I'm prospecting a client that works in the same niche that a old and inactive client. I'd like to ask you guys if I can expect to pay the same (or almost the same) price for clicks if I use the same kws from the old client, as they are in the same niche and have similar landing pages. Have you ever faced something like this? Is the total volume of visitors, price and clicks, can be equal, or each adwords account has a different behavior depending on its age, history, PR, etc?
