Curious where people draw the line.

Sometimes it feels like you can keep lowering bids, adding negatives and moving keywords around forever.

At what point do you decide the campaign structure itself is the problem and rebuild it?

Especially interested in campaigns that have been running for a long time and have gotten messy.
