Hotel searches to San Antonio soared by 47% following Wednesday night’s episode of The Only Way Is Essex filmed on the island.
Searches to Ibiza as a whole increased by 19%, according to hotel comparison website trivago.co.uk.
The first episode of the reality show’s 13th season was shot on the Balearic island, including various venues around the party capital San Antonio.
When searches made on Wednesday were compared to searches made on the same day the previous week, travel interest to San Antonio increased by 47%.
Travel interest to Ibiza as a whole increased by 19% the same period.
Searches were for a hotel stay until the end of November.
A company spokeswoman said: “It is not uncommon for television programmes to spark an increase in travel interest, as the showcased destination is portrayed in a favourable light.
“Reality TV shows such as The Only Way is Essex typically focus on the best beaches, clubs, bars and restaurants, encouraging viewers to take this one step further and start searching for hotels online.
“After reality programme Made in Chelsea was filmed in New York City, travel interest to the city rose by 27%.
“Forty seven per cent per cent is a large increase but not surprising considering San Antonio’s reputation as a party resort, which is fitting for fans of The Only Way Is Essex.”
