what is the difference between the cotent network and the search network and the partner search network? what type of audiences play in each one and which venue is ost profitible
Depends on niche and competition... Free stuff offers convert very well on content, but sales are great on search. Test and track for everything and you'll find the best way for your products
you cannot say that one is more profitable than another bacon is right you need to test its the only way to validate it. I am in a special niche and some of my campaigns perform better on the content network and some campaigns i have completely turned it off. Just keep testing. hope this helps!
Here is everything you need to know about the different networks within google https://adwords.google.com/support/bin/topic.py?topic=25&hl=en_US All venues are most profitable if you play the game right. I suggest reading the google bible before getting your feet wet https://adwords.google.com/support/?hl=en_US then come back and ask questions
I use both. I like content network because I can get an image ad up in some niches for 1-5 cents a click. But if your visitors come via search they are more likely to click or buy
