Before comparing paid media proposals, agree on what a useful lead looks like and how you will verify it. A dashboard full of form submissions cannot tell you which inquiries sales accepted. Use this checklist to make measurement responsibilities, evidence, and launch decisions explicit.
1. Define the outcome before choosing channels
Write down the offer, audience, service area, and next step. Then define three separate outcomes: a successfully received inquiry, a qualified lead, and a customer. Agree with sales on the qualification rule and who owns it. A form submission is an initial signal; it is not proof of fit, revenue, or profit.
Google Analytics distinguishes generate_lead from qualify_lead and close_convert_lead in its recommended lead events. Use those distinctions in your measurement plan. Event names alone do not implement the sales process or establish that a lead is qualified.
2. Ask for evidence at each handoff
Copy the following acceptance checklist into your project brief. Assign a named owner and a review date to each item. These are proposed acceptance criteria, not claims about a particular campaign or a promise of results.
- Form receipt — website owner: a controlled test reaches the intended destination once. Invalid input and server errors show a useful error and do not trigger the successful-lead event.
- Event capture — analytics owner: inspect a successful test in a test environment or the appropriate debugging tools. Record the event name, trigger, destination, and duplicate-handling behavior. Keep names, email addresses, phone numbers, and message text out of the GA4 event payload.
- Lead quality — sales owner: a sample inquiry can be assigned, qualified or disqualified, and given a reason. Keep internal tests separate from customer inquiries so they do not inflate the commercial report.
- Campaign reporting — media owner: show the source of spend, received leads, qualified leads, and customers. Document reporting dates, attribution settings, and gaps instead of forcing different systems to agree.
- Recovery — implementation owner: identify who investigates missing events or failed imports, where errors are visible, and how a retry avoids counting the same outcome twice.
3. Separate platform attribution from sales records
Keep the CRM or sales record as the source for qualification and closed business. Review advertising-platform attribution alongside it. A platform conversion total and a sales total answer different questions; investigate differences in timing, definitions, and attribution before treating them as tracking errors.
For Google Ads, ask which supported connection returns downstream outcomes and how its diagnostics are checked. Google’s current enhanced conversions for leads guidance describes offline outcome measurement and Data Manager. Confirm the current integration requirements when scoping the work; do not assume an old API tutorial still applies. This is separate from putting personal information into general analytics event parameters.
4. Make the report useful for a budget decision
For the same campaign cohort, report spend, inquiries, qualified leads, and customers separately. Calculate cost per qualified lead as spend divided by qualified leads. If none are qualified, show that explicitly instead of a reassuring zero cost. State how long leads have had to progress through sales; a new cohort is not comparable with one that has had months to close.
Ask for a short explanation of what changed, what the evidence supports, and what will be tested next. A cheaper inquiry is useful only if its downstream quality and economics support your goal. Avoid making a scale decision from one good day or a handful of leads.
5. Choose the next step from the missing evidence
- If the form or successful-lead event is unreliable, resolve that handoff before using its count to judge a campaign.
- If inquiries arrive but qualification is missing, agree on the sales workflow and report before treating all inquiries as equally valuable.
- If measurement is usable but volume is low, define a bounded test and a review date. Record uncertainty rather than promising an outcome.
