Short answer: Keep one source of truth for your business facts and push it everywhere: your website, Google Business Profile, directories, and data aggregators. AI assistants assemble your hours, phone number, services, and service area from scattered sources and trust whichever version has the most corroboration — so search what the AIs say about you and correct wrong facts at their source.
Picture the scene. A homeowner asks ChatGPT whether your company handles after-hours emergency calls, or what your Saturday hours are. The assistant answers confidently, and it is wrong. It quotes hours you changed last spring, a phone number you retired two years ago, or a service area you stopped covering. The homeowner never calls. You never find out you lost the job.
This is the accuracy problem, and it is getting sharper every month AI assistants take more of the "who should I hire" workload. An AI does not phone your office to verify. It assembles your business from facts scattered across your profile, your website, directories, aggregators, and reviews. When those sources disagree, it trusts whichever version has the most corroboration. The stale version usually wins that contest, because stale listings have had years to multiply while your correct update exists in exactly one place.
The fix is one source of truth, pushed consistently everywhere, plus a routine that hunts down the wrong facts AI systems repeat and corrects them at the source. This post is that routine. It sits next to three related jobs on this site, and it pays to know the boundaries: our NAP consistency guide keeps your name, address, and phone identical; our profile field-by-field rebuild gets the profile itself right; and our AEO and LLM optimization service handles the broader AI-visibility program. This post is the accuracy layer across all of them: making sure the facts about your business are correct everywhere AI systems look.
Every AI answer about your company is assembled from a short inventory of fields, pulled from your Google Business Profile, your website, directories, and reviews. Know the inventory and you know exactly what to keep accurate:
That is roughly the entire inventory of business facts AI assistants pull about your company. Every field that is wrong or inconsistent somewhere is a field the AI can get wrong in front of a homeowner.
AI systems do not have a fact-checking department. When two sources disagree about your hours, the system resolves the conflict by weight of corroboration: whichever version appears in more trusted places wins. That is the whole mechanism, and it explains why stale data is so durable. Your correct update exists on your profile; the wrong version exists on eight directories, two aggregators, and an archived review page.
The usual ways a contractor's facts go stale:
The pattern is always the same: the correction happened in one place and the stale copies kept circulating. Accuracy work is circulation work.
You cannot fix what you cannot see, so start by asking. Run these four questions about your own business on ChatGPT, Perplexity, and Gemini, and log exactly what each one says:
Flag every answer that is wrong, incomplete, or conflicts with what another assistant said. Then trace each wrong fact to its source: search the exact wrong fact in quotes and you will usually land on the directory or aggregator feeding it. That source is the thing to fix, not the AI. Rank what you find by business impact: wrong phone or hours is lost calls today; a wrong service list is lost jobs this week; a wrong address or a competitor's number attached to your name is a five-alarm fire.
Order matters. Fix at the source, not at the symptom, because you cannot edit an AI's memory. You can only change what it reads the next time it looks:
Then set expectations honestly. Profile edits surface within hours to a few days. Directory corrections take days to weeks. AI answers update on their next crawl and index cycle, and no assistant publishes a timeline for that. If a fact matters enough to cost you calls, the quarterly re-check below is how you confirm the correction landed.
Generic businesses get the generic twelve fields. Contractors have a few extra facts AI systems quote, and each one is worth getting exactly right:
Third-party mentions shape what AI systems "remember" about a brand, which is why off-site accuracy matters as much as on-site accuracy: the HubSpot analysis of answer-engine visibility makes the same point about off-site signals. Your facts live on other people's websites whether you manage them or not.
Accuracy decays the same way rankings do. Keep it cheap and routine:
Accuracy is the unglamorous half of AI search. Nobody pitches it on a webinar, and it will not make a case study. But every AI recommendation your competitors win starts from the same foundation: facts the system can trust.
They assemble your business from facts scattered across your profile, website, directories, and reviews. When those sources disagree, the system trusts whichever version has the most corroboration, which is often the stale one, since old listings have had years to multiply. The wrong answer is a data problem, not an AI problem.
Your Google Business Profile is the primary entity source for local facts like hours, categories, and service areas, because Google corroborates it against your website and directories. Your website is the primary source for service details and pricing. Everything else is corroboration, which is why consistency across all of them matters.
Profile edits usually surface within hours to a few days. Directory corrections take days to weeks depending on the platform. AI answers update on their next crawl and index cycle, and there is no fixed timeline, which is why you fix at the source and publish the corrected fact somewhere crawlable rather than waiting on the assistant.
Use one canonical number on your Google Business Profile, website, and every directory, and do tracking at the website level instead. A different number on each page splinters your entity data and teaches AI systems that your business has several identities. If you must use tracking numbers, keep the canonical number as the primary listing everywhere.
Quarterly, plus immediately after any change to hours, phone, services, or service areas. The quarterly pass is simple: ask the major AI assistants four basic questions about your business, log what they say, and trace every wrong fact to its source. A stale fact you ignore is a fact your competitors' clean data will beat.
Profile, Maps rankings, citations, reviews, competitors, plus whether AI assistants recommend you, and whether the facts they quote are right. A prioritized action plan, free, no pitch.
