Google just put a number on how much conversion data you're leaving on the table. Be skeptical of that number. Then go fix the thing it's measuring anyway.
Both of those are true at once, and most businesses will only hear one of them.
What Google announced
On September 10, 2026, Google published a measurement update from Nipoon Malhotra, its VP of Ads Analytics, Insights, and Measurement. PPC Land's breakdown covers the main pieces:
- A Data Strength Uplift metric in Google Ads. It estimates the extra conversions your first-party data setup recovers, as a number. Google hasn't published how it's calculated.
- Data Manager inside Google Analytics and Display & Video 360. The Data Manager API is now universal and built on the IAB Tech Lab's ECAPI standard, with new diagnostics to catch data problems early.
- Enhanced conversions for Analytics and DV360. Announced in September, though Google's October follow-up described it as "soon available." So check your own account rather than assuming it's there.
Then on October 13, Google's October Demand Gen Drop repeated the pitch. PPC Land's coverage quotes Google PM Alejandro Osio defining "data strength" as three parts: Google tag gateway set up, a CRM linked through Data Manager, and enhanced conversions turned on.
Google attached numbers to all of it. An 11% average lift in Search conversions with enhanced conversions versus standard imports. A 26% average lift in incremental ROAS for advertisers connecting offline and app data through Data Manager. And over 20% more Demand Gen conversions with tag gateway, "based on an internal analysis."
The honest read on those numbers
Every one of those stats comes from Google, about Google's products, and none has been independently checked. PPC Land points out that an earlier 14% tag gateway figure was footnoted to finance-vertical data only. And the uplift metric is calculated by the same company that benefits when you share more data.
There's a deeper point too. A "recovered" conversion is a sale that already happened but wasn't being counted. It's not a new sale. So don't expect revenue to jump 20%.
Here's why you should still care. Bidding systems can only optimize toward conversions they can see. If cookies get blocked, ad blockers eat your tags, or offline sales never make it back to Google Ads, the algorithm is flying half blind. It undervalues the campaigns that actually work and overspends on the ones that happen to be easy to track. Better data doesn't create sales. It stops you from making expensive decisions on wrong numbers.
The setup order we'd use
Do these in order. Each one builds on the last.
-
Accept the customer data terms in Google Ads. Go to Goals, Settings, Customer data use. Nothing else on this list works without it. Read the terms first and make sure your privacy policy actually discloses that you share hashed customer data with Google.
-
Turn on enhanced conversions. Google merged the web and leads versions into one toggle earlier this year. Make sure your forms and checkout pass email (and phone, if you collect it) to the Google tag. In GTM, that means a user-provided data variable mapped to your form fields or data layer.
-
Set up Google tag gateway. Tag gateway loads Google's tags from your own domain, so browsers treat them as first-party. You've got options now. Cloudflare was first. Akamai and Fastly followed. Google Cloud's load balancer went GA on June 1, 2026, and Amazon CloudFront got a guided setup on June 3. If you're on Cloudflare, this is usually the fastest win on the list. Tag gateway doesn't change your consent obligations, so your banner still has to work.
-
Connect your CRM through Data Manager. If you sell through sales calls, quotes or in-store, this is where the real value is. Send qualified leads and closed deals back to Google so it learns which clicks turn into revenue, not just form fills.
-
Check diagnostics weekly for the first month. Look at enhanced conversions match rates and Data Manager diagnostics. A setup that's "on" but sending blank or badly formatted emails isn't helping anyone.
-
Measure against your own baseline, not Google's metric. Before you start, write down conversions, cost per conversion and CRM-reported revenue for the last 30 days. Compare after 30 and 60 days. Use the Data Strength Uplift number as a hint, not as proof.
Who should skip ahead and who should wait
If you run a lead-gen business with a sales team, steps 1, 2 and 4 are where the money is. Lead quality data beats lead volume data every time.
If you're ecommerce on Shopify or WooCommerce, steps 1 to 3 cover most of the gap.
If you're spending a few hundred dollars a month, don't overbuild. Enhanced conversions alone gets you most of the benefit for the least effort.
Takeaway: Ignore the hype numbers, but fix your data foundation anyway, because bidding can only reward the conversions it can see.
