Google Ads Book button expands to Search and Performance Max

Google is putting the Book button on Search and Performance Max ads. Search Engine Roundtable reported on 28 August 2026 that the button, which runs through the Reserve with Google partner integration, is expanding from Local Services Ads and Maps ads onto two of the biggest paid surfaces in Google Ads. A searcher who clicks it leaves the ad and lands on the advertiser's own scheduling platform to book an appointment.

There is no Google blog post behind this. The change was spotted by Michel van Luijtelaar, who posted about it on LinkedIn, and written up by Search Engine Roundtable. That shapes everything below. What follows is a spotted change plus a practitioner reading of it, not an announcement with product documentation attached, and the honest version of this story is about an audit rather than a feature.

What Search Engine Roundtable reported on 28 August 2026

The report from Search Engine Roundtable on 28 August 2026 says Google is expanding the Book button through the Reserve with Google partner integration to Google Ads Search and Performance Max campaigns, where it was previously available on Local Services Ads and on Maps ads. The mechanic is the same one local businesses already know from the organic side: the button takes the click out of Google and into the scheduling tool the business has connected, and the appointment is made there.

Search Engine Roundtable also notes that Google appears to be doing this without advertisers asking for it, and that it will appear automatically for eligible merchants. An opt-out exists, though the author wrote that he was not sure how to reach it and pointed at Google help documentation instead of a path. The same report mentions that Google expanded its Local Services Ads booking partners earlier in that week, and raises the possibility, without confirming it, that the two moves are connected. It also says, hedged, that this had been seen in testing before.

The practitioner post on LinkedIn summarised the shift in one line: Reserve with Google has moved from organic Local Search and Maps onto paid surfaces. If you run Search or Performance Max and have already published an appointment action link, that link can now power a Book button on your ads. Nothing to build, and Google tracks the booking without extra tagging.

How an appointment action link becomes a Book button

The piece of plumbing at the centre of the 28 August 2026 report is the appointment action link. This is the booking destination a business publishes so that Google can route a searcher to it, and it is the same object whether the click arrives from an organic Maps listing or, now, from a paid ad. Nobody builds anything new for the ad version. The link that was already sitting on a location record is what the Book button on the ad uses.

That is the whole reason this story is a governance problem before it is a features problem. A new ad format normally arrives with a setup step, and a setup step is a moment when somebody in the account looks at what is being published. Here there is no setup step. Whatever link was published, by whoever published it, on whatever date, is the thing that now appears behind a paid button. If a business has one location and one booking system, that is a non-event. If a business has fifty locations, the ad surface has just inherited fifty decisions that were made by people who were not thinking about paid media at the time.

Why the link is usually owned by somebody else

Appointment action links are usually published as part of local listing work, not as part of paid search work. They are maintained alongside opening hours, categories, service areas and photos, which is why they tend to belong to whoever runs the local SEO and listings programme. The Book button on an ad crosses that ownership line. The asset stays where it was, but the consequence of the asset moves into the media budget.

Why a stale action link is more expensive than it was

The practitioner post on LinkedIn cited by Search Engine Roundtable made this point directly, and it is the sharpest thing in the story. Multi-location portfolios often carry hundreds of booking links, published at different times by different people. A link that points at a generic homepage instead of a real booking flow used to cost the business organic clicks. It now sits behind a paid Book button, and Performance Max will push budget toward it.

Work through what that means in an account. A Book button is a high-intent affordance. A person who clicks it has decided to book, not to browse, so the click is worth more and will be priced accordingly by an auction full of other advertisers who also want booking intent. If the destination is a homepage with no scheduling flow on it, the money is spent on the most expensive kind of click and then the intent evaporates on arrival. Worse, an automated campaign type reads engagement signals and allocates toward the surfaces that produce them, so a booking button that gets clicks and no bookings can absorb budget for a while before the pattern is obvious in reporting.

None of this requires anything unusual to go wrong. It only requires a link that was correct in 2024 and is now pointing at a booking system the business stopped using, a location page that was consolidated, or a homepage that somebody entered as a placeholder because the real scheduling URL was not ready that afternoon. Those links do not announce themselves. Nothing in an ordinary Google Ads report tells you that a booking destination is wrong, because as far as the platform is concerned the click was delivered successfully.

