Years into an ongoing tug-of-war over direct bookings, it’s fair to say that Online Travel Agencies (OTAs), like Priceline, Expedia and Hotels.com, still stir up a lot of angst within the hotel marketing community. OTAs, after all, charge a substantial commission on each booking — generally in the 20% range — which eats into a hotel’s profit margin.

The price of winning a direct booking is considerably less than an OTA, especially when cultivated through earned acquisition channels like SEO, content marketing or email. But in some cases, depending on your market, audience and hotel type, the difference is not quite as black and white.

Here are three cases when biting the OTA bullet might be worth your consideration:

Metasearch In A Competitive Urban Market

If your hotel is competing in a highly saturated hotel market where consumers tend to shop for the best price — let’s say New York — the costs of running a metasearch campaign can quickly get out of hand. Google can charge you up to 6% of your nightly rate simply for a click to your website, and that’s before even converting the booking. Over the course of a month — including successful clicks that do lead to bookings — it’s certainly not out of the question to pay a cost of sale somewhere in the 50%-60% range.

Hotels In A Low-Traffic Market

For all the criticism they face, OTAs do a great job of distributing your hotel to consumers who previously were unaware of your brand. This is especially important for hotels in less high-profile destinations, where most of the marketing battle involves distribution and visibility. Some forms of advertising can still be very effective for these types of hotels, especially retargeting (when the guest is already familiar with you), but the volume simply isn’t there to warrant heavy investment in pay-per-click. You might not pay much for the ad placements themselves, but given the lack of search traffic for those keywords, chances are you wouldn’t see much return on the money you spent anyway

Overpriced Display Ads

For hotels with deep enough pockets to compete for high-traffic placements, display ads can be worthwhile as an acquisition channel that generates direct bookings For smaller hotels, however, the cost of sale can be hard to swallow: Not only are you competing for prime advertising space with higher-converting retargeting ads (which results in low ROI), but the price can easily top the 20% collected by OTAs.

Take a small boutique hotel in West Hollywood, for instance. You’re in a supremely competitive hotel market where your competitors have vastly higher advertising budgets, and your average daily rate (ADR) is on par with average urban lifestyle hotels (i.e., somewhere in the $200-$300 per night range). Even with the limitations of OTAs, the need to fill rooms means you wouldn’t be crazy to supplement your display ad budget with equal or higher investment in OTAs.

OTA bookings are inefficient for many hotels, and my recommendation here is certainly not to consider them as your go-to marketing channel. Rather, it’s to consider them as a sensible alternative to other high-cost digital channels. Is the 20% commission ideal? Far from it, but it all comes down to cost of sale and how you can most efficiently fill rooms at your hotel. Even with a high ROI, some acquisition channels can have a higher cost of sale than an OTA. At that point, you have to make your decisions based on what’s most important for your brand.
