Review count, average rating and review recency are three of the most powerful ranking signals in Google's local search algorithm. A business with 150 reviews averaging 4.8 stars, with 20 new reviews in the last 30 days, will almost always outrank a competitor with 30 old reviews averaging 4.5. For tourism businesses in Hoi An and Da Nang — spas, hotels, restaurants, cooking classes, tours — building a genuine review system is one of the highest-return activities available.
Why fake reviews are never worth the risk
Google's spam detection has become sophisticated enough to catch most patterns of fake review activity — unusual velocity, reviews from accounts with no history, reviews that arrive in suspicious clusters. When caught, reviews are removed, and repeat violations can lead to listing suspension. Beyond the risk, fake reviews do not build the kind of trust that genuine reviews do — experienced international travellers notice when reviews read as inauthentic. The only sustainable approach is genuine reviews from real guests.
The post-service review request: the most effective system
The single most effective method for building review volume is a consistent post-service review request at the moment of maximum guest satisfaction. For a spa, this is immediately after the treatment when the guest is relaxed and happy. For a restaurant, it is at the end of a positive meal when the bill arrives. For a hotel, it is at checkout after a smooth stay. The system has three components: a trigger (the right moment), a tool (a QR code or short link), and a message (brief and warm, not pushy).
Building your review request QR code
- Go to your Google Business Profile and find your Review Link under 'Get more reviews'.
- Shorten the link with a URL shortener or generate a QR code from the direct link.
- Print the QR code and add it to your receipt, table card, room card or checkout desk.
- Add a short message: 'Enjoyed your visit? Share your experience on Google — it only takes a minute.'
- Test the QR code from different phones and ensure it opens directly to the review form.
Staff training: the human element
A QR code alone is less effective than a QR code accompanied by a brief verbal mention from a staff member. Training staff to say something simple — 'We'd really appreciate your Google review if you have a moment' — at the right time increases conversion significantly. The key is timing (during a clearly positive moment) and tone (warm and genuine, not transactional).
WhatsApp and Zalo follow-up
For tourism businesses that collect guest contact details — a hotel that takes a phone number at check-in, a spa that messages guests their booking confirmation — a follow-up WhatsApp or Zalo message the day after the visit is a highly effective review request channel. The message should be short: thank the guest for their visit, mention that reviews help the business and provide a direct link. Response rates are typically higher than email for tourism businesses in Vietnam.
Responding to every review
Responding to reviews — especially new ones — signals to both Google and potential guests that the business is actively managed. Positive responses can be brief and personalised. Negative responses require more care: acknowledge the issue, avoid being defensive and invite the guest to follow up directly. For a detailed guide on handling negative reviews, see how to respond to negative Google reviews for tourism businesses.
Review velocity: consistency beats bursts
Google's algorithm rewards steady, consistent review velocity over time. A business that receives 10 reviews per month every month outranks one that received 50 reviews in January and none since. This means the review request process needs to become part of daily operations — not a one-off campaign. Even 3–5 genuine reviews per month, sustained over a year, creates a review profile that is very difficult for competitors to match.

FAQ
Can I ask guests to change or remove a negative review?
You can politely invite a guest to update their review if you have addressed their concern — but you cannot pressure or incentivise them to do so. Google's policies prohibit offering rewards in exchange for changing reviews.
Should I put a review request on my menu or room card?
Yes — a QR code on a physical card that guests have in their hands at the right moment is highly effective. Keep the message simple: a thank-you and a direct request to share their experience.
Does the language of a review affect my ranking?
Google uses reviews in all languages for ranking purposes. English reviews tend to be most useful for international guests reading them, but Korean, Japanese, French or any language review counts equally for your local search ranking.
What is the minimum review count needed to rank well in the Hoi An local pack?
This varies by category and location. For competitive niches like 'spa Hoi An', businesses in the local pack typically have 50–200+ reviews. For less competitive categories, 20–30 genuine recent reviews may be sufficient to rank strongly.
