I'm actually surprised that the flower peddler budgets were that low. This just reinforces my long-stated belief that local flower shops can and should butt heads with these giants in THEIR LOCAL MARKETS and take those local markets away from them.
The numbers by themselves might be impressive to some. But when spread over a per capita or per square mile basis of the area they cover, they aren't so impressive. Local florists should get over being impressed and start figuring out that they can and should successfullly butt heads against these guys in their local markets and take their local markets away from them. It's affordable and can be done in many markets for much less than a lot of florists are paying these guys every month for the privilege of helping them (the big guys) compete against themselves and all local florists by filling for them.
The problem I see it is that along with their big budgets probably comes a significant adscore, which in turns grants them a much better ppc click rate than the average joe could command.
IMO, if a florist is going to go down the ws free road, rather than putting this ws service money into ppc as you suggested, I believe it might be wiser to put this same money into developing brand recognition.
But even better than adwords is some good old organic seo.
Lots more people click in the natural listings.
