Convertels Ads
Convertels Ads
An advertising measurement and conversion infrastructure that connects hotel advertising to real booking and contact behaviour.
Convertels Ads measures meaningful conversion signals that occur on a hotel's website and booking journey, and sends them server-side to configured advertising platforms.
By providing conversion feedback to Google Ads and Meta, it enables advertising platforms to evaluate not only website visits but also the more meaningful user actions that take place along the booking journey.

Platforms
Supported advertising platforms
Google Ads
Convertels Ads can send eligible measured conversion signals server-side to configured conversion goals in Google Ads.
The Google integration uses Google OAuth 2.0 and the Google Data Manager API.
Meta
Convertels Ads can send eligible conversion signals server-side to a configured Meta dataset through the Meta Conversions API.
The goal is to provide advertising platforms with conversion signals that are more meaningful than simple browser-side pageview data.

- a successful booking,
- WhatsApp contact,
- phone contact
to be passed to the advertising platform as conversion signals.
