I'd agree that we are cutting and pasting search queries into Google now, more than we were. I am at the Pharma SES in Princeton this week and when I want to find the site for the conference, I am literally copying the title of event into google to find the link each time - "3rd Pharmaceutical Search Engine Marketing Strategies Conference" and this is a 7 token search query.
How do you think SEMs should factor phrase, broad, and exact matches in their search campaigns to get the best coverage on these longer queries?
We're already seeing evidence of ad network "consolidation", as more networks are declaring themselves to be vertical networks, specializing in a particular genre of content. This is a way to get noticed in the crowded market and differentiate.
The companies with money will start buying ad networks, because they want to own that traffic and the advertising rights. And who wants to pay the middleman if they don't have to, right?
