Performance Max for Hotels: Where It Helps and Where It Burns Budget

What Performance Max actually is

Performance Max is a goal-based Google Ads campaign that runs across every Google surface at once: Search, YouTube, Display, Gmail, Discover and Maps. You give it a budget, a conversion goal, some assets and audience hints, and the algorithm decides who sees which format where. You do not pick keywords or placements. That is the trade: more reach and less control.

For a hotel this means one campaign can show a search ad to someone typing 'boutique hotel York', a YouTube clip to someone watching travel content, and a Maps promotion to someone browsing nearby stays. It is genuinely good at finding demand you would not reach with a tidy list of keywords.

The catch is that the same machinery that finds new guests will, if you let it, also chase the cheapest conversions it can find. For most hotels the cheapest conversions are people already searching your name, which is exactly the traffic you least want to pay a premium for.

Where Performance Max genuinely helps a hotel

Performance Max earns its keep when the job is finding new guests across formats you would otherwise manage as separate campaigns. It is at its best for upper-funnel reach, for filling soft periods, and for promoting a specific offer to people who do not yet know your property. Think of it as demand discovery, not demand capture.

In each of those cases you are asking PMax to do what it is built for: find incremental demand. The work is making sure 'incremental' is true, which is where the controls in the next sections come in.

• ›Reaching travellers earlier in the journey, before they have settled on a destination or a hotel, across YouTube and Discover.
• ›Pushing a time-sensitive offer (a shoulder-season package, a new spa suite) to broad but relevant audiences quickly.
• ›Squeezing value from remarketing inventory and lookalikes without building and managing each placement by hand.
• ›Covering long-tail, low-volume searches that never accumulate enough data to justify their own search campaign.

Where it wastes budget

Performance Max wastes hotel budget when it is allowed to harvest demand you already own. The two classic leaks are brand search and metasearch. Because branded clicks convert cheaply, an unconstrained PMax campaign gravitates straight to them, reports a glittering return, and bills you for guests who were already heading to your booking page.

The first leak is brand. Someone searches your hotel by name. PMax serves them a search ad, they click, they book, and the campaign claims the booking. But that guest typed your name; a good share of them would have reached you through your free organic listing or a cheap dedicated brand campaign. You have paid a premium for a booking that was nearly yours already.

The second leak is metasearch overlap. Google Hotel Ads, the booking module that sits beside the map, is where a lot of direct-versus-OTA battles are decided. If PMax is also bidding into hotel and local inventory, the two can compete against each other, push up your own costs, and muddy which channel actually drove the booking.

The third, quieter leak is reporting. PMax gives you very little visibility into where spend went. Without the right exclusions you can run it for months convinced it is your best performer, when in truth it is recycling demand your brand search and metasearch were already capturing more cheaply.

The one rule: never run PMax instead of brand search and Hotel Ads

The single most important decision is structural. Performance Max should sit alongside a dedicated brand search campaign and Google Hotel Ads, never replace them. If you switch off brand search and let PMax absorb branded traffic, you lose control of your most valuable, cheapest, highest-intent clicks and hand their pricing to an algorithm optimising for itself.

Run a tight brand search campaign so you keep manual control of bids and messaging on your own name. Run Google Hotel Ads so the booking module shows your direct rate against the OTAs. Then add Performance Max for the demand those two cannot reach. Brand bidding is usually the highest-return campaign a hotel runs, and the logic behind it is worth reading in full in the hotel PPC guide.

With that structure in place, every other control below exists to keep PMax in its lane: finding new guests, not poaching the ones your other campaigns already serve.

Brand exclusions: the control that matters most

Brand exclusions tell Performance Max not to serve ads against searches containing your hotel name. For hotels this is the difference between a campaign that finds new demand and one that quietly cannibalises your brand. Apply a brand exclusion list and your dedicated brand search campaign keeps that traffic, where you actually control it.

Google now offers a brand exclusions setting at the campaign level and account-level brand lists. Add your hotel name and its common misspellings and variants. This stops PMax competing with your own brand campaign and stops it claiming credit for bookings that branded search was always going to win.

Treat it as the default, not the exception. Unless you have a specific, measured reason to let PMax touch branded queries, exclude them. It is the first thing we check on any hotel account running Performance Max, and one of the more common fixes we make in an account audit.

Audience signals: hints, not handcuffs

Audience signals are the data you feed Performance Max to point it at the right people faster. They are suggestions, not hard targeting; the algorithm uses them as a starting point and then explores beyond them. For a hotel, strong signals dramatically shorten the wasteful learning period where PMax spends money working out who your guest is.