Eligible is not active, and why that matters in reporting

The distinction the practitioner post drew, reported by Search Engine Roundtable on 28 August 2026, is worth reading twice. Available is not the same as active. The "Appointments booked" goal reaches eligible accounts with no opt-in from the advertiser, but it only influences bidding once the conversion action is added to the campaign settings.

Two separate things are therefore happening at once, and they arrive on different schedules. The measurement piece can be present in an account without anyone having asked for it. The bidding piece only starts when a person deliberately adds that conversion action to a campaign. So an account can be sitting in a state where bookings are being counted somewhere in the interface while the bid strategy is entirely ignorant of them, and it can be sitting in the opposite state a week later because somebody tidied up the conversion goals without realising what they were switching on.

For anyone reading Performance Max reporting, that is the trap. Performance Max already makes attribution hard to unpick because the channel mix inside it is not fully exposed. Adding a conversion action that appeared without a decision, and that may or may not be feeding the bid strategy depending on a setting nobody remembers changing, makes a before-and-after comparison unreliable. If conversions in a Performance Max campaign step up and nobody on the team changed the creative, the audience signals or the budget, the first thing to check is whether the conversion action inventory changed underneath the campaign. This is ordinary hygiene for anyone running search and Performance Max campaigns, and it becomes load-bearing when goals can appear without an opt-in.

Healthcare is carved out, which matters for Bangkok

Search Engine Roundtable's 28 August 2026 report is explicit on one exclusion: healthcare is out. Google Ads does not allow booking links or goals for healthcare campaigns, so clinics keep the organic Book button only. The organic Maps and Local Search behaviour is unchanged; the paid version does not extend to them.

Bangkok has an unusually large concentration of advertisers who will read that sentence and need to work out which side of the line they sit on. Dental clinics, dermatology and aesthetic clinics, wellness centres, fertility clinics, hospitals running international patient acquisition, physiotherapy practices and medical tourism packagers all run appointment-driven paid search here, and all of them already deal with policy restrictions that other verticals never see. The source does not define where the healthcare boundary is drawn for this specific carve-out, and it is not this article's place to guess. What the report supports is narrower and still useful: if a campaign is classified as healthcare in Google Ads, the booking link and the booking goal are not available to it, and the Book button that a clinic sees on its Maps listing stays organic.

The practical consequence for a clinic marketer is that the audit below still applies to the organic side. A clinic that cannot get the paid Book button still has an appointment action link published on its listing, that link still receives organic clicks, and it can still be pointing at the wrong place. The exclusion removes the new budget risk. It does not remove the reason to check the link.

The opt-out sits in Google Ads, not the Business Profile

One structural detail from the 28 August 2026 report deserves its own paragraph because of who it affects. The opt-out sits in Google Ads, not in the Business Profile. That makes it an advertiser decision, and a local team cannot toggle it without Google Ads access.

In a franchise or a branch network, the people who maintain the listing are frequently not the people who hold the ads account. A branch manager who decides the booking system is being replaced next month can change the listing, but cannot switch off a paid button that is drawing on it. That gap is normally handled by a process rather than by a permission, and the process only exists if somebody writes it down. It is the same coordination problem that shows up whenever a listing asset starts driving lead generation spend, and the fix is a named owner rather than a clever setting.

What the source did not say

This is a short report about a spotted change, and being clear about its edges is more useful than filling them in. The table below separates what the 28 August 2026 report states from what it leaves open.

The audit, and how to run it

The advice attached to the 28 August 2026 report was to audit the action link for every location you or the businesses you manage operate this week. That is a task, not a strategy, and it is worth being concrete about what the task involves.

Pull the list before you judge it

Start with an inventory of every location record and the appointment action link published on it, with the date it was published and the person or team who published it if that is recoverable. A portfolio that cannot produce this list in an afternoon has already found its first finding. The inventory is the deliverable; the judgement comes after.

