Siri, Alexa and Google Don't Agree on the Best Plumber in Town. Here's Why.
It is 10:40 on a Sunday night in San Antonio, and water is coming through the ceiling of a hall bathroom. The homeowner does not open a laptop. She says it out loud, to whatever is closest.
Ask the same question three ways and you can get three names. The iPhone on the counter might suggest one plumber. The speaker in the kitchen might suggest a second. Her husband's Android phone, running Google's assistant, might suggest a third. Each voice sounds certain. Each one offers to dial.
None of them is lying, and none of them is broken. They are reading from different files.
Three assistants, three filing cabinets
A voice assistant does not drive around your city looking at plumbers. It looks things up in a database somebody else built, and each of the big three keeps its own.
Siri reads Apple Maps. When an iPhone answers a local question, the business facts come from Apple's map data. Owners manage that record through Apple Business Connect, a free dashboard most of them have never opened. Apple has long pulled ratings and reviews from partners, Yelp most visibly, and it now collects ratings of its own. Apple doesn't publish how Siri ranks one business over another, so anyone who quotes you the exact formula is guessing. Our guide to getting your business on Siri separates what is documented from what isn't.
Google's assistant reads Google Business Profile. Gemini and Google Assistant answer "near me" questions from the same data that powers Google Maps. Of the three files, this is the one most owners have touched, and the one with the most moving parts: categories, regular hours, holiday hours, service areas, reviews, photos, and edits that any stranger on the internet can suggest. The guide to Google Assistant and Gemini local search goes through it field by field.
Alexa reads licensed data. Amazon does not run a consumer map business the size of Apple's or Google's, so it leans on listing data it licenses from others. Yelp has long been a primary source for Alexa's local answers, and Bing fills in many web answers. Amazon doesn't publish the full list of suppliers, and it can change without notice. The practical point holds anyway: what Alexa says about your shop often starts with whatever Yelp believes. How Alexa finds local businesses traces that chain.
So the homeowner did not ask one question. She asked three companies to consult three records, each kept by a different staff, refreshed on a different schedule, and stocked with a different pile of reviews. Three answers is not a malfunction. It is the expected result.
Why the answers drift apart
Even a plumber who has claimed all three records can get named by one assistant and skipped by the next. Small differences add up. These are the usual suspects:
| What differs | How it changes the spoken answer |
|---|---|
| Hours | One record says open until 6. Another says 24 hours. At 10:40 p.m., "open now" decides who gets named. |
| Category | "Plumber" on one platform, "contractor" on another. An assistant matching the word "plumber" may pass over the second. |
| Location | A home-based business that hides its address on Google but shows an old storefront on Yelp sits at two different points on two different maps. |
| Reviews | Each platform counts its own. A plumber with 300 Google reviews and 4 on Yelp looks strong to one assistant and thin to another. |
| Name | "Mission Drain & Rooter" on Google, "Mission Drain and Rooter LLC" on Yelp. A person sees one company. A database may see two. |
| Freshness | The owner updates Google every month. Apple Maps still holds whatever a data supplier filled in years ago. |
Notice what is missing from that list: skill. None of the three files knows who fixes a slab leak best. They know who is open, who is close, whose category matches the words, and whose rating they trust. "Best" in a voice answer is an estimate built from those fields. When the fields disagree across platforms, so do the estimates.
There is a second reason, and you can't fix this one. The assistants are not trying to agree. Apple, Google and Amazon compete. Each wants its own answer to be the good one, built on its own data, and none of them checks the others' work. Nobody at Apple is calling Amazon to compare notes on Mission Drain & Rooter.
The voice search optimization package, examined
Into this gap walks the vendor.
You have probably seen the email. "Is your business voice-ready? Half of all searches are voice now!" Attached is a menu: Bronze, Silver, Platinum. Platinum promises "conversational keyword clusters," "AI-ready semantic content," "smart speaker indexing," and a monthly report with a microphone on the cover. It runs $499 a month, or $399 if you sign for a year, which they would love for you to do by Friday.
Here is what that package usually delivers. Someone pastes a block of text onto your homepage with sentences like "Who is the best plumber near me in San Antonio?" followed by your name, in a voice no human has ever used. Someone submits your business to forty directories nobody visits. Someone emails you a screenshot showing you rank first for a phrase nobody has ever said out loud.
Meanwhile your Apple Maps record still lists the hours from your first year in business, Yelp still has the cell number you dropped in 2022, and nobody on the vendor's team has logged into either one. Those two files are what Siri and Alexa actually read. The package polished the one thing the assistants weren't reading and ignored the two they were.
There is no smart speaker index to submit you to. There is no separate "voice ranking" floating above the listings. There is the record each assistant consults, and whether it is right. The fix page for when a voice assistant recommends your competitor walks through the real causes, and the list is shorter than the Platinum tier.
To be fair, not every agency selling voice work is running a racket. Some do the listing work properly. The test takes one question: which records will you log into, and what will you change in each one? If the answer is a slogan, keep your $499.
