Tracking Offline Conversions: A Guide to Accounting for Sales Outside Your Website (Including Lead Qualification and Long Sales Cycles)

In some industries, making a purchase or signing a contract can take weeks rather than days. A customer might first learn about your offer, then speak with a sales rep, discuss the details, and only later make a decision. In these cases, some conversions (sales) happen directly through the sales team or offline, rather than immediately on your website.

If you don’t report such "delayed" or "offsite" conversions to your ad platforms, they might misjudge your campaigns' performance. That’s why tracking offline conversions is so crucial—it allows you to attribute those sales back to the specific clicks and campaigns that drove them.

1. What Are Offline Conversions, and Why Are They Important?

‍

Offline conversions refer to sales, deals, or actions that happen after a website visit but are finalized outside the internet (via phone, in-person meetings, office visits, etc.).

Why this matters: If all your sales are completed online (like in an e-commerce cart), your analytics automatically tracks them. But when customers take time to decide and pay, for example, via an invoice, it’s essential to inform the ad platform that the visit ultimately led to revenue.

2. Industries With Long Sales Cycles

‍

Some industries naturally have longer decision-making processes, such as:

• B2B and IT
  Clients may visit your site multiple times, communicate with a sales rep, and test a demo version. This can take 1–2 weeks—or even a month.
• Construction and Real Estate
  Buying a property or signing a contract for renovations usually involves consultations, site visits, and approvals.
• Furniture, Equipment, and Medical Services
  High-ticket items or services require detailed discussions before purchase.
• Education Programs
  Customers may take weeks to consider programs, explore schedules, or attend trial sessions.

In all these cases, you need to understand which ad channel initially brought in the customer, even if the purchase happened much later.

3. Lead Qualification: Not All Leads Are Equal

‍

In sales, there’s often a qualification process:

1. Initial Contact: A visit to your website, a phone call, or a form submission.
2. Sales Rep Interaction: The sales rep identifies the lead’s needs, budget, and seriousness.
3. Qualification: If the lead meets all criteria, they’re considered valuable. Otherwise, unqualified leads (e.g., low budgets or irrelevant needs) are filtered out.

If you treat every inquiry as a "conversion," your ad campaigns may optimize for low-quality leads. It’s better to report only qualified leads to ad platforms—those who are genuinely ready to move forward.

4. How to Track Offline Conversions in Analytics

‍

To link offline conversions to specific ad clicks, you’ll need:

• Click IDs (gclid/yclid)
  • From Google Ads: gclid
  • From Microsoft Ads or other platforms: yclid
    These parameters identify which exact ad click led to a website visit.
• Analytics Systems
  Use tools (like a CRM or cross-channel analytics platform) that connect the visitor's click to the eventual sale.
  When the sale is complete, update the lead’s status in the CRM or analytics system to reflect that the inquiry resulted in a sale.
• Data Upload to Ad Platforms
  Your system sends the data back to Google Ads or other platforms:
  • For example, “gclid=12345 resulted in a $5,000 offline sale.”
    Make sure to upload data within the time limit (e.g., Google allows up to 90 days).
• Sale Amount (Optional)
  If the platform supports revenue-based optimization, including the sale amount helps it learn which clicks lead to higher-value sales.

5. Example Workflow

1. A customer clicks on your ad after searching for a service (Google Ads → gclid=12345).
2. They visit your website and submit an inquiry form.
3. Over the next week, your sales team communicates with the customer, answers questions, and closes a deal worth $15,000.
4. The sales rep marks the deal as “closed” in the CRM or analytics platform.
5. The system sends a report back to Google Ads: gclid=12345 → offline conversion: $15,000.
6. Google Ads recognizes that this ad, keyword, and targeting led to a valuable sale and prioritizes similar prospects in future campaigns.

6. How UTM Tags Tie In

‍

To track other traffic sources beyond Google Ads or Microsoft Ads (e.g., social media, email campaigns, or partner referrals), use UTM tags:

• utm_source: Identifies the traffic source (e.g., Facebook, email).
• utm_medium: Indicates the type of traffic (e.g., cpc, organic, social).
• utm_campaign: Tracks the specific campaign name.

7. Conclusion

‍

Offline conversions provide a more accurate view of your ad campaigns' performance when deals take time to close. By reporting data on qualified leads (and optionally their deal value) to your analytics platform and ad networks, you allow these systems to optimize for high-value customers—not just any inquiry.

‍

For businesses with long sales cycles, this is critical. Without it, your advertising strategy may miss the mark by prioritizing low-quality leads.

If you haven’t yet set up basic analytics and UTM tags, be sure to start there—these tools give you the foundation to track offline sales effectively and maximize your marketing ROI.
