Frequently Asked Questions

What is a good cost per impression?

A good CPI varies by industry and business model. For e-commerce, CPI below $0.005 is excellent. SaaS businesses may accept higher CPI ($0.01-$0.05) due to higher customer lifetime value. Always compare against your conversion rates and profit margins.

How does this differ from CPM?

CPI (Cost Per Impression) measures cost per single impression, while CPM (Cost Per Mille) measures cost per thousand impressions. CPM is simply CPI multiplied by 1,000. Both metrics help evaluate advertising efficiency but at different scales.

Should I focus on low CPI or high impressions?

Focus on the right balance for your business goals. Low CPI is good for brand awareness, but high-quality impressions that convert to sales are more valuable. Consider your conversion rates, customer lifetime value, and overall marketing objectives when evaluating performance.
