Large brands seeking to make a significant impact will always seek high-profile placement.
Is that laziness? Not really. It is ego. Even if no one ever bought a Coke because they saw the neon sign in Times Square, it is still important enough to Coke’s brand and culture to demonstrate that they are big enough and strong enough to put that message in that spot. So, as long as there are new-model-car releases, brand-launches and opening-weekends, there will be a reason to pay tons of cash for the home page of Yahoo! Scarcity will exist for that, and it will keep prices high.
But the problem comes in if you say “well, Yahoo’s home page is gone, so there goes the campaign”. Online advertising is all about technology innovation and the twin turbines of targeting and optimization are will both increase the revenues for publishers as well as the effectiveness for advertisers.
The shortage? It’s just gonna lead to more technology innovation. Any network/serving technology/targeting system who can (really) do optimization is in a good place right now. They’re the ones who will benefit the most from a shortage.
The importance of any home page on any portal will decrease as more and more traffic is generated directly through searches and links. The problem remains that advertisers want to re-create TV; they want one-stop-shopping mass buys; they want upfront. But they shouldn’t want that because it only creates a scarcity that drives up prices. That’s why I say it’s laziness, because if they really did their homework and figured out that they can get better targeting, better reach, more efficiency, more effectiveness by engineering ad hoc networks tailored to their needs, they’d benefit greatly. But that takes work: not just the effort of putting together one flight but research and education and experimentation.
One agency and advertiser will figure this out and then the others will catch up for the same reason Gary cites: ego.
