We also generate hotel content as a means of engaging with travelers, which is distributed online including via social media and our online magazine. Mobile app marketing remains important given the high importance of that device type.
We market our services and directly acquire traffic for our websites by purchasing travel and hotel-related keywords from general search engines and through advertisements on other online marketing channels. These activities include advertisements through search engines, such as Baidu, Bing, Google and Yahoo! (commonly referred to as Search Engine Marketing, or SEM), and through display advertising campaigns on advertising networks, affiliate websites, social networking sites and email marketing (commonly referred to as Display, Email and Affiliate Advertising, or DEA).
Our advertiser relations team seeks to provide tailored advice to each of our existing and prospective online travel agencies, or OTAs, providers of alternative accommodation, hotel chains and independent hotel advertisers. We have dedicated sales teams that manage the process of onboarding advertisers, maintain ongoing relationships with advertisers, work with advertisers to help them optimize their outcomes from the trivago platform and provide guidance on additional tools and features that could further enhance advertisers’ experience. We aim to remain in close dialogue with OTAs and sophisticated hotel chains to better understand each advertiser’s specific needs and objectives in order to offer optimal solutions through our marketplace.

We design our algorithm to showcase the hotel room and other accommodation rate offers that we believe will be of most interest to our users, emphasizing those offers that are more likely to be clicked and ultimately booked on our advertisers' websites. We consider booking conversion, which we describe in more detail below, to be a key indicator of user satisfaction on our website. At the core of our ability to match our users’ searches with large numbers of hotel and other accommodation offers is our auction platform, which we call our marketplace. With our marketplace, we provide advertisers a competitive forum to access user traffic by facilitating a vast quantity of auctions on any particular day.
