Check what is already in place. The remaining checks point to the work you need before comparing performance. **How the recommendations work** No conversion definition or tracking test: analytics. No CRM feedback: CRM integration. No lead-quality agreement: lead generation. Unclear attribution: analytics. All checked: verify a sample of actual journeys. No agency is selected by this tool. Our target conversion is defined CRM outcomes return to marketing reports Sales and marketing agree on lead quality Forms and conversion events have been tested Attribution limits are recorded Start with a shared conversion definition and a test journey from the form to CRM. [Explore marketing analytics](https://globalleadindex.com/services/marketing-analytics/) ## A lead is not a sale Case analysis keeps each metric attached to its definition and context. **Enquiry** → **Qualified lead** → **Sale** Evidence review ## [Tensar: AI-related search clicks are not AI referrals](https://globalleadindex.com/cases/tensar-ai-keywords/) The useful distinction is the denominator: clicks for a selected keyword set are not a direct count of visits from an AI answer. Preserve the original label when comparing vendors. Evidence review ## [Omnicharge: meetings and deals use different time windows](https://globalleadindex.com/cases/omnicharge-meetings/) Do not divide the deal headline by the annual appointment count: the time windows differ. A conversion rate needs the same cohort followed through its sales cycle. ## Choose the work before the team Fourteen disciplines, with different deliverables and acceptance checks.

A shared name does not guarantee a shared rule.
