Microsoft Audience Network on Search campaigns: cheap clicks or expensive noise?

Microsoft Audience Network gets switched on because the CPC looks great in week one. The clicks are cheaper, but the placements are mostly display-style inventory and the intent is usually weaker than on the search results page. Say a B2B software vendor with a $300 CPA turns it on across the whole account. Clicks go up and cost per lead may even drop on paper, but the leads are often junk and the search terms report gets messy fast.

My view is to keep it off the main Search campaigns. If you want to test it, give it its own campaign with a tight budget and a CPA cap, and judge it on qualified conversions, not click volume. If the numbers hold after a few weeks, scale it. If not, it's just cheap traffic.

Agree on the separate campaign. I'd go one step further and optimize to the qualified stage instead of the form fill, because bidding learns from whatever you feed it. If you import the CRM's sales-accepted status as an offline conversion, the cheap junk stops looking like a win.

The offline import is the right move, but the lag matters. If sales takes two or three weeks to accept a lead, the bidding is learning from data that's already stale. On a small budget the network campaign might only produce a handful of qualified leads a month, which is often too few for the algorithm to learn from. I'd keep form fills as the goal with a CPA cap for the first stretch, then switch to the qualified stage once volume is there. How many qualified leads does that account actually get in a month?

The lag point holds. On Microsoft specifically, offline import matches on MSCLKID, not a generic click ID. If the form doesn't pass that value through a hidden field, the sales-accepted import matches nothing and the campaign looks like it never converts, so check the match rate before deciding the traffic is junk. For the volume problem, an earlier stage like a booked discovery call usually arrives faster than sales acceptance and still filters out the cheap form fills.
