An AI brand accuracy audit checks whether an assistant describes your business in a way a customer can rely on. Start with verifiable facts, test a consistent set of questions, and investigate errors against the information available online. An incorrect answer may misinterpret accurate material or have no traceable source; do not assume every error originates on your website. Correcting your source material is a practical action; controlling every future AI answer is not.

A business can be mentioned frequently and still be misrepresented. The assistant might describe an old service, imply that a product is available in a country you do not serve, or present an expired offer as current. Those errors can attract the wrong enquiries and create promises your team must later undo.

Create a dated reference record

Before testing an assistant, agree on what the business actually says. Prepare a compact record of the trading name, official website, audience, products or services, locations served, pricing approach, and important exclusions. Assign an owner and a review date to each changeable fact.

Separate objectively checkable claims from judgements. Whether you sell a monthly subscription is a fact. Whether you are the best choice for an entrepreneur is an opinion that depends on criteria. Trying to correct every unfavourable comparison will distract the team from genuine inaccuracies.

For a fictional consultancy, a reference record might say: serves independent retailers in the Netherlands; offers fixed-scope marketing audits; does not manage advertising accounts; prices are quoted after scope review. Those statements make it possible to detect an answer that incorrectly advertises a monthly media-buying service.

Ask three kinds of question

Begin with identity questions: What does this company do? Where does it operate? Which website belongs to it? Include the official domain if the name is ambiguous, and label that run as domain-assisted rather than treating it as spontaneous discovery.

Next test purchase questions: Does the company offer a particular service? Who is it suitable for? Is there a public price? What happens after an enquiry? These questions expose claims that can affect a customer's decision.

Finally use comparison questions: How does this business compare with a named alternative for a specific need? Keep the need concrete. A useful response should explain relevant differences and uncertainty, not merely repeat a flattering description.

Create 12 prompts across these groups and run them on both platforms on two dates. Use fresh conversations, retain the wording, and record model or mode labels, language, location, and available search settings. That is 48 planned observations. It is an audit sample, not a census of what every potential customer sees.

Verify claims independently of the citation label

Open linked pages and compare the actual passage with the answer. ChatGPT's help guidance explicitly warns that search results and citations may be incomplete or incorrect. Gemini may also display related material rather than an explicit source for every sentence. A displayed link is a starting point for verification. [S2, S3]

Record both the assistant's claim and the supporting evidence. Use a short extract only where necessary, keep the URL, and note the source's date. Do not ask the same assistant to validate itself and treat its reassurance as an independent check.

Prioritise errors by their consequences

Fix a false product capability or service promise before a minor tone issue. Ask what a reasonable customer might do because of the claim and what happens if they act on it. An inaccurate eligibility statement can matter more than a missing slogan.

Use a simple triage record: the claim, customer consequence, source, responsible person, proposed correction, and next review date. Keep recurring themes together. Ten answers repeating the same outdated service description may point to one underlying source problem rather than ten separate writing tasks.

Improve the source material you can maintain

Check your home, about, service, pricing, and frequently asked question pages for conflicts. Put decisive information where a visitor expects it. Replace vague language with explicit statements of who the service is for, what is included, and when information was reviewed.

Preserve useful historical articles, but add a clear update where an old offer or product name could confuse readers. Review business profiles and partner listings you control. Where an external publisher has a factual error, use its correction process with evidence; do not manufacture reviews or endorsements to overwhelm the result.

In Webflow, review both the visible CMS copy and the fields used for summaries or search previews. A corrected paragraph can coexist with an outdated card summary. Keep the name, description, and destination consistent across the visitor journey.

Retest without claiming that the edit caused the change

Save a dated baseline, make a defined set of corrections, and repeat the original prompts. Note other changes that occurred during the observation period. An improved answer after an edit is encouraging, but it does not prove which source the system used or whether the improvement will persist.

Track confirmed accuracy among the factual claims you checked, alongside unresolved claims and the severity of remaining errors. Do not count an omitted fact as false, and do not inflate the score by excluding difficult responses.

Can a business force an assistant to use its preferred description?

No. It can make reliable information easier for customers and systems to find, correct inaccurate material it controls, and use available feedback channels. None of those steps guarantees a particular answer.

How often should this audit run?

Repeat it after a material product, pricing, positioning, or market change. For stable businesses, a smaller recurring sample may be sufficient. Choose a schedule based on how often your facts change and what an error could cost.

Start with one question that could lead a customer to the wrong purchase. Verify the answer and establish whether a source correction is needed. If it is, make the correction clear enough that a person can understand it immediately; otherwise record the unsupported output and use an appropriate feedback route.