What a plumber should actually do
The goal is not to make Siri, Alexa and Google agree that you are the best. You can't, and nobody can sell you that. The goal is to make sure that when any of them considers you, the facts it reads are true, identical and complete, so the only things left to weigh are distance and reputation. Here is the work, in order.
1. Write the master record first
Before you touch any platform, write one plain document. Your exact public business name. One phone number. Your address, or your service area if customers never come to you. Hours for each day, holiday hours, and when you take emergency calls. A primary category and two or three secondary ones. A one-sentence description of what you do.
This document is the source of truth. Every platform gets copied from it, word for word. Most listing mismatches begin when three people filled in three platforms from memory in three different years.
2. Claim the files the assistants read
That means Google Business Profile, Apple Business Connect and Yelp for Business. Add Bing Places while you're at it, since Bing feeds Alexa's web answers and several AI chat tools. Each is free to claim. Each asks you to verify ownership, which can take a few days. Do all of them in the same week, from the master record, so they start out identical.
3. Fix the hours before anything else
For an emergency trade, hours matter more than any other field in a voice answer, because so many of these calls happen at night and on weekends. If you answer the phone around the clock, every record has to say 24 hours. If you don't, say exactly when you do. A Siri listing showing the wrong closing time is common enough that it has its own fix page.
4. Earn reviews in more than one place
Most plumbers ask every customer for a Google review and nothing else. That is sensible, since Google reviews drive the map pack. But Siri and Alexa may be weighing ratings from other places. Split the ask. Send some customers a Google link and some a Yelp link. Never pay for reviews, and never ask only the happy ones; every platform frowns on both.
5. Put plain answers on your website
The assistants also read the web, especially for questions beyond "who's near me," like "do plumbers charge more on weekends?" A service page that asks that question in a heading and answers it in two plain sentences is easy for a machine to lift and read aloud. Add LocalBusiness schema that matches the master record exactly. The voice search schema guide covers what is worth adding and what is mostly decoration.
6. Check the records on a schedule
Data drifts. Suppliers overwrite fields. Strangers suggest edits on Google, and some get accepted without the owner ever approving them. Put a reminder on the calendar each quarter to compare all four records against the master. It takes twenty minutes and it is the cheapest insurance in local marketing.
None of this is clever. The voice search guide for home services covers the details specific to the trades, like service-area businesses with no public address and the emergency phrases people actually say when the water heater lets go.
What agreement sounds like from the hallway
Go back to the wet ceiling. Suppose you have done the work. The homeowner asks her iPhone, and Siri reads an Apple record that says you're open 24 hours, 3.4 miles away, well rated. The kitchen speaker reads a Yelp record with the same hours and the same number. Google reads a profile that matches both.
You still may not be named every time. A plumber two miles closer, with more reviews, may win on one assistant or all three. But you are now in the running on every device in the house, and whenever an answer does say your name, it dials a number that rings your phone. That is the realistic goal: eligible everywhere, wrong nowhere.
Very few plumbers get there. Most have claimed Google and stopped, which is exactly why the gap is worth closing. It matters most for near me voice searches, because those are the questions that end with "Want me to call?" The full picture is in our guide to voice search for local businesses, and if you want the short version of why Google alone isn't enough, we covered it in the Google setting that decides whether Siri recommends you.
Frequently asked questions
Why does Siri recommend a different business than Google?
Because Siri reads Apple Maps data and Google's assistant reads Google Business Profile. They are separate records with separate hours, categories and reviews. If your details differ between them, or you have claimed one and not the other, the two assistants will weigh your business differently and may name someone else.
Can I pay Apple, Google or Amazon to be the spoken answer?
Not directly. Google sells ads that can appear on screens, but none of the three sells the spoken local answer itself. What you control is the accuracy and completeness of each record and the reviews on each platform. Be wary of anyone who guarantees you will be the voice answer.
Do I need a different listing for each assistant?
You need one listing on each platform the assistants draw from: Google Business Profile, Apple Business Connect, Yelp and Bing Places. All four should say exactly the same thing. You are not writing separate content for each assistant. You are copying one master record into four places and keeping it in sync.
How long before Siri or Alexa reflects a change?
None of the three publishes a firm timeline. Edits on Google often appear within days. Apple may review a change before it goes live. Alexa depends on when its data partners refresh their records. Make the change everywhere on the same day, check again after two weeks, and then recheck monthly.
Is voice search optimization different from local SEO?
Mostly it is local SEO done thoroughly, across more platforms than Google. The difference is the stakes. A mismatch that costs you a spot or two in a list of ten results can cost you everything in a spoken answer, because a voice assistant names one business. The work is listings, reviews and clear answers on your site.
Find out what each assistant is reading
You can't hear what Siri tells a stranger in Stone Oak at 10:40 on a Sunday night. You can check the records it reads. Our free Voice Search Visibility Check looks at your business across Google, Apple Maps, Yelp and your website, and shows you where the facts don't match. It takes a few minutes.
If the check turns up a mess, or you would rather not spend a Saturday logging into four dashboards, that is exactly what our voice and ambient assistant optimization service handles: one master record, every platform claimed and aligned, and a quarterly check so it stays that way. The next flooded hallway is coming. Make sure every assistant in the house has your number right when it does.
