Google Reviews, Local SEO and AI Answers: What Agencies Need to Know

Yes, Google reviews can affect local search rankings. Google's own help page says local results are mainly based on relevance, distance and prominence, and that prominence is partly based on how many reviews a business has. It says "More reviews and positive ratings can help your business's local ranking." Replying to reviews is also on Google's list of tips.

That's what Google says. This guide sticks closely to it, because local SEO is full of confident claims about exact ranking factors that nobody outside Google can prove. For agencies, being the person who knows the difference is worth a lot.

Do Google reviews affect local search rankings?

Google's Business Profile help has a page called "Tips to improve your local ranking on Google". It's the closest thing to an official statement, so it's worth reading in full. On how ranking works, it says:

"Local results are mainly based on relevance, distance and prominence. Together, these factors help Google find the best match for customers' searches."

Reviews come in under prominence:

"Prominence means how well-known a business is. Prominent places are more likely to show up in search results. This factor's also based on info like how many websites link to your business and how many reviews you have. More reviews and positive ratings can help your business's local ranking."

So the honest answer for a client is: yes, reviews are one of the things Google looks at, alongside many others. You'll see articles that put a percentage on how much reviews matter. Google doesn't publish anything like that. In its own words: "We do our best to keep the search algorithm details confidential to make the ranking system as fair as possible for everyone."

And one more line from the same page that's worth putting in every proposal: "There's no way to request or pay for a better local ranking on Google."

What does Google say about reviews and local ranking?

Pulling it together from Google's local ranking page and its review tips:

• The number of reviews is part of prominence.
• Positive ratings can help local ranking.
• Replying to reviews is listed as a tip. Google says replying "shows that you value their feedback" and that "Positive reviews and helpful replies can help your business stand out."
• Getting more reviews is encouraged, using a Google link or QR code, as long as it's done without incentives. Google's tips page says incentives for reviews are "strictly prohibited".

What Google doesn't say is that reviews outweigh everything else, or that any particular number of reviews unlocks a ranking. Be wary of anyone who claims to know.

The three factors, in plain English

Relevance

How well a Business Profile matches what someone searched for. Google says to "provide complete and detailed business info" so it can match the business to relevant searches. For your client, that means the right primary category, accurate services and a description that says what they actually do.

Distance

How far the business is from the person searching. Google says that if a customer doesn't share where they are, "Google uses what it knows about their location." You can't change distance, which is why a business rarely ranks across a whole city from one address. Set that expectation early, especially with multi-location clients.

Prominence

How well known the business is. Google mentions links to the business's website and reviews as part of this. It's the factor most influenced by what happens outside the profile: customers, press, local links and, yes, reviews.

How do you optimise a Google Business Profile?

Google's local ranking page lists the basics. They're simple, and they're where most profiles fall down.

1. Verify the business. Google says verification "tells Google that you're authorised to represent the business, so it's more likely to show up in search results." You also need to be verified to reply to reviews.
2. Keep information complete and accurate. Google says "Businesses with complete and accurate info are more likely to show up in local search results." That includes the full address (if customers visit), hours, special opening hours, the business category and attributes such as parking or Wi-Fi.
3. Respond to reviews. Covered above, and in more depth in our playbook for negative Google reviews.
4. Add photos and videos. Google suggests these to "show customers what you offer and tell the story of your business".
5. Add in-store products, for retail businesses in eligible countries.

For agencies, the trap is doing this once at setup and never again. Hours change at bank holidays, menus change, a location closes for a refit. Build a monthly check into your service.

A monthly profile check for each location

• Are the hours right, including any special hours coming up?
• Is the category still the best match?
• Are there new photos, and do they show the business as it is now?
• Have all new reviews been read, and the ones that need it answered?
• Are the website link and phone number correct?

Where reviews fit into the bigger picture

For a local business, reviews do two jobs at once. They're part of how Google judges prominence, and they're what a customer reads before deciding to visit. The second job matters even when ranking doesn't move.

