Editor's note: this post is an excerpt from The Large Marketplace Comparison Guide which you can read now.
Online Travel Agents (OTAs) act as online marketplaces where tour and activity suppliers from all over the world can list their services. OTAs then spend a lot of time and money aggregating services from all over the world and marketing their inventory to a global customer base.
These marketplaces are large, huge in fact. They are established online and partner with top players in the industry, getting your products in front of a broader audience. This can be difficult for companies who want to stand out from the competition, as to get on the "Recommended" list can be tough. On the other hand, large marketplaces are susceptible to more regional competition as well as more curated, niche marketplaces.
