There could be a number of reasons for a 10% booking decline. One possibility is that there is a problem with the user experience on the booking page. For example, the page may be confusing or difficult to navigate, causing users to abandon the booking process. Another possibility is that there is a technical issue that is preventing users from completing their bookings. This could be something as simple as a bug on the website or app, or something more complex like an issue with the payment processing system. Another potential reason for a booking decline is that there is an issue with the pricing or availability of the product or service being offered. If the price is too high or the product is not available at the desired time or location, users may be more likely to abandon the booking process. Additionally, if there are better or more appealing options available from competitors, users may be choosing to book with those competitors instead. Finally, it is possible that there is a problem with the marketing or promotion of the product or service. If users are not aware of the product or service, or do not understand its value proposition, they may be less likely to book. In this case, it may be necessary to revisit the marketing strategy and ensure that the product or service is being effectively promoted to the target audience.
