Google's Content Network?

[RichB]

When I'm doing my PPC campaign do I want my ad to be shown on Googles content network?

I don't see why not?

It really depends on your budget per day.
Content networks do get your ad out there more, but they also have a lower conversion ratio for the most part and can run up the budget. If you are lowballing it, then no, I'd opt out of the content network, but if you are wanting your ad on all eyes then you might get some great leads from the content network.
My best bet is : if the ad money is very limited is to opt out, then do a search for sites that you really want your ad on and do a site target on them.