Because signals are hints, do not assume PMax will stay inside them. That is another reason brand exclusions matter: even with a clean audience signal, an unconstrained campaign will still drift toward cheap branded clicks if you let it.

• ›Your own data first: past guests, newsletter subscribers, people who started a booking but did not finish. This is the most valuable signal you have.
• ›Custom segments built from search behaviour and competitor or destination interest, for example people researching your city or your type of stay.
• ›Relevant in-market and affinity audiences, such as luxury travel or spa and wellness, used to sharpen the starting point rather than define the limit.

Asset groups: structure by what you sell

Asset groups are how you organise creative inside a Performance Max campaign. Each group holds a set of headlines, descriptions, images and videos aimed at one theme. For a hotel, the sensible split is by what you actually sell: rooms, spa, weddings and events, dining, seasonal packages. Each group can then point to the most relevant landing page.

Resist the urge to dump every asset into one group. A spa-focused group should carry spa imagery, spa language and land on the spa page; a weddings group should do the same for weddings. This gives the algorithm cleaner themes to match against and gives the guest a page that matches the promise in the ad.

Feed it strong assets, especially video. PMax leans heavily on YouTube and Discover, and a hotel that supplies only a logo and a couple of stills is handing the algorithm weak material to work with. Real footage of the property, the rooms and the location tends to do far more work than stock.

Where the ad lands is as important as the ad itself. A fast, mobile-first booking page is part of the paid budget, not a separate project, which is why we treat the hotel website as part of any paid plan.

Account structure: keep the channels separable

A clean hotel account keeps Performance Max, brand search and Google Hotel Ads as distinct, readable campaigns so you can always tell which one drove a booking. The goal is separability. If you cannot see how PMax performs with brand traffic stripped out, you cannot judge whether it is finding new guests or recycling old ones.

Practically, that means brand search in its own campaign, non-brand search in another, Google Hotel Ads running the booking module, and Performance Max scoped with brand exclusions to everything else. Set clear conversion goals at the campaign level so PMax is optimising toward completed direct bookings, not soft actions like a page view or a phone-number click.

This separation is what lets you read the account honestly. It is the same principle that runs through our wider hotel marketing guide: plan the channels as one system, but keep them legible enough to manage.

How to stop it cannibalising brand and metasearch

Stopping cannibalisation is a short checklist, not a dark art. Exclude your brand, keep dedicated brand and Hotel Ads campaigns live, watch the overlap, and measure on incremental bookings rather than the campaign's own ROAS. Do those four things and Performance Max stays a demand-finding tool instead of a demand-stealing one.

Metasearch deserves its own attention here. Because Google Hotel Ads and PMax can both reach into hotel and local inventory, the cleanest setup keeps your metasearch bidding deliberate and lets PMax focus on the formats Hotel Ads cannot serve. We cover that direct-booking channel in depth in our Google Hotel Ads and metasearch guide.

• ›Apply brand exclusions so branded searches go to your dedicated brand campaign, not PMax.
• ›Keep brand search and Google Hotel Ads running as separate campaigns, so PMax is never the only thing capturing high-intent demand.
• ›Watch for rising spend in PMax alongside falling volume in brand search or Hotel Ads. That pattern usually means PMax is poaching, not adding.
• ›Compare a period with PMax running against one without it. If total direct bookings barely move while spend rises, it is cannibalising, not growing.

Measuring it honestly

Performance Max will report a flattering return, because it tends to absorb cheap, high-intent conversions and present them as its own wins. The honest measure for a hotel is the same one that applies to all paid search: incremental direct bookings, and cost per direct booking set against the OTA commission you avoided on the same stay.

Start from clean conversion tracking that counts completed direct bookings, ideally with revenue, rather than form fills or clicks. Then test for incrementality. Pause PMax for a defined window and watch whether total direct bookings actually fall, or whether brand search and Hotel Ads simply pick up the slack. If they pick it up, PMax was recycling demand.

When PMax is genuinely adding bookings, the maths is easy to defend. A direct booking that would otherwise have cost 15 to 25 percent in OTA commission is worth winning even at a modest ROAS headline. When it is merely re-badging demand your other campaigns already had, no headline ROAS makes it worth the money. Getting that distinction right is most of the job, and it is the kind of work behind real results: one multi-property hotel chain we worked with added around £125,000 in direct booking revenue across 90 days once its paid mix was structured to grow demand rather than recycle it.
