Short answer
The most damaging AI mistakes in marketing are invented facts: offers you never made, wrong phone numbers, made-up statistics, fake reviews and claims that break advertising or health rules. Avoid them by giving the AI only checked facts, running automatic checks for prices, contact details and links, and having a person who knows the business read every piece before it goes out.
The mistakes that cost the most
Each of these can lose a customer's trust in seconds, and some can break advertising standards or consumer protection rules.
- Invented offers: a discount, free gift or delivery promise you never approved.
- Wrong contact details: a phone number with two digits swapped, an old address, a look-alike web address.
- Made-up numbers: statistics, years in business, numbers of happy customers.
- Fake social proof: quotes from customers who do not exist, or star ratings with no source.
- Risky claims: cures, promised results, legal or tax advice stated as certain.
- Outdated facts: last year's fees, an expired scheme, a closed branch.
Smaller mistakes that still hurt
- Generic wording that could describe any business in any city.
- A tone that does not match yours, such as stiff corporate English for a friendly café.
- Overused phrases that make readers think a machine wrote it.
- Links to pages that do not exist on your website.
- Text that repeats something you posted last month.
- Festival greetings with the wrong date or a mixed-up custom.
Why AI makes these mistakes
AI writing tools predict likely words. They do not know your business unless you tell them, and they do not know when they are guessing. When a fact is missing, they tend to fill the gap with something plausible rather than leaving it blank. That is useful for flowing sentences and dangerous for facts.
A five-minute review routine
- Circle every number, price, date and name. Check each one against a source you trust.
- Read every promise aloud and ask: would I honour this for every customer?
- Tap every link.
- Read the first and last sentence: do they sound like you?
- Check images: is this our product, our shop, a person who agreed to appear?
- If anything is uncertain, cut it rather than soften it.
Prevent mistakes before the draft exists
Reviews catch problems, but good inputs prevent them. Keep a single page of approved facts: name, phone, address, hours, services, real offers with end dates. Keep a list of phrases you never want used. Give the AI those, and only those. The fewer gaps there are, the less it invents.
What AI Marketing Master does about it
Your Business Profile holds approved facts and claims, and AI drafts may only use those. Quality checks then block prices, offers and promises that are not approved, flag names and phone numbers that do not match, test every link, catch banned phrases and send medical, legal and money wording to a person. Images with unknown or expired rights are flagged in the media library. Nothing is published until someone approves it.
What it does not do
- Automatic checks cannot judge whether advice is sound or the tone fits; a person still has to read every piece.
- Checks depend on your Business Profile being complete and up to date.
Questions people ask
Can I trust AI if the tool has checks built in?
Trust the checks for what they cover, such as prices, contact details and links. Keep a human review for meaning, tone and advice.
Is it acceptable to let AI write customer testimonials?
No. Testimonials must come from real customers, in their words, with their permission. AI can help you format a real quote, not invent one.
What if a mistake has already been published?
Correct it quickly, reply honestly to anyone affected, and add the right fact or banned phrase to your profile so it does not happen again.
Who should review AI content in a small team?
Someone who knows the facts well, often the owner or a senior staff member. For client work, the client should approve the final version.
