Tripadvisor-branded hotels revenue includes hotel meta revenue, primarily click-based advertising revenue, and hotel B2B revenue, which includes primarily subscription-based advertising and hotel sponsored placements revenue. For the three and six months ended June 30, 2023, 62% and 66%, respectively, and for both of the three and six months ended June 30, 2022, 69% of Tripadvisor Core segment revenue was derived from Tripadvisor-branded hotels. Tripadvisor-branded hotels revenue decreased $14 million during the three months ended June 30, 2023, when compared to the same period in 2022, primarily driven by a decrease in Tripadvisor’s European hotel meta revenue related to lower seasonal demand and increased competitive environment in paid channels, leading to a decrease in paid volume clicks. This decrease was partially offset by improved hotel B2B revenue when compared to the second quarter of 2022.
Tripadvisor-branded hotels revenue increased $21 million during the six months ended June 30, 2023 when compared to the same period in 2022, primarily driven by improved hotel B2B revenue, and improved hotel meta revenue in the U.S. and the rest of the world geographic markets, primarily driven by strong consumer travel demand compared to the first half of 2022, which was negatively impacted by the COVID-19 Omicron variant during the first quarter of 2022. In addition, Tripadvisor saw continued strength in hotel meta monetization in the U.S., as CPC rates remained robust when compared to the same quarter of 2022, as consumer demand remained strong. These improvements were partially offset by a decrease in Tripadvisor’s European hotel meta revenue during the second quarter of 2023, as described above.
Tripadvisor-branded display and platform revenue increased $5 million and $9 million during the three and six months ended June 30, 2023, respectively, when compared to the same periods in 2022, primarily driven by an increase in marketing spend from advertisers, in correlation with strong consumer travel demand.
Tripadvisor experiences and dining revenue includes intercompany (intersegment) revenue consisting of affiliate marketing commissions earned primarily from experience bookings and, to a lesser extent, restaurant reservation bookings, on Tripadvisor-branded websites and mobile apps fulfilled by Viator and TheFork, respectively, which are eliminated on a consolidated basis, in addition to external revenue generated from Tripadvisor’s restaurant service offerings. Tripadvisor experiences and dining revenue increased $15 million and $27 million during the three and six months ended June 30, 2023, respectively, when compared to the same periods in 2022, primarily driven by strong consumer demand for experiences, conversion rate improvements and enhancements to Tripadvisor’s online user experience.
Other revenue includes rentals revenue, in addition to primarily click-based advertising and display-based advertising revenue from cruises, flights and cars offerings on Tripadvisor websites and mobile apps. Other revenue remained relatively flat for the three and six months ended June 30, 2023, compared to the same periods in the prior year.
Viator revenue increased $80 million and $139 million during the three and six months ended June 30, 2023, respectively, when compared to the same periods in 2022, primarily driven by strong consumer demand for experiences across all geographies. Viator is also benefitting from a larger macro trend, or secular shift, as the large global market in which it operates continues to grow and migrate online from traditional offline sources.
TheFork segment revenue increased $6 million and $15 million during the three and six months ended June 30, 2023, respectively, when compared to the same periods in 2022, driven by increased consumer demand for dining, including increased bookings, during 2023 compared to the first half of 2022, as well as, a decrease in the negative impact of the COVID-19 Omicron variant which occurred during the first quarter of 2022.
Operating expense. Operating expense increased $27 million and $47 million for the three and six months ended June 30, 2023, respectively, when compared to the same periods in 2022, primarily due to increases of $17 million and $30 million, respectively, in technology and content costs due to increased personnel and overhead costs resulting from additional headcount and contingent staff to support business growth related to the travel demand recovery that began during 2022, as well as increases of $10 million and $17 million, respectively, in cost of revenue, the majority of which was due to increased direct costs from credit card payment processing fees and other revenue-related transaction costs in the Viator segment in direct correlation with an increase in revenue, as Viator serves as the merchant of record for the significant majority of its experience booking transactions.
Selling, general and administrative. Selling, general and administrative expense increased $71 million and $158 million for the three and six months ended June 30, 2023, respectively, when compared to the same periods in the prior year. The most significant driver of selling, general and administrative expense is selling and marketing costs, which consist of direct selling and marketing costs and indirect costs, such as personnel and overhead.
