Bazaarvoice collects reviews from over 50 countries for travel listings in 38 languages. Reviews provide insights into topics discussed and can be used to personalize and segment messaging. Analysis found that ages 35-44 and 55-64 contribute the most reviews, ages 65+ give the highest ratings, and frequent travelers have lower ratings and are more critical. Engaging with reviews can increase key metrics like time on site, return visits, conversion rates and revenue.
