What to Expect in the First 60 to 90 Days

Tracking ROI on Google Ads the Right Way
ROI measurement must go beyond surface metrics.
Track conversions: purchases, signups, calls.
Monitor micro-conversions: video views, button clicks, downloads. These reveal intent before final conversions.
Distinguish ROAS from ROI: ROAS measures revenue per dollar of ad spend, while ROI factors in costs such as fulfillment, labor, and software.
Calculate CPA, AOV, and LTV: cost per acquisition, average order value, and lifetime value define whether campaigns truly scale profitably.
As Search Engine Journal notes, the businesses that win with PPC are those that focus on lifetime value and downstream conversions rather than just click volume Search Engine Journal.
