Use CTR to judge whether impressions are generating attention and clicks.
Compare cost per click and cost per conversion to see whether traffic and outcomes stay efficient.
Review campaigns over the same date range before comparing results.
Look at campaign objective before deciding whether a CPM is good or bad.

Frequently Asked Questions
What is a good CPM for social media ads?
There is no universal good CPM. It depends on platform, audience, objective, seasonality, and creative quality.
Why can two campaigns have similar CPM but different results?
Because CPM measures reach cost, while clicks and conversions depend on engagement, targeting, and offer quality.
Should I compare CPM across platforms?
You can, but the comparison is more useful when audience type, placements, and objectives are similar.
Can a high CPM still be acceptable?
Yes. A high CPM may still work if the campaign reaches a valuable audience and converts efficiently.
Why include conversions in CPM examples?
Conversions help show whether inexpensive impressions are also producing useful outcomes.
