I’m taking mostly about CPC, yes.
But you put all this long-term content marketing on sites that have massive traffic… which they have bexouse they are free. And they are free becouse they are financed by CPC ads. Would they be worth it behind the paywall reaching 1/1000th of the audience? Burst of the PPC bubble will take town a lot of placements with it.
Also, also I would be very cautious about studies proving the long-term efficiency of contend advertising, since those studies are inherently hard to design. Often.wjat you are measuring is basicly brand recognition, which grow over time by the virtue of running your business.
As for now there is somewhat meaningful body of evidence that advertising works well in early stagas. Your potential clients exist somewhere, and you need to inform them that you exists. Money well spent.
But once you cross that threshold… all sugest that Coca-Cola and oreo are loosing money on every dolar spent on advertising… we knew it before, and Digital Marketing was promosed to be the solution thanks to advenced tracking and analytic. It’s not. It’s just as ineffective, and it’s getting worse every year.
A similar case was with scans from “mobile scanners”. Since those are used on patients to sick to be transported, their cases were disproportionaly “malicious”. Model was effectively optimozed to detected if scaner was stationary or mobile.
