Tripadvisor is operating a fatiguing business model on outdated tech. The company is late to the game when it comes to capitalizing on their massive amounts of review and user preference data to build a better experience for travelers. As a result, site traffic and revenue have declined. Tripadvisor blames Google for its declining traffic, and while Google has certainly had an impact, the truth is, Tripadvisor has failed innovate and create a compelling reason for travelers to use the site. Instead of focusing on features that would add value for the traveler, the company has doubled down on building more advertising into the site. This isn't a strategy for growth. This is a strategy for milking ever cent out of a declining audience that will eventually slow to a trickle.
