Enhanced conversions for leads is a Google Ads feature that matches an offline sale back to the original ad click using the lead's hashed email address instead of a click ID.
Enhanced conversions for leads lets you report an offline conversion using the contact details someone typed into your form. Google hashes the email address, which scrambles it into a code that cannot be read back, and matches it to the signed-in Google account that clicked your ad.
It is a different route to the same destination as GCLID tracking. You are still telling Google that a click became a customer. You are just using the email as the key instead of the click ID.
[table]
| Enhanced conversions for leads | GCLID offline import
What links the sale to the click | Hashed email from the form | The click ID in the URL
Needs a hidden form field | No | Yes
Needs the field kept through the CRM | No, email is already there | Yes, and this is where it usually breaks
Setup effort | Lower. Tag or Google Ads API | Higher. Form, CRM and import
Match rate | Depends on personal versus work email | High when the ID survives
Best answer | Run both | They cover each other's gaps

The whole problem in B2B measurement is the gap between the click and the money.
Someone clicks an ad in March and signs a contract in May. Google sees the click. It never sees the contract. So the bidding keeps optimising toward form fills, because that is the only outcome it can observe.
Enhanced conversions for leads closes that gap without asking your developer to plumb a click ID through five CRM stages. The email is already on the record. You send it back when the stage changes, and Google learns which clicks turn into revenue.
That is the change that lets you bid on SQLs and closed deals instead of on form fills.
Google hashes the email before it is sent. The raw address never reaches Google in readable form, which is what makes this acceptable under most privacy rules. Our offline conversion tracking guide covers the full build.
Two issues come up often.
The match rate is lower than expected and nobody investigates. Google matches the hashed work email against signed-in Google accounts. If your buyers use work emails on Microsoft accounts, the match rate drops. That is normal and not a mistake. Run GCLID tracking alongside so the gaps get covered.
Only closed won is uploaded. Deals take months. If the only thing you send back is a closed deal, the algorithm gets a handful of signals a quarter, which is not enough to learn from. Send SQL back too. It arrives sooner and there is far more of it.
Turn it on, send back SQLs as well as closed deals, and run it alongside GCLID tracking.
This is one of the cheapest high-value changes available in a B2B Google Ads account. It takes a few hours and it changes what the bidding is chasing.
Send two signals, not one. SQL, which arrives in days or weeks and gives the algorithm volume to learn from. And closed won with the real contract value, which arrives later and teaches it what a good customer looks like.
Do not treat this as a replacement for click ID tracking, or for the broader enhanced conversions setup on your website forms. The methods fail in different situations. Running them together means fewer deals go unmatched, and in B2B every matched deal counts because there are so few of them.
A Google Ads feature that ties an offline sale back to the ad click using the lead's hashed email address. It lets you report a closed deal weeks later and have Google credit it to the right campaign.
The email is hashed before it leaves your site, which turns it into a code that cannot be reversed. Google never receives the readable address. This is what allows the feature to work within most privacy rules.
Regular enhanced conversions improve the accuracy of conversions that already happen on your site. The leads version handles conversions that happen later and offline, such as a deal closing in your CRM two months after the click.
Yes, ideally. The two methods fail in different ways. Email matching depends on the buyer having a Google-linked account, and click ID tracking depends on the ID surviving your CRM. Running both covers more deals.
Send the SQL stage as well as closed won. SQLs arrive within days or weeks and there are far more of them, which gives the bidding algorithm enough data to learn from. Closed won teaches it what a good customer is worth.
