Separating campaigns for content and search network.

Does it worth do it with the current changes?

I rememeber doing separate campaings was a common advise here in webmasterworld.
Now, that rules are more clear and I'm setting up campaings for a new website, I see that I get identical bid prices in both search and content network.
I mean, before, I used to put lower bids to the content network and higher to the search network. Since there was no active/inactive, the ads eventually ran, even in very lower positions.
But now, if I put a lower bid on the content, the keywords go to inactive immediatly.
Any comments on how is the better practice these days?

The majority of people aren't bidding at the min CPC as it doesn't give them the necessary position, they're bidding much higher for it.

For these advertisers, using the old system of min bids for content and ROI/action based bidding for search is still working to separate out the networks.

If you're only min bidding, then the Google and content network will cross over as to which keywords are shown in these campaigns if you try to separate them out.
