RentShout uses call tracking technology to help rental marketers capture phone leads by assigning a unique phone number to each rental ad displayed on the web page and in directories, allowing interested renters to be connected directly with property managers or contact persons in real-time. This approach enables lead conversion and provides valuable insights into the effectiveness of marketing efforts through analytics and metrics tracking. The company leverages Twilio's API for call tracking, which has been found to be easy to use and provides outstanding support, enabling developers to build effective call tracking solutions quickly and efficiently.
