We were in a very similar situation. Our account relied heavily on Performance Max and automated search campaigns, and after a while CPA kept increasing with little insight into what was driving results. Bringing in experienced specialists helped because they audited the account, restructured campaigns, improved conversion tracking, and tested where automation made sense versus where more manual control delivered better performance. The algorithm is useful, but it still needs the right strategy and clean data. If you're considering Aimers, their
saas google ads service is worth reviewing. A healthy account can definitely be improved with the right approach.
