The “Kate effect” is in full force again. Usually the term refers to the immediate sell-out of one of her enviable pieces of clothing, but now we're talking about something a bit grander in scale. According to TripAdvisor, there has been a 25 percent increase in rental bookings in India since Prince William and Kate Middleton returned from their royal tour of the country.

The duo spent six days visiting hot spots in Mumbai, New Delhi, and Bhutan (all with an official photographer, so there are tons of photos to check out ). The pair's final day included posing for an iconic image outside the Taj Mahal, where Princess Diana was photographed decades earlier.

"Increasingly we've noticed that when high-profile public figures like the Royal Family are photographed in a destination, holidaymakers will actively search on TripAdvisor Vacation Rentals for properties in those locations,” Saskia Welman of TripAdvisor Vacation Rentals told IBTimes UK. “This developing trend is illustrated by the correlation between the high volume of media coverage resulting from the Duke and Duchess' trip to India and the recent surge in demand for the country on the site."

Along with the 25 percent increase in bookings in the country overall, the booking website also saw a 200 percent boost in searches for Mumbai, the royal couple's first stop.
