I basically want my banner ads to randomly appear on websites that fall within the category/keywords that I'm advertising in. Besides placement targeted ads, how would I do this?
use the content network More information can be found in the google help section about how to run content banner ad campaigns
Placement targeted ads are through the content network. I want to use banner ads only I don't want to choose which websites they appear on. I want them to appear randomly if that's possible.
Create only image ads for your adgroup, then put in your keywords, and turn search off. Your banner ads will run on sites/pages according to your keywords.
again, that is a keyword content campaign. Placement is different than content And your ad cannot be displayed randomly, it does need to follow a portfolio of keywords to help decide where to display on the content network. Random but targeted at this point. Again, read the google help section, it will explain it in detail
