AI-written review replies: what sounds fake, and how to avoid it

AI, yes; robotic replies, no

Should you let AI reply to your reviews? BrightLocal, which runs the benchmark survey on customer reviews every year, recommends it: templates or AI suggestions save time, provided each reply is tailored so it sounds genuine¹. The same survey points out the risk: generic or templated replies put off half of consumers¹.

So the problem isn't AI, it's the reply that is recognisably automatic. Here is what gives it away.

The six signs of an automatic reply

1. It could answer any review

"Thank you for your feedback, your satisfaction is our priority." Nothing in the sentence shows the review was read. The fix: pick up a specific element, such as the dish, the timing or the name of the person who welcomed the customer.

2. It repeats the review instead of answering it

"We are delighted that you found our service quick and our staff welcoming." Picking up a detail, yes; handing the customer's own words back to them, adjective by adjective, no. React to what they say: "On Saturdays, we open a second till so the wait stays short."

3. It makes things up

This is the most serious flaw of language models: adding a detail that isn't in the review. Thanking a customer for "that delicious dessert" when they didn't have one is spotted immediately, and casts doubt on all your other replies.

4. It always starts the same way

Twenty replies opening with "Thank you so much for…": the reader of your profile notices it while scrolling. Vary the opening: the detail itself, an apology, an observation.

5. It talks like a customer service desk

"Don't hesitate to contact us", "we remain at your disposal", "your opinion matters to us": these are call-centre phrases, not the words of a neighbourhood business.

6. It is too long, or stuffed with keywords

Google recommends short, simple replies². As for keywords slipped in for SEO, they are useless: in the Whitespark 2026 survey, keywords in owner responses rank 182nd out of 187 local ranking factors³. We explain this in our article on local SEO.

Staying in control

Even well tuned, AI needs guardrails. Three are enough:

• Review critical reviews before publication: they are the ones that commit your business.
• Give instructions: your tone, your signature, what must never be promised.
• Sign on behalf of a person or the team: Google advises adding a name or initials, which makes the reply more authentic².

How ReplyTop avoids the robot effect

Every ReplyTop reply starts from a detail of the review and relies only on what it says. Customer-service phrases are banned, the reply fits in three sentences, and it is compared with the establishment's last hundred replies: if it reuses an opening already used or copies a sentence, it is rewritten. Your tone and signature instructions apply to every reply (from the Starter plan), and 1- and 2-star reviews wait for your approval.
