Yes β but not with browser tracking. Standard cookies and pixels usually expire or get blocked long before a multi-week sales cycle ends. Deep Conversions persists a signed 90-day buyer journey on the server and connects the original ad click to the verified payment when it finally happens.
Why Week-Later Sales Vanish From Your Ad Platforms
Considered purchases β B2B software, high-ticket services, medical devices, courses β rarely convert on the first session. The tracking breaks down in three predictable ways:
- Cookie Expiration: Most ad platform cookies and browser cookies are engineered for 7-to-30-day windows. Your 3-week enterprise deal outruns them.
- Multi-Device Journeys: The buyer researches on their phone at night and purchases from their work laptop. A browser-only record cannot follow that switch.
- PrivacyζΈ Blocking: Safari ITP caps javascript cookies at 7 days for many visitors, and Brave or Firefox ETP delete them outright.
Your ads manager concludes the campaign produced nothing, you cut the budget, and the pipeline that campaign was feeding quietly dries up two weeks later.
| Sales Cycle Length | Browser Cookie Survival | Server-Side 90-Day Journey |
|---|---|---|
| Same-day purchase | Usually tracked | Tracked + payment-verified |
| 1-4 week cycle | Partially lost (ITP, clearing, device switch) | Fully connected |
| 1-3 month enterprise cycle | Almost always lost | Fully connected with verified receipts |
How to Track Long-Cycle Sales Correctly
- Move Journey State Server-Side: Record the first ad click (gclid, fbclid, rdt_cid, ttclid) in a signed server-side record the day it happens.
- Keep the Record Tenant-Scoped: Every repeat visit, content view, and checkout attempt attaches to the same journey for 90 days.
- Close the Loop at Payment: When the customer finally pays, verify the payment cryptographically before reporting anything.
- Feed the Full Journey to Your Ad Platforms: Deliver the verified purchase with the original click IDs so bidding models learn which campaigns start real deals.
Deep Conversions keeps a signed 90-day journey from first click to verified payment and delivers the Purchase event server-side with original attribution β the way long sales cycles actually behave.
Connect My Long Sales Cycles βFrequently Asked Questions
What happens if the buyer switches devices mid-journey?
The journey lives server-side rather than in one browser, so repeat visits from other devices attach to the same signed record instead of starting a new anonymous session.
Is a 90-day window configurable?
The signed journey is designed to cover typical enterprise and high-ticket cycles within a 90-day persistence window, longer than the 7-30 day limits of browser cookies.
Does this replace my CRM attribution?
It complements it: the CRM shows your sales team the pipeline, while Deep Conversions reports verified revenue back to the ad platforms themselves, which is what their bidding algorithms actually consume.
