MAN i am frustrated...I finally had a break even campaign in lead impact that was shaping up nicely.
It was breaking even in a category that had a min bid of .025, I changed that today to a category with .015 min bid, and even though I am paying much less, randomly, the CR dropped by half...after only about 40 leads... (it's an e-mail submit).
Is it really possible that they are shaving me that quickly? I am going to test another network against it but I have to wait for the campaign to get approved for now.
no waaay......so I just set up a campaign in an auto-insurance category with no competition and a min bid of 0.03 but if i set it up under some random category i get bids at half that price on the same URL.s?!? sneaky bastards.......
um THANK YOU ;-)
Categories don't matter at all on LI. I usually pick Other--->Lifestyle for US traffic and my min bid is always .015.
Now here's the cooler trick 
When you're going int'l with some countries such as the UK or France, you can pick Government--->Elections and this will give you .015 min view instead of .017. This will save you a ton of money in the long run and I wish I knew this earlier! (it doesn't work with all countries)
Anyways, goodluck.
