Real-World Comparison:
Why Low-Cost Clicks Often Cost Hotels More

When hoteliers compare marketing agencies today, they often hear the same promises: a data-driven approach, more direct bookings, and measurable ROI. What really sets offers apart is rarely the promise itself. It is what happens behind the scenes. A long-standing ADDITIVE client tested the offer of another hotel marketing agency while continuing to run ADDITIVE campaigns in parallel. The results are directly comparable: the same hotel, the same time period, reservations, and revenue as the primary goal – but different campaign logic. 

The competing agency’s promise: lower click prices, fast activation, and no agency fee in the first few months. The offer sounds appealing, and for good reason. Efficiency is a valid goal. The only question is what “efficient” actually means. When you measure efficiency by cost per click, some offers look attractive at first glance. When you measure it by cost per actual booking – and by the revenue that booking generates – the picture changes.

In this article, we take a closer look at the specific results of this comparison. The analysis of real campaign data shows where differences can arise and how they can affect annual revenue.

At First Glance:
Many Impressions, Low-Cost Clicks

In digital marketing, some metrics are easy to communicate and are often presented as success indicators in sales conversations: impressions, clicks, and cost per click. They feel tangible. But for hotels, the more important question is this: How many of those clicks ultimately lead to a reservation?

What This Shows:
Inquiries Are Not Automatically Bookings

In hotel marketing, clicks are a means to an end. What a hotel ultimately needs are inquiries – and more importantly, inquiries that turn into actual hotel reservations.

Inquiries can be an important intermediate step. But they do not automatically generate revenue. Every inquiry requires time and effort to process. It only creates business value when it turns into an actual reservation.

‍

This is where a decisive difference in campaign strategy becomes clear. The competing agency generated 346 inquiries at a low cost per inquiry. At first glance, that looks like a strong result. But only 25 of those inquiries became reservations – a conversion rate of 14:1. ADDITIVE generated 551 inquiries that resulted in 103 bookings – a conversion rate of 5:1. This directly affects the cost per reservation: €84.87 compared to €175.79.

The difference is rarely caused by individual ads or creative assets. What matters is the foundation behind them. Algorithms optimized for “inquiry submitted” learn exactly that: they generate many form submissions, regardless of whether there is real booking intent behind them. ADDITIVE trains systems for actual conversions: reservations and measurable revenue. That may result in higher costs per click, but it also leads to significantly higher quality for every individual inquiry.

Translating This Into Hard Numbers:
ROAS and Reservation Revenue Compared

ROAS, or return on ad spend, was used as the benchmark for measurable campaign performance. It directly compares the advertising budget invested with the revenue generated. This makes the efficiency of the ad spend visible as a percentage.

‍

The analyzed campaign data shows that differences in click prices or reach do not necessarily determine which approach is more commercially successful. The decisive factor was how effectively the generated demand could be converted into actual reservations and revenue.

A hypothetical scenario:
What would have happened if the €4,395 budget used by the competing agency had been invested in ADDITIVE campaigns instead? Based on the calculated average cost per reservation, around 52 additional bookings could have been generated. Multiplied by the average booking value, that would mean around €72,000 more revenue with the same budget – in three months, without additional investment.

This projection shows the commercial leverage that can emerge when hotel marketing is consistently managed based on bookings and revenue. As advertising costs continue to rise, these efficiency differences become increasingly important.

What Is Behind the Numbers:
Three Structural Differences

Three structural differences explain why the results are so far apart.

1. Campaign Goal: Inquiry or Booking?
Algorithms learn what they are optimized for. When a campaign is trained for “inquiry submitted,” it generates many inquiries – including from people who only have a question or do not intend to book. ADDITIVE explicitly aligns campaigns with actual reservations and revenue. That makes the learning phase more demanding, but the result is substantially better.

‍
2. Campaign Mix: One Campaign or the Full Journey?
In search engine marketing, the competing agency relied exclusively on Performance Max. This campaign type is quick to set up and automates many processes. However, it often provides limited transparency: which markets are being targeted, in which language, and on which platforms. Without a clean campaign setup, black boxes can quickly emerge. It then becomes difficult to understand which measures actually contribute to success.

ADDITIVE combines different campaign formats across multiple stages of the automated digital guest journey – from generating new demand to efficiently converting guests who are ready to book. The goal: reach travelers at every stage of their planning process, from initial inspiration to concrete booking intent.

3. Technical Foundation: Hospitality-Specific Marketing
The third difference is the most fundamental and, at the same time, the least visible. Many marketing systems promise data-driven strategies for more direct bookings. But they then evaluate and manage campaign success based on standard marketing KPIs such as clicks and impressions. What is missing is the connection to the hotel itself: occupancy, guest profiles, booking behavior, and seasonal patterns.

A strong technical foundation is not built on one single configuration. It is a system of many components working together.

• The starting point is specialization:
  ADDITIVE works exclusively in data-driven online marketing for hotels. This means every decision — from campaign structure to software development — is aligned with the specific requirements of the resort and leisure hotel industry.
• Official partnerships:
  As a Google Premier Partner, ADDITIVE has access to resources, insights, and support that standard agencies do not. ADDITIVE also maintains official partnerships with Meta, Bing, and other global advertising platforms.
• Proprietary software solutions for hotel marketing:
  ADDITIVE’s proprietary software solutions connect marketing data directly with real hotel data from the hotel PMS. They are aligned with individual goals such as booking quality, guest structure, occupancy, and actual revenue.

All of these factors create a professional infrastructure that ensures continuity and long-term results in the collaboration.

What Hotels Can Take Away

There are valid reasons to try new hotel marketing offers: lower entry costs, easier campaign activation, or the desire to test something different. That is not the problem. The problem is measuring campaigns only by metrics that are easy to evaluate and communicate, but say little about the hotel’s overall business success.

A low click price does not show whether the right people clicked. A high number of inquiries does not show how many of them become bookings. What matters is the path from the first click to the confirmed reservation — and how profitable that path ultimately is.

In hotel marketing, the central question is therefore not how inexpensive a click on an ad was. The real question is how much that click contributed to the hotel’s business success.