Open every link and watch where it lands

Check three things per link. Does it resolve at all, or does it redirect somewhere unexpected. Does it land on a booking flow for that specific location, or on a homepage, a general contact page, or a booking page for a branch that closed. Does the flow work on a phone, since the Book button is overwhelmingly a mobile affordance and a scheduling tool that renders badly on a small screen will lose the booking after the click has been paid for.

Then look at the conversion actions, not just the links

Separately from the links, check the conversion action inventory in each Google Ads account and note whether an appointments goal is present and whether it has been added to any campaign's settings. Write down the state before you change anything, because the value of this check is in noticing a change later, and you cannot notice a change from a baseline you never recorded.

What this means for Thai marketers

Start with the honest caveat. Search Engine Roundtable's 28 August 2026 report gives no country list, and nothing in it confirms that the Book button expansion has reached Thailand, on Search or on Performance Max. Anyone telling a Thai client that this is live here is going beyond the source. The correct posture is to check your own accounts and your own listings rather than to act on an assumption.

What is worth doing regardless is the underlying audit, because the cost of a bad appointment action link does not depend on this feature at all. Thai multi-location advertisers with appointment-driven businesses, salons, clinics that fall outside the healthcare restriction, service centres, showrooms and repair networks, tend to have listings that were built out over several years by branch staff, an agency, or both in turn. Booking links in that environment drift. Some point at LINE, some at a booking platform the business no longer pays for, some at the homepage. Checking them is cheap and the check has value today whether or not the paid Book button ever appears on a Thai account.

The second Thailand-specific point is about ownership. Thai branch networks often keep listing maintenance close to the branch, because the branch knows its own hours, its own phone number and its own staff. The 28 August 2026 report says the opt-out for this sits in Google Ads. If the ads account is held centrally or by an agency, and the listing is maintained locally, then no single person currently holds both halves of this decision. Deciding who does, before there is an incident to argue about, is a fifteen minute conversation that saves a much longer one later.

Third, be careful with reporting claims. If an appointments goal shows up in a Thai account and conversions rise, that is not automatically evidence that a campaign improved. There is no public benchmark for what a booking conversion rate should be in any Thai vertical, and there will not be one, because the number depends on the scheduling tool, the service, the price point and the language of the flow. Derive your own from your own data: record the booking completion rate you have now, before any of this changes, and compare against that rather than against a number somebody quotes at a conference.

Frequently asked questions

Do I have to build anything to get the Book button on my ads?

No, according to the practitioner post on LinkedIn reported by Search Engine Roundtable on 28 August 2026: if you run Search or Performance Max and have already published an appointment action link, that link can power a Book button on your ads, with nothing to build and no extra tagging for Google to track the booking. The report frames this as appearing automatically for eligible merchants rather than as something an advertiser requests.

Can I turn it off?

An opt-out exists and it sits in Google Ads rather than in the Business Profile, but Search Engine Roundtable's 28 August 2026 report does not document the path to it, and the author wrote plainly that he was not sure how. The practical takeaway is the ownership point: because the control is in the ads account, a local or listings team cannot switch it off without Google Ads access.

Does this apply to clinics and hospitals?

No. The 28 August 2026 report states that Google Ads does not allow booking links or goals for healthcare campaigns, so clinics keep the organic Book button only and the paid version does not extend to them. The source does not spell out how the healthcare classification is drawn for this carve-out, so a clinic advertiser should confirm its own campaign classification rather than infer it.

Is this live in Thailand?

Not stated by the source. The 28 August 2026 report contains no country list and no confirmation of availability in Thailand, so the only reliable answer is the one you get by looking at your own accounts and listings.

Will the appointments goal change my bidding on its own?

Not on its own. The practitioner post reported on 28 August 2026 draws the distinction that the "Appointments booked" goal reaches eligible accounts with no opt-in but only influences bidding once you add the conversion action to your campaign settings, which is why the goal being present and the goal affecting spend are two separate states to check.

If you run appointment-driven campaigns across more than a handful of locations, the useful response to this report is the boring one: get the list of appointment action links, open them, and record what you find. If you want a second pair of eyes on that inventory or on how your booking goals are configured across accounts, our team works on exactly this kind of cleanup.
