TripAdvisor announced on Tuesday that it has become the first travel site to feature 150 million reviews and opinions, which represents a 50 percent increase year-over-year. 

That means that TripAdvisor collects more than 90 user contributions per minute.

Each year, more than two billion unique worldwide visitors scan more than 3.7 million accommodations, restaurants and attractions on the massive site.

On top of that, more than 500 million people worldwide find TripAdvisor’s ratings on brand websites each month. TripAdvisor partners with nearly 1,000 brands, including Wyndham.

And, in case you were wondering, the 150 millionth post on TripAdvisor referenced Cameron House Inn in North Carolina. It read, “A warm and inviting retreat…you’ll want to return!”

Fittingly, it was the first review written by the member, demonstrating how TripAdvisor continues to attract new content.

"Fourteen years ago, TripAdvisor saw an opportunity to help travelers help each other make informed travel decisions by sharing their first-hand experiences, reviews, and photos," said Steve Kaufer, co-founder and CEO of TripAdvisor. "Now, the internet and user-generated content have completely changed the way we plan, book, and share our trips."

According to a study by PhoCusWright, more than 50 percent of travelers want to check out reviews of a destination before booking. More than 80 percent said reading reviews makes them feel more confident about their ultimate decision. And 80 percent read at least six to 12 reviews before making their decision.

So, you could see how being a top-rated hotel, restaurant or attraction on the site could be great for business.

Another fun fact: More than 24,700 TripAdvisor members have contributed at least 100 reviews. The average number of reviews for a hotel in the top 500 of most searched destinations is 174.
