Cosmos has added around 300 hotel and destination maps and videos to its main website as well as to its accommodation arm, somewhere2stay.com.
The videos feature key hotels across the Mediterranean, as well as clips giving a taste of long-haul destinations.
Until now the operator has only featured videos for specialist product such as Lapland.
Cosmos commercial and product director Stuart Jackson said the video-linked properties were outselling accommodation without videos elsewhere but stressed they are the operator’s top-selling properties.
He added that the hotels with videos were being tagged in order to analyse online behaviour more closely.
The operator is also working on the websites to ensure videos and maps are easy to find.
Jackson said the plan was to highlight the properties with videos and maps within the availability search, as well as create a dedicated section listing which properties and destinations have videos.
