I definitely set up two different campaigns for each, the Sponsored Search, and then a totally different campaign for the Content Network. I use Sponsored Search for all types of products and services. I use the Content Network exclusively for CPA type of offers. I have read that you don't want to combine the two in the same ad campaign. This is what works for me, and I watch my campaigns like a hawk lol. Good luck, Carmen
google content network is very big ( adsense) but yahoo content network is small, mainly there own site yahoo.com so focus on yahoo search.
Yahoo Search Marketing=>Put your business in front of potential customers at the precise moment they're searching for what you sell.