That's why the way reviews are collected matters as much as how many there are. A steady flow of fair reviews from real customers, asked the same way, is what Google's policies allow and what customers trust. Shortcuts such as incentives or only asking happy customers can lead to reviews being removed. Google's Maps policy says incentivised reviews "are not allowed and will be removed from Maps" and that merchants may not "selectively solicit positive reviews". See how agencies get more Google reviews for clients for the full method.

How do local businesses show up in AI answers?

This is the question clients are starting to ask. Google Search now includes AI features such as AI Overviews and AI Mode. So what changes for a local business?

Google's Search Central guide on AI features is clear that much stays the same. It says "The best practices for SEO remain relevant for AI features in Google Search" and "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary."

It also says "You don't need to create new machine readable files, AI text files, or markup to appear in these features. There's also no special schema.org structured data that you need to add." If someone tries to sell your client a special "AI optimisation file", that line is worth showing them.

The guide does list fundamentals that still matter, and two are directly relevant to local businesses:

• "Making sure that important content is available in textual form." Opening hours, services and prices should be readable text on the website, not just in an image or a PDF menu.
• "Checking that your Merchant Center and Business Profile information is up-to-date." The Business Profile work above helps here too.

The guide also notes that for AI features, a page "must be indexed and eligible to be shown in Google Search with a snippet". In short, a well-run website and an accurate Business Profile are the foundation for both classic results and AI answers.

What this means in practice for local AEO

"AEO", or answer engine optimisation, is a useful label for making sure a business's information can be found and quoted when someone asks a question. For a local business, that mostly means:

• A website that clearly answers the questions customers ask: where you are, when you're open, what you offer, how to book, what it costs.
• An FAQ section written in plain language, with direct answers first.
• Business details that match exactly across the website and the Business Profile.
• A healthy stream of recent, real Google reviews and thoughtful replies.

We'd avoid promising clients that they'll "appear in AI answers". Google says inclusion isn't guaranteed. What you can promise is that you'll get the fundamentals right.

What should an agency's local SEO report include?

A useful monthly report connects the work to things the owner cares about. Here's a structure per location:

1. Business Profile health. Verified, hours correct, category checked, photos added this month.
2. Google reviews. New reviews this month, the month's average rating, and how many received a reply.
3. Themes from reviews. What customers praised and complained about, in a few words each.
4. Customer feedback responses. If you run a feedback form, how many responses came in and what the main complaints were.
5. Profile performance. Whatever Google Business Profile performance figures and website analytics you can report accurately for the month.
6. Work done. Replies written, profile edits, website changes.
7. Next month. One or two actions per location.

Keep ranking claims modest. If you report positions from a rank tracker, say what tool and what location you measured from, because distance changes local results so much.

For agencies offering reviews and feedback as a managed service, the report naturally covers both. Slot Flow syncs Google reviews into the same dashboard as customer feedback responses, so you can see each location's reviews and complaints together. Our guide to white-label reputation management covers what to put in a reputation report.

Common myths to steer clients away from

"You need X reviews to rank." Google publishes no such number.

"Reviews are the number one ranking factor." Google lists reviews as part of prominence, one of three main factors. It doesn't rank them against each other publicly.

"Keywords in reviews boost rankings, so ask customers to mention them." Google's policy says merchants shouldn't "request that specific content be included" in reviews. Don't do it.

"Paying for a Google product improves local ranking." Google says "There's no way to request or pay for a better local ranking on Google."

"You need special files or markup for AI search." Google's AI features guide says you don't.

Pulling it together for clients

The plain version you can give a business owner:

• Keep your Business Profile complete, accurate and verified.
• Ask every customer for an honest Google review, the same way, with no incentives.
• Reply to reviews thoughtfully, especially the bad ones.
• Make sure your website answers customer questions in plain text.
• Fix the problems your customers tell you about.

None of that is a trick. All of it comes from Google's own guidance. And it's work an agency can do well, month after month.
