Have your Google Ads conversions suddenly dropped?

Maybe your campaigns were generating enquiries consistently, and then the numbers started falling. Or perhaps your phone is still ringing and leads are coming through, but Google Ads is reporting far fewer conversions than you expect.

Before you start changing bids, pausing campaigns or increasing your budget, there is something important to check: your conversion tracking.

Google has made changes to its enhanced conversion setup in 2026, including bringing enhanced conversions for web and leads into a more unified system. Google has also changed how certain offline conversion and enhanced conversion for leads data is uploaded.

That doesn't mean Google's changes are automatically responsible for a sudden drop in your results. A decline can have many causes, from campaign performance and competition to website issues or broken tags. But if the numbers suddenly don't look right, your tracking setup should be one of the first things you investigate.

At Jumpp Media, we focus on the numbers that actually matter to your business — leads, customers and revenue. So, let's look at what has changed and what you should check.

Has Google Changed Conversion Tracking in 2026?

Yes. Google has made several important changes to enhanced conversions during 2026.

Starting in April 2026, Google Ads began allowing user-provided data to be accepted simultaneously from website tags, Data Manager and API connections. Google then moved towards combining enhanced conversions for web and enhanced conversions for leads into a single feature with a simpler on/off setting.

Existing eligible enhanced conversion users are automatically migrated to the unified status, provided the required customer data terms have previously been accepted.

There is another important change for advertisers using offline data.

From 15 June 2026, Google says offline conversion imports and enhanced conversions for leads uploads are being migrated to the Data Manager API and blocked in the Google Ads API, subject to limited legacy-access conditions.

The key point is simple: Google's measurement ecosystem continues to evolve, so an advertising setup that was working previously shouldn't simply be assumed to be configured optimally today.

What Are Enhanced Conversions?

Enhanced conversions improve the accuracy of Google Ads conversion measurement by using first-party customer data such as email addresses or phone numbers (hashed before being sent to Google).

They help connect ad interactions to real business outcomes, such as enquiries or purchases.

For example:

• A user clicks your Google Ad
• Visits your website
• Submits an enquiry
• Later becomes a customer

Enhanced conversions help attribute that outcome back to the ad interaction.

Why Accurate Google Ads Conversion Tracking Matters

Google Ads relies heavily on automated bidding systems that depend on conversion data.

If your tracking is inaccurate, your optimisation is also affected.

For example:

• Under-reporting conversions leads to under-optimisation
• Over-reporting conversions leads to wasted spend

This is why Jumpp Media focuses on conversions, not just clicks.

Signs Your Google Ads Conversion Tracking May Have a Problem

• Conversions suddenly drop to zero or near zero

What to Do If Your Google Ads Conversions Have Dropped
