Frequently Asked Questions

What CPM is good?

Display $1–5, social $5–15, video $15–30+ — context dominates. Compare within channel and audience, never across. The tool ships 7 platform presets (TikTok $1.50, YouTube $3.50, Twitch $4.00, Twitter/X $5.00, Facebook $6.00, Instagram $8.00, LinkedIn $9.00) across 3 modes: CPM, RPM, and Estimate.

CPM vs CPC?

CPM buys views (branding), CPC buys clicks (performance). High-CTR creatives make CPC cheaper; broad reach favors CPM.

How do I lower CPM?

Broaden targeting, refresh creative (fatigue inflates costs), and test placements. Frequency above 3 usually wastes spend.

Do CPM figures upload?

No — math runs locally in your browser. Figures never leave your device.
