So far the FB CPC hovers around $0.70. We need &gt;200 users per flight booking. A hotel booking has not been made through our platform yet. Not much data has been collected though, seeing as we&#x27;ve only been live for 2 weeks.<p>It might be important to note that, at this point, we&#x27;re not so much interested in how much we make from the actual booking as much as we&#x27;re interested in the conversion rate itself. We use the Expedia &amp; SkyScanner APIs, which was more practical from a technical perspective to get to MVP as soon as possible. But the affiliate fees for flights are close to nothing ($2 if we&#x27;re lucky) and we have different solutions in mind.<p>We only ask for the user to sign-up once she clicks the &#x27;save itinerary&#x27; button, which we believed would be the most seamless. The most confusing part of the product so far has been the fact that we currently have two &#x27;book now&#x27; buttons once the user tries to book her flight, something we&#x27;re addressing.
