I'm running a lead gen campaign and we recently developed a second landing page that we're sending only to a retargeted website audience. The page is on a different URL than the primary campaign and is built in Instapage. Shortly after launch, I noticed insanely high CPMs ($40 and above) for the retargeting ad set that goes to the new URL. We've used these same ads before and directed them to the main URL and the CPM was never that high. The question is -- can the new URL and page be responsible for this very high CPM?
