How to Set-up Offline Conversion Tracking With Google Ads : A Complete 2025 Guide to Bridging Clicks and Real-World Sales

What is Offline Conversion Tracking?

Offline conversion tracking is the process of attributing marketing campaigns, especially paid ads, to sales or actions that happen outside the digital channels. These may include:

• Phone sales
• In-person purchases
• Signed contracts
• Sales meetings booked outside the website

By capturing unique identifiers, such as GCLID, and syncing with CRM or POS systems, marketers can create a feedback loop by sending these offline outcomes back to ad platforms to optimize campaigns basedon real revenue, rather than just clicks or form submissions.

‍

Why Offline Conversion Tracking is Essential 

While SEO and paid media continue to drive website traffic and leads, the biggest challenge for performance marketers remains connecting online engagements to offline sales. 

Traditional conversion tracking stops at the last click or an eventual form fill. But what about when a lead signs a contract after a call, books a demo offline, or makes a purchase in-store? That's where offline conversion tracking comes into play.

Offline conversion tracking with Google Ads enables you to close the loop, aligning your ad spend with actual revenue, allowing you to move beyond reporting just on leads generated. 

ROI transparency is king in every organization, and ensuring your team can track where offline revenue comes from and further enhance your online campaigns, as well as more accurately report on revenue sources, is essential for marketers and SEO strategists alike.

Offline Conversions and SEO: Why It Matters for Organic Strategy Too

Offline tracking is often associated with paid media, but it also has a massive impact on your SEO strategy. Knowing which content leads to real-world conversions helps you prioritize high-value keywords and optimize your editorial calendar.

Benefits for SEO:

• Attribute leads from blog articles or organic pages that result in offline sales.
• Identify high-converting search intents.
• Align SEO performance with pipeline and revenue, not just pageviews.

Offline insights provide your SEO team with the data they need to drive not just traffic, but also sales-qualified leads that lead to revenue.

How Offline Conversion Tracking Works in Google Ads

Offline conversion tracking connects Google Ads engagements to real-world actions through unique click identifiers and synced data uploads.

Key Concepts:

• GCLID (Google Click ID): A unique identifier appended to each ad click.
• Data Flow: Click on an ad → lead fills out a form (GCLID captured) → CRM logs lead → sale happens offline → conversion uploaded back to Google Ads.
• Upload Options: Manual CSV uploads or automated API integrations.
• Enhanced Conversions for Leads (ECL): Privacy-safe alternative when GCLID isn't available.

By syncing your CRM with Google Ads, you can ensure that you're not just tracking clicks, but also going the extra mile and measuring closed deals.

How to Set Up Manual Offline Conversion Tracking in Google Ads

If you're not ready for API automation, you can use Google Ads' manual CSV upload method to track offline conversions.

Steps:

1. Capture the GCLID when someone submits a lead form on your site.
2. Store the GCLID in your CRM associated with the lead.
3. Create a conversion action in Google Ads (see next section).
4. Export a CSV file with the required format: Google Click ID, Conversion Name, Conversion Time, Conversion Value.
5. Go to Google Ads > Goals > Conversions > Uploads.
6. Upload your CSV file and review matching results.

‍

This method helps attribute offline actions to specific campaigns and keywords even without full automation.

‍

Creating or Importing Conversion Actions in Google Ads

Before uploading offline conversions, you must create a corresponding conversion action in your Google Ads account.

How to Create a Conversion Action:

1. Go to Tools & Settings > Conversions.
2. Click the + New conversion action button.
3. Choose Import as the source.
4. Select Other data sources or CRMs and choose "Track conversions from clicks."
5. Set up your conversion details:
   
   • Name (e.g. "Offline Deal Closed")
   • Category (e.g. Purchase or Lead)
   • Value, Count, and Attribution settings
6. Save the conversion action. You can now start uploading matching conversions.

Ensure that the conversion name in your CSV matches the one defined here precisely.
