How BAGAI uses these metrics
Do not optimise the top of the funnel in isolation.
A falling CPL can look positive while qualification and close rates are deteriorating. Put the stages beside one another before deciding which campaign, audience or landing page deserves more budget.
- Compare CPL with cost per SQL.
- Check lead-to-SQL and SQL-to-sale rates.
- Use CAC and revenue where the data is reliable.
- Segment by campaign, source, offer and landing page.
- Investigate changes in quality before scaling spend.
