What these numbers actually mean
ROAS tells you how much revenue you generate for every dollar of ad spend. ROI goes further by accounting for costs and margin so you see profit, not just top line. CPA/CAC show what it costs to acquire a lead or customer. Together, these metrics help owners decide when to scale, fix, or pause a campaign.
How to set realistic assumptions
- CPC or CPM: pull historicals from your ad account or use industry ranges; adjust for your city and niche.
- CTR: creative, audience fit, and placement matter. If you’re below 1%, audit creative and audience match.
- Conversion Rate: ensure landing pages match the ad promise, load fast, and work on mobile.
- Lead/Sale Value: for lead-gen, estimate the revenue per closed customer × close rate. For e-com, use AOV and gross margin.
Small improvements compound
A 10% drop in CPC, a 15% lift in CTR, and a 10% lift in conversion rate can slash CPA/CAC dramatically. Test one variable at a time so you know what moved the needle.
Quick win checklist
- Match ad promise to headline above the fold.
- Use social proof near the CTA (reviews, ratings, badges).
- Reduce form fields for lead-gen; offer calendar booking.
- For e-com, clarify shipping/returns and show final price early.
- Add a follow-up sequence: email/SMS/retargeting after click.
Use AI to plan tests (without sounding robotic)
The built-in AI Campaign Advisor suggests experiments for audiences, creatives, and landing pages, and prioritizes actions that reduce CPA/CAC. Keep the language human and specific; the AI gives you a starting point you can tweak to match your brand.
Break-even and when to scale
Track profit per day and days to break even. When the campaign is profitable for 7–14 days and you’re not saturating the audience, scale gradually (e.g., +10–20% budgets) and protect your CPA/CAC with bid caps or tCPA.
