Abstract
We analyse the choice of pay-per-view (PPV) and pay-per-click (PPC) when a web publisher is a price taker in the market for advertising banners, and the number of visits is decreasing in advertising. Several pricing recommendations are developed. First, the web publisher should always choose either PPV or PPC. Specifically, if the click-through rate is less than the ratio of PPV to PPC prices, then PPV should be chosen, and vice versa. Furthermore, if the click-through rate is exogenous, then the optimal amount of advertising is the same for both pricing methods. Finally, if the click-through rate is endogenous, the amount of advertising will be different under PPV and PPC.

Notes
The number of clicks is related to the number of views through the click-through rate, that is, the rate of views that turn into clicks.
For a more extensive discussion of the web publisher market, see Mangani (2004).
They use the term ‘pay-per-view’ about subscribers' payment for content such as video on demand (as opposed to advertising sponsored access to web content).
The demand function adheres to the regularity assumptions set forth by Talluri and van Ryzin (2005).
Like Mangani (2004), we do not explicitly include this indirect effect in (1), as doing so would reduce tractability without altering our conclusions.
The click-through rate is sometimes also thought to be related to position on the website. A position high up (or near the result from a query) is assumed to have a higher click-through rate than a position lower on the screen (eg Edelman et al., 2007). We do not consider that dimension.
The objective function could also have been written as R(A N , A C )=c1N(A)A N +c2w(A)N(A)A C where A=A N +A C , and solved explicitly for amount of advertising sold as PPV, A N , and amount sold as PPC, A C . However, our form follows previous literature where A N =αA and A C =(1−α)A that more clearly shows the detachment between price regime and consumer behaviour in response to total advertising, A.
The respective second-order conditions are

.
Another sufficient condition to exclude a price regime would be that it is intercepted at its maximum by the revenue function of the other price regime that has nonzero slope. That is, that (3c) holds at the optimal output (6) of the inferior price regime, and at that advertising level, the preferred price regime has nonzero slope.
Here, we assume that revenue functions are strictly concave under pure PPV and pure PPC, respectively.
According to Shy (2008, p xi), ‘the most efficient way of learning about customers is by trial and error’. If the click-through rate is increasing (decreasing) in advertising, levels sufficiently above (below) the optimal advertising amount found for PPV must be searched.
