FAQ

What does "Mille" in CPM mean?
"Mille" is Latin for thousand. So, CPM is literally "Cost Per Thousand" impressions.
Is a high CTR always good?
Mostly, yes. A high CTR indicates your ad is relevant. However, if those clicks don't convert into sales or leads on your website, you may be attracting the wrong audience or have issues with your landing page.
How do I lower my CPC?
You can lower CPC by improving your ad's Quality Score (on platforms like Google Ads), which involves increasing ad relevance, improving landing page experience, and achieving a higher expected CTR. Better audience targeting also helps.
Can I calculate one metric from the others?
Yes. The metrics are related. For example, `CPC = (CPM / 1000) / (CTR / 100)`. This shows that if you can increase your CTR while keeping CPM constant, your CPC will decrease.
