I Stopped optimizing for sessions. Started optimizing for session quality. Here's what changed. Onboarded a new client last month. First thing I asked for was the previous agency's report. Everything was green. Sessions up. Traffic up. Cost per click down. Honestly looked like a well run account. Then I actually looked at what that traffic was doing. One channel was sending 60% of the sessions. It was responsible for 11% of the conversions. Another channel barely 8% of total volume was closing 34% of conversions.
