Frequently asked questions
What is CPM?
Cost per mille: what 1,000 impressions of your ad cost. Ad spend ÷ impressions × 1,000.
How do I get CPC and CTR?
Add your clicks: the calculator also shows your cost per click (spend ÷ clicks) and your click-through rate (clicks ÷ impressions).
What is a good CTR?
It varies a lot by platform, audience and offer. Compare your own ads with each other rather than with a general average: a new creative is often the fastest way to lift it.
How do I improve these numbers?
Fresh creatives are one of the levers you fully control. Adsmithy makes new ads from your product photo, so you can test more of them.
Is what I type stored?
No. The maths runs in your browser: nothing you type is sent anywhere.
Is it really free?
Yes, free with no signup and no limit.
