Crosswalk
The same sales stage has a different name, and different rules, on each platform. Check the linked documentation before choosing a goal; platforms update these.
| Sales stage | Google Ads | Meta Ads | LinkedIn Ads |
|---|---|---|---|
| Lead (form submitted) | Submit lead form conversion action | Leads goal (Instant Forms) or website lead event | Lead Gen Form submission or website conversion |
| Marketing-qualified or sales-accepted | Qualified lead goal, via enhanced conversions for leads | Conversion leads with a CRM stage sent through the Conversions API | Qualified lead event sent through the Conversions API |
| Sales-qualified or opportunity | Qualified or converted lead goal (within the 63-day upload window) | A later CRM stage, if reached within 28 days | Qualified lead event, if data arrives within 30 days |
| Won deal | Converted lead goal; often too late for bidding | Usually too late for delivery; use for review | Usually too late for optimisation; use for review |
Zephra sends CRM lead stages to Google (through the Data Manager API), Meta and LinkedIn (through their Conversions APIs), where configured.
Questions, answered
Cost per lead divides ad spend by every lead received. Cost per qualified lead divides the same spend by only the leads that met your qualification criteria. In B2B the two often rank campaigns differently: a campaign with cheap leads can have the most expensive qualified leads if few of them progress.
An offline conversion is a business outcome that happens outside the ad click and website, such as a qualified call, a quote or a closed deal, sent back to Google, Meta or LinkedIn and matched to the original ad interaction. It lets platforms measure and, where supported, optimise towards outcomes beyond form fills.
A marketing-qualified lead is one marketing believes is worth passing to sales, based on fit and engagement. A sales-qualified lead is one sales has contacted and confirmed as a real potential buyer. For paid ads, SQLs are usually a stronger optimisation signal, but they arrive later and in smaller numbers.
Send the earliest stage that reliably predicts revenue and arrives quickly and often enough for the platform’s requirements. A deeper stage like a won deal isn’t automatically better if it takes months or happens rarely; use it to review campaigns instead.
