The GTM half of the job
“Allow user provided data capabilities” has to be enabled on the Google tag before it can send anything useful, and Google Ads won’t do that for you.
Ticking the box in Google Ads was the easy half
Turning on enhanced conversions in Google Ads doesn’t configure your tag. We finish the job in Google Tag Manager, then serve your Google tags from your own domain with Google tag gateway.
From £750 ex VATWhy aren’t my enhanced conversions working?
A collection method that suits your forms
Automatic detection, CSS selectors, JavaScript variables or a code snippet. Google warns that data sent differently from what you chose in Google Ads “may not be processed”.
Web and leads, one setting
Google said web and leads would share a single on/off setting from June 2026, so we check what yours now does instead of assuming.
Customer data terms
These must be accepted before anything else works. A small step that catches out more accounts than it deserves to.
Diagnostics, read properly
Google’s diagnostics appear about 48 hours after implementation, so we come back and read them rather than declaring victory on the day.
Whichever CDN you’re on
Cloudflare has a free one-click integration on any plan. Google also lists Akamai, Fastly, Google Cloud Load Balancer and Amazon CloudFront, with varying amounts of manual work.
From a ticked box to data Google can use
Every field checked at the moment the tag fires
Email, phone and address only count if they’re available when the tag runs. We test each form on your real journey and confirm the hashed values are actually leaving the browser.
- Email and phone captured at the right moment
- Hashed before leaving the browser
- Tested on your real forms
Tag gateway, minus the consent trap
Google tag gateway serves your Google tags from a path on your own domain, so measurement goes first-party before being forwarded to Google. Google’s help says “If you use consent mode, you must turn off automated script set up”, which means the one-click route isn’t always the right one.
- Set zone-wide on Cloudflare
- Automated script setup checked against consent
- Visitors still have to consent
What uplift should I expect from enhanced conversions?
We couldn’t find an official figure from Google, so we won’t quote one. The only number we’ll repeat is Cloudflare’s own: early testers of its tag gateway saw “on average an 11% uplift in data signals”, which measures signals rather than sales.
- No invented percentages
- Cloudflare’s figure, credited to Cloudflare
- Your own numbers, compared before and after
