But as online use of PDA's, cell phones, etc grow there could be a market for at least McDonalds on a PDA local search around lunch time. Recipe searches can bring up Mac n Cheese if someone searches for casserole or something. Lots of folks do lots of searches for recipes involving kraft products.
But for getting millions of people to eat at McDonald's or buy Kraft macaroni and cheese, PPC advertising isn't likely to be cost-effective unless the ad network is foolish enough to run unlimited numbers of minimal-CTR ads.
Varies greatly by industry. On one of my directory sites, at least, the vendors are the same (or in the same exact business) as I those am selling listings to for that category. I'd be hard pressed to tell you how much each adsense client spends for total clicks on my site but I do know that it costs each of the three paid listings in each category $200/year. Having a decent idea through my adsense stats and the stats from my site, I would say the ROI of my listing and being in the adsense box are roughly the same if were figured on an apples vs apples basis.
I'd venture to guess that the majority of advertisers don't get a good ROI from the content network anyhow.
