I'm currently using PPC to drive traffic to my landing pages. I have learned a lot over the last few months. The one thing that is still not clear is how much I should be spending on non-converting keywords.
I can use an A/B split test calculator on keywords that are getting sales, but determining when I should pause non-converting keywords is still a mystery to me.
Let's say I'm promoting a product that pays $20 per sale. Would 2x the payout be enough per non-converting keyword? Is this amount too much to test a keyword? Or should I be spending more?
