Viator vs Google Ads: Which costs tour operators less?

Every booking has a cost. With Viator, that cost is usually a commission. With Google Ads, it's the money you spend attracting customers to your own website.

The question is which costs you less — and which gives your business more value over time.

Viator gives you access to travellers browsing an established marketplace. Google Ads lets you reach people searching for experiences and send them directly to your website.

Neither is automatically better. The right choice depends on your commission rate, the cost of generating a direct booking, your profit margins and how much demand you can generate yourself.

Here's how to compare the two properly.

Viator vs Google Ads at a glance

1. What does Viator commission actually cost?

Viator allows tour operators to reach travellers who are already looking for things to do. You don't have to pay for each advertising click, and commission is generally charged when a booking is made.

That can make Viator particularly useful when you're starting out, have spare capacity or want to reach customers you might otherwise struggle to attract.

But commission comes directly out of your booking revenue.

Your actual rate depends on your supplier agreement and any optional programmes you use. Don't assume that every operator pays the same percentage.

Let's use an illustrative example. Imagine you sell a tour for £180 and your Viator commission rate is 25%.

You pay £45 in commission for that booking. If you receive 100 bookings at the same value and commission rate, that's £4,500 in commission.

That doesn't automatically mean Viator is poor value. Those bookings may have been difficult or expensive to generate through another channel. The important question is whether you could acquire comparable bookings more profitably elsewhere.

Where Viator works well

Viator can be a good fit if you:

• Are a new operator without an established source of direct bookings.
• Want access to travellers already browsing for experiences.
• Have available capacity and want to generate additional sales.
• Don't yet have a website or marketing setup that consistently converts visitors into customers.

Where the costs can add up

As booking volume grows, commission can become a significant expense.

You also have less control over the marketplace environment. Travellers can compare your experience with competing listings, and the customer relationship is managed within Viator's booking framework and terms.

You may receive the information needed to fulfil a booking, but that isn't the same as controlling the entire customer relationship or having unrestricted permission to market to that customer in the future.

For an established operator generating a high volume of bookings, it's worth calculating whether some of that demand could be acquired more cost-effectively through direct bookings. Our guide to OTA commission rates compares Viator with the other major platforms.

2. What does Google Ads cost per booking?

Google Ads works differently.

Instead of paying a commission on each booking, you pay to bring potential customers to your website. Some will book, some will enquire, and others will leave without taking action.

Your cost per booking depends on how much you pay for clicks and how effectively your website converts visitors into customers.

Consider the same £180 tour. Imagine you spend £600 on Google Ads and generate 20 completed bookings.

Your advertising cost is £30 per booking. In the earlier Viator example, commission was £45 per booking. On these illustrative figures, Google Ads costs £15 less per booking.

However, the £30 figure only covers advertising spend. You also need to account for any agency management fees, payment processing, booking software and other relevant costs.

And there is no guarantee that Google Ads will achieve this result. Actual performance depends on your market, competition, website, pricing, availability and campaign management.

Where Google Ads works well

Google Ads may be attractive if you:

• Have a good website and a straightforward booking process.
• Sell experiences that people actively search for.
• Know which tours have healthy profit margins.
• Can measure completed bookings and their revenue.
• Want to build a stronger direct-booking channel over time.

Where Google Ads can go wrong

You pay for clicks whether or not they lead to bookings.

If your adverts attract the wrong searches, your landing page fails to convince visitors or your booking process is difficult to use, your budget can disappear without producing enough sales.

Campaigns also need ongoing management. You need to review search terms, exclude irrelevant traffic, improve your adverts and check that bookings are being measured correctly.

Google Ads gives you more control over how you acquire customers, but that control comes with responsibility and financial risk.

3. Calculate your break-even cost per booking

This is where the comparison becomes useful.

Rather than asking whether Viator or Google Ads is better in general, work out how much you can afford to spend acquiring a direct booking.

