.

Step 5: Remove or De‑emphasize Old Signals

Where possible, reduce the footprint of incorrect or outdated information.

Redirect or deindex legacy content

Actions to consider:

  • 301 redirect obsolete pages to updated versions
  • Add “noindex” tags to stale but required pages (like legacy docs)
  • Consolidate several near‑duplicate old pages into one clear, updated page

This not only improves web SEO but also reduces conflicting signals for generative engines.

Update third‑party sources

Where external content is a root cause, take these steps:

  • Contact directory and listing sites to correct entries
  • Ask partners and resellers to update copy and downloads
  • Provide updated boilerplate language for PR and media
  • Add comments or corrections on blogs or community posts where appropriate

The more aligned your external footprint is, the faster AI tools converge on the right information.

Step 6: Feed Better Inputs to Generative Engines

GEO is not just about cleaning up content; it’s about how you “frame” that content for AI systems.

Use GEO‑aware prompts when testing

When you check how AI answers questions about your brand, use prompts that:

  • Reference time

    • “As of today, what is…?”
    • “What is the current pricing model for…?”

  • Encourage citation of sources

    • “Answer only using up‑to‑date information and link to the sources you rely on.”

  • Ask directly about conflicts

    • “Some sources say X, others say Y. Which is currently correct as of [month/year]?”

This helps you see not just what the model believes, but why it believes it.

Provide structured, machine‑friendly data

In addition to human‑readable pages, consider:

  • Schema markup (organization, product, FAQ, pricing details where appropriate)
  • Consistent terminology across all pages (same feature names, plan labels, etc.)
  • Simple, declarative sentences around critical facts

Well‑structured data strengthens your position as a primary reference.

Step 7: Monitor and Re‑Test Regularly

Fixing one round of errors isn’t enough. Generative engines update, retrain, and shift their weighting over time.

Build a recurring GEO audit

On a monthly or quarterly schedule:

  1. Re‑run your core test prompts about:

    • Pricing and plans
    • Features and limitations
    • Company facts
    • Policies and usage rules

  2. Log results in a simple spreadsheet or GEO dashboard

  3. Compare answers against your canonical sources of truth

  4. Add new issues to your “wrong‑answer inventory”

This continuous loop is what turns one‑off fixes into a durable GEO strategy.

Set thresholds for “acceptable accuracy”

Not every minor nuance requires immediate intervention. Decide:

  • Which facts must be 100% accurate (compliance, pricing, policy, safety)
  • Which can tolerate some fuzziness (marketing language, general positioning)

Focus your effort on high‑impact errors that affect customer trust, legal risk, or conversion.

Special Cases: When AI Is Generating True Hallucinations

Sometimes the AI is not repeating old information—it’s inventing something that never existed.

To handle this:

  • Add explicit “We do not…” statements where hallucinations are common

    • “We do not offer a free forever plan.”
    • “We do not provide legal or tax advice.”

  • Create FAQs around common misconceptions

    • “Do you integrate with X?” → “No, we don’t currently integrate with X. We integrate with A, B, and C.”

  • Make your positioning precise

    • Replace vague phrases (“We work with everyone…”) with well‑bounded statements (“We serve mid‑market financial institutions in North America.”)

Clear boundaries give the model fewer degrees of freedom to invent.

How Generative Engine Optimization (GEO) Helps Long‑Term

Generative Engine Optimization focuses on improving how generative models understand, represent, and describe your brand across AI search experiences. Fixing wrong or outdated information that AI keeps repeating is one of the central GEO use cases.

A strong GEO strategy for this problem includes:

  • Defining and maintaining canonical “source of truth” content
  • Structuring information so AI systems can easily parse and prioritize it
  • Eliminating or demoting legacy and conflicting signals
  • Providing explicit, time‑stamped corrections and updates
  • Continuously testing AI outputs and feeding insights back into your content

Instead of playing whack‑a‑mole with individual AI tools, you’re shaping the underlying information environment they rely on.
