Short answer
An offline conversion import sends outcomes recorded in your CRM — a lead marked qualified, an opportunity created, a deal won — back to Google Ads or LinkedIn Ads, matched to the original click or user. The platform can then bid toward leads that turned into pipeline rather than every form submission. It needs a click ID or hashed email captured at lead time and a consistent CRM stage definition.
B2B sales cycles run for weeks or months, and most form fills never become an opportunity. Without CRM feedback, Google and LinkedIn treat a student downloading a whitepaper the same as a VP requesting a demo. Offline conversions are how you tell them the difference.
What you need before you start
- Capture identifiers at lead time: the gclid (Google click ID) in a hidden form field, and the lead's email for enhanced conversions for leads and LinkedIn matching.
- Store them on the CRM record so they survive until the lead is qualified.
- Agree CRM stage definitions with sales: what exactly makes a lead "qualified" or an "opportunity". If the definition changes monthly, the data teaches bidding noise.
Which stages to send
Send the stage that is deep enough to mean quality but frequent enough to give the platform volume. Closed-won deals may happen five times a month — too few to optimise on. Sales-qualified leads may happen fifty times — usually workable.
| CRM stage | Platform conversion | Use in bidding |
|---|---|---|
| Form submitted | Lead (website tag) | Secondary once offline data flows |
| Sales-qualified lead | Qualified lead (offline) | Primary |
| Opportunity created | Opportunity (offline, with value) | Primary or value-based |
| Closed won | Deal (offline, with revenue) | Reporting; value if volume allows |
How the data gets to the platforms
Options range from a scheduled CSV upload, to a native CRM integration (HubSpot and Salesforce both connect to Google Ads), to an automation tool or a small server job calling the platform APIs. For LinkedIn, the Conversions API or CRM integrations do the same job. Choose the simplest option that runs reliably without someone remembering to upload a file.
Uploads must arrive within the platform's lookback window — Google Ads accepts offline conversions up to 90 days after the click — so long cycles favour sending an earlier stage.
Example: a B2B software company
A company generates 200 demo requests a month from Google Ads, of which sales qualifies about a quarter. Bidding on demo requests rewards the campaigns producing the cheapest requests, which are often the least qualified. After importing "sales-qualified" as the primary conversion, campaigns are judged on qualified leads and cost per qualified lead — a different, and more honest, ranking of what works. (This is an illustrative scenario, not a client result.)
Common mistakes
- Losing the gclid because the form tool drops hidden fields or a redirect strips URL parameters.
- Sending the same deal as several conversions when it moves stages back and forth.
- Switching bidding to the offline conversion before there is enough volume — keep it as secondary and observe first.
This CRM-to-platform loop is central to B2B lead generation and B2B PPC work, and is often set up as part of conversion tracking.
Frequently asked questions
- Do I need a CRM for offline conversion imports?
- You need somewhere that records lead outcomes with the original identifiers. A CRM is the usual place; a well-maintained spreadsheet can work for low volume.
- How long before bidding improves after importing offline conversions?
- It depends on volume and sales-cycle length. Expect to observe the data as a secondary conversion for several weeks before relying on it for bidding. Improvement is not guaranteed; the data makes better decisions possible.
- Does LinkedIn support offline conversions?
- Yes. LinkedIn accepts offline and CRM-sourced conversions through its Conversions API, direct CRM integrations and file uploads, matched mainly on email.
