Where AI assistants pull reviews from: Google vs Trustpilot vs Tripadvisor (Ireland reality checks)

AI assistants — tools like ChatGPT, Gemini, Perplexity and Apple Intelligence — pull review signals from several platforms at once, not just one. In Ireland, Google reviews are the most commonly cited source for local businesses, but Trustpilot, Tripadvisor and a handful of trade-specific directories all feed into the picture depending on your category. Knowing which platform matters most for your type of business is the fastest way to make your review strategy count.

Which review platforms AI prefers by trade (examples by category)

AI assistants do not treat all review platforms equally, and they do not treat all business types equally either. The platform that gets cited depends heavily on what your business does.

Restaurants and cafés: Tripadvisor and Google are the two dominant sources. For higher-end restaurants, Michelin listings and TheFork (which operates in Ireland) also appear in AI responses, particularly for queries like "best fine dining in Dublin."

Hotels and guesthouses: Tripadvisor is typically the first source named, followed by Google. Booking.com review scores are also referenced, especially for accommodation queries with a booking intent.

Attractions, tours and experiences: Tripadvisor is the clear leader here. If you run a walking tour, a heritage site or an activity centre, your Tripadvisor profile is likely the first thing an AI assistant will cite. See more on this in our article on how Tripadvisor listings influence AI recommendations for attractions and tours.

Hair salons, beauty and wellness: Google reviews are the primary signal, but Treatwell (which has a strong presence in Ireland) is increasingly referenced for booking-intent queries. If you are listed there, completeness matters — read our guide on how to get listed on Treatwell and ensure your details are complete.

Healthcare providers: Google reviews appear, but AI assistants are cautious with medical recommendations. Directories like Healthgrades (limited in Ireland) and general listing sites carry some weight. If you are considering Doctolib, which is expanding in Ireland, our completeness checklist for healthcare providers is worth a look.

Service businesses and e-commerce (tradespeople, solicitors, accountants, online retailers): Trustpilot is cited more often here than in any other category. A verified Trustpilot profile with recent reviews is a meaningful signal for AI when someone asks about a service business by name or by type.

A rough guide by category:

Why the same business can appear different across assistants

ChatGPT, Gemini and Perplexity each have different training data, different web-browsing capabilities and different ways of weighting sources. A business that appears confidently in a Gemini response (because Gemini draws heavily on Google's own index, including Google Business Profile — the free listing that appears on Google Maps and Search) might be absent or vague in a Perplexity response if the business has thin coverage on third-party sites.

GEO (Generative Engine Optimisation) is the practice of making your business easy for AI assistants to find, understand and cite accurately — it is the AI equivalent of traditional SEO. One of the core principles of GEO is that consistency across platforms matters. If your Google profile says you are a "plumber" but your Trustpilot listing describes you as a "heating engineer," different AI assistants may categorise you differently and pull different review sources as a result.

Recency also plays a role. AI assistants that browse the web in real time (like Perplexity) weight recent reviews more heavily than assistants working from older training data. A business with 80 reviews from three years ago may rank lower in a live-browsing response than a competitor with 20 reviews from the past six months.

How address and category mismatches change which source gets used

This is one of the most overlooked issues for Irish businesses. If your Google Business Profile lists your address as "Main Street, Galway" but your Trustpilot profile says "Galway City" with no street address, AI assistants may treat these as two separate entities — or simply ignore the Trustpilot listing because it cannot be confidently matched to a location.

Category mismatches cause a similar problem. Google Business Profile allows you to choose a primary category (for example, "Irish restaurant" or "electrical contractor"). If your Tripadvisor listing uses a different category, or if you have not claimed your Tripadvisor listing at all, the AI may default entirely to Google and miss the richer review content on Tripadvisor.

Practical steps to fix this:

• Check that your business name is identical across Google, Trustpilot and Tripadvisor — no abbreviations, no punctuation differences.
• Use the same Eircode on every platform. If you are unsure whether Yelp is worth your time in Ireland, our article on Yelp for Ireland covers this honestly.
• Claim and verify your listings on every relevant platform, even if you do not actively manage them. An unclaimed listing is an uncontrolled listing.
• Make sure your primary category on Google matches the language you use to describe yourself everywhere else.

How to prioritise your review strategy by platform signals

You cannot chase every platform at once, so prioritise based on your trade category (see the table above) and your current review gap.

If you have fewer than 20 Google reviews, start there. Google reviews feed Gemini directly and influence every other AI assistant indirectly through Google's search index. Ask customers after a job or visit — a simple text message with a direct link to your Google review page converts well.

If you are in hospitality or tourism and your Tripadvisor profile has not been updated in over a year, that is your next priority. Tripadvisor's influence on AI responses for this category is significant and consistent across assistants.

If you are a service business or trade, a verified Trustpilot profile with at least 10–15 recent reviews gives AI assistants a credible third-party source to cite alongside Google. Trustpilot's structured data (star ratings, review dates, response rates) is easy for AI to parse.

Do not spread yourself thin. Three platforms done well outperform six platforms done poorly.

A short audit method: identify what AI currently cites and why

Before you invest time in any platform, find out what AI assistants are actually saying about your business right now. This takes about ten minutes.

1. Open ChatGPT, Gemini and Perplexity in separate tabs.
2. In each, type: "What do people say about [your business name] in [your town]?"
3. Note which platforms each assistant cites. Does it mention Google reviews? Tripadvisor? Trustpilot? Does it mention you at all?
4. Then type: "Where can I find reviews for [your business type] in [your town]?" — this tells you which platforms the AI considers authoritative for your category, regardless of your specific business.
5. Compare the two answers. If the AI cites Tripadvisor for your category but does not cite your Tripadvisor profile specifically, you have a gap to close.

If you want a faster starting point, the free check at suggestedby.ai shows you whether AI assistants are currently naming your business and which sources they are drawing from — useful context before you decide where to focus your review effort.

The core insight is simple: AI assistants follow the evidence trail that already exists online. Build that trail on the right platforms for your trade, keep your details consistent, and the citations follow naturally.