If your average Viator commission is £45 per booking, then £45 is your initial comparison point for a £180 booking.

But it's not necessarily your true break-even point. Direct bookings may have different payment processing costs, cancellation rates, customer values and operating costs. You may also pay an agency to manage your campaigns.

Use the calculator below to compare the basic acquisition costs.

The goal is to establish a realistic cost per direct booking, then compare it with the commission you're currently paying.

4. Why direct bookings can be worth more over time

The difference between Viator and Google Ads isn't only about the initial cost of acquiring a booking.

Direct bookings can give you greater control over the customer journey, your brand presentation and opportunities to build an ongoing relationship with customers.

For example, you can improve your website, explain what makes your experience different, offer relevant additional services and make it easier for customers to book with you again.

Where you have the appropriate permissions, you may also be able to use customer information for future marketing.

These opportunities can add value beyond the first transaction. However, repeat bookings aren't guaranteed, and customer details must be handled in line with applicable privacy and marketing rules.

Google Ads can help you build a direct-booking channel, but it doesn't automatically create a profitable one. Your website, service quality, customer experience and marketing all matter.

5. Don't overlook Google Things to Do

Google also offers ways for travellers to discover tours and activities through its Things to Do experiences.

Depending on your setup and eligibility, your products may be able to appear through free booking links or paid advertising placements.

This can create another opportunity to reach travellers who are looking for activities, but free visibility isn't automatic. Availability depends on factors such as your booking platform, connectivity partner, product eligibility and integration (Google Actions Center).

If you're exploring ways to increase direct bookings, it's worth checking whether your booking system supports the relevant Google integrations.

The important point is that your options aren't limited to paying marketplace commission or running ordinary Google Search campaigns. The right combination depends on your business and the channels available to you.

6. When should you use Viator, Google Ads or both?

For many operators, this isn't an all-or-nothing decision.

Choose Viator when you need marketplace demand

If you're new, have limited marketing resources or need to fill available capacity, Viator can provide access to customers who are already browsing for experiences.

It can also help diversify your sources of bookings while you develop your own direct-booking channel.

Choose Google Ads when you can win direct bookings profitably

If your website converts well, you can measure completed bookings and your cost per booking sits comfortably below the commission you'd otherwise pay, Google Ads can help you grow a direct channel you control.

It tends to work best for experiences people actively search for, on tours where you know your margins.

Use both when each does a different job

Many established operators use Viator to reach marketplace demand and fill spare capacity, while using Google Ads to grow direct bookings on their best-selling tours.

The aim isn't to remove Viator. It's to avoid relying on any single channel, and to move bookings direct where the numbers show it's more profitable. If you do shift budget, do it gradually and keep measuring. Our guide to reducing OTA commission covers the practical steps.

7. Check your tracking before you compare

Viator gives you its numbers on a statement. Google Ads only reports what your conversion tracking captures, and missing conversion data can make your advertising look less profitable than it really is.

Many booking systems use redirects, iframes or third-party domains that can drop conversions on the way back to Google Ads. We explain why booking systems break conversion tracking in more detail. Before you trust your cost per booking, check that:

• A real test booking made through your website appears as a conversion in Google Ads.
• The conversion records the correct booking value and currency.
• Each booking is counted once, not twice.
• Your booking conversion is set as Primary, so campaigns optimise towards it.
• Google Ads bookings over a month broadly reconcile with your booking system, allowing for attribution differences.

If any of these checks fail, fix measurement before you make budget decisions. Our free booking-tracking self-assessment helps you work out whether your cost-per-booking figure can be trusted.

A sensible next step

Start with your own numbers: your commission rate from your supplier agreement and payout statements, your average booking value, and a cost per booking based on tracked conversions. Put them into the calculator above.

If direct bookings look cheaper, our tour operator marketing budget method shows how to fund advertising from the commission you'd save, and our Google Ads management for tour operators explains how we set campaigns up to be measured against booking cost.
