Keeping a high score in the search results is important, and one way to achieve this is by responding directly to all messages. However, it's important to note that you don't need to reply to every single message within a given request if you have already provided all the necessary information. Your response time is measured based on your initial response to a message, rather than subsequent responses.
By consistently responding to messages and requests, you improve your score and make it easier for Travellers to find your motorhome.
