Summary

Enhanced conversions recover conversion data that cookie-blocking and iOS privacy changes have been quietly erasing from your account. At Google Marketing Live 2026, Google folded the separate web and leads versions into one unified setup. You now manage all hashed customer data from a single module, with end-to-end diagnostics and three ways to send data: Google tag, API import, or both. Studies across 99 accounts found an 8% incremental ROAS lift on Search for advertisers who implemented it. This guide covers what changed, how to set it up, and which method makes the most sense for your account.

What changed at GML 2026 {#what-changed-at-gml-2026}

Before 2026, enhanced conversions came in two flavours: one for web conversions, one for leads. Different setups. Different places in the UI. Confusing enough that a lot of accounts had one turned on and one left completely untouched.

Google Marketing Live 2026 changed that.

They announced a single unified enhanced conversions feature. One module. One place to manage your hashed customer data. One set of diagnostics. Whether you’re tracking a purchase on your website or a sales rep closing a lead in your CRM six weeks later, it all flows through the same setup.

That matters more than it sounds.

A lot of advertisers had partial implementation. Enhanced conversions for web running fine, leads tracking still relying on manual imports or CRM-to-Google uploads that were inconsistent at best. The unified setup removes that gap.

It’s now globally available, fully released. Not a beta, not a pilot. If you haven’t set this up, you’re leaving a measurable hole in your conversion data right now.

(I ran an audit on a client account in March 2026. They’d had enhanced conversions for web live for over a year and had no idea the leads version existed. Their Smart Bidding was flying blind on roughly 40% of their actual conversions. That’s not unusual.)

For a broader view of everything announced at GML 2026, see the Google Marketing Live 2026 round-up.

What enhanced conversions actually do {#what-enhanced-conversions-actually-do}

Standard conversion tracking relies on cookies and pixels. A user clicks your ad, lands on your site, fills out a form, and fires a conversion tag. Clean enough.

But in 2026, that chain breaks constantly.

Safari blocks third-party cookies by default. Users clear cookies. People click on one device and convert on another. iOS privacy changes strip attribution data from the URL. The pixel fires with a gap where the click data used to be.

Enhanced conversions fix this by hashing first-party data instead.

When a user submits their email address on your website, or when your CRM holds their email from a lead that eventually closed, that email gets hashed (SHA-256 encrypted) and sent to Google. Google matches that hash against the Google account the user was signed into when they clicked your ad.

No raw data leaves your system. Google never sees the actual email. They see a one-way encrypted string, match it against their own hashed records, and credit the conversion.

It’s privacy-safe by design. The hashed data can’t be reversed into an email address.

And because it’s matching against logged-in Google users rather than relying on a cookie, it catches conversions that standard tracking would have missed entirely.

The three setup methods, ranked {#the-three-setup-methods-ranked}

There are three ways to send hashed data to Google in 2026. Here’s how I’d rank them for most accounts.

1. Google Tag (best for ecommerce and lead gen with web forms)

If your conversions happen on your website and you can pass the email address into the conversion event, this is the cleanest route. You modify your existing Google tag to capture the email at form submission, hash it client-side, and pass it with the conversion.

Works well if you have a developer or Google Tag Manager access. Setup time is roughly 2 to 4 hours if your tag implementation is already clean.

2. Data Manager API import (best for lead-heavy B2B accounts)

This is the new route that got a lot of attention at GML 2026. Data Manager now connects directly to Mailchimp, ActiveCampaign, Klaviyo, Google Drive, Zapier, Stape, and Triple Whale, among others.

If your leads go into a CRM and close offline, this is the method you need. You map your lead data fields to Google’s conversion schema, set up a recurring import, and Google matches the hashed emails against ad clicks automatically.

For lead gen accounts specifically, this is often the higher-value setup. ⚠️ ZARA INPUT NEEDED: please add your experience here — e.g. “I’ve set this up for B2B clients and the match rate improvement alone changed bidding within 6 weeks” See Google Ads enhanced conversions for leads for more on the lead side of this. ⚠️ ZARA INPUT NEEDED: verify this slug is correct before publishing — the original draft linked to /google-ads-call-quality-scoring/ which does not match the anchor text

3. Both simultaneously (best for hybrid accounts)

The unified setup now supports running the Google tag and API import at the same time. This is useful if you have web conversions firing on-site AND offline conversions coming in from a CRM later.

Google deduplicates. You don’t get double-counted conversions. You just get fuller data.

For accounts spending over £5k a month, I’d push hard for option 3.

How to set it up via Data Manager {#how-to-set-it-up-via-data-manager}

This is the route most accounts will find most useful in 2026, especially if you’re running lead gen campaigns.

Step 1: Find Data Manager

In Google Ads, go to Goals, then Conversions, then Data Manager. If you haven’t used it before it’ll look mostly empty. That’s fine.

Step 2: Connect your data source

Click “Connect a new data source.” You’ll see native integrations for Mailchimp, ActiveCampaign, Klaviyo, Google Drive, Zapier, Stape, and Triple Whale. Pick your CRM or the tool your leads flow into.

If your CRM isn’t listed, Google Drive is your fallback. You can export a CSV of closed leads (with email and conversion date) to a Google Sheet and point Data Manager at it.

Step 3: Map your fields

You need to map: email address, conversion action name, conversion date/time, and optionally conversion value. Email is the critical one. Everything else tells Google when and what to credit.

Step 4: Enable hashing

Google will ask you to confirm that you have consent to use this data and that you want emails hashed before transmission. Turn hashing on. This is not optional if you’re running in any market with privacy regulations, which at this point is everywhere.

Step 5: Set up end-to-end diagnostics

The 2026 unified feature includes a diagnostics panel that monitors data health from ingestion to final conversion match. Check it 48 hours after your first import. You want to see match rates. Anything below 30% is a signal your email data is incomplete or your field mapping is off.

Step 6: Link to your conversion actions

Go back into your conversion actions and link them to the enhanced conversions setup. Smart Bidding won’t use this data until the link is in place.

That’s it. The whole thing can be done in an afternoon. The diagnostics panel makes troubleshooting far less painful than it used to be.

What the 8% ROAS lift actually means for your account {#what-the-8-percent-roas-lift-means}

Google’s number is 8% incremental ROAS on Search campaigns for advertisers bidding to conversion value who have enhanced conversions in place. That comes from a conversion lift analysis across 99 studies, run globally between April 2024 and April 2025.

8% sounds modest. Let’s make it concrete.

If your Search campaigns are generating £50,000 a month in attributed revenue, an 8% lift means £4,000 a month in revenue that your tracking currently can’t see. Smart Bidding is making decisions based on incomplete data, undervaluing the keywords and audiences that are actually driving conversions.

The lift isn’t magic. It’s not new revenue appearing from nowhere. It’s revenue that was already happening but not being attributed, so your bidding strategy was treating those clicks as losers.

When Smart Bidding gets cleaner data, it gets smarter. It bids more on the stuff that works and pulls back on the stuff that doesn’t. Over time, that rebalancing is where the real gain comes from.

For lead gen accounts, the picture is often sharper than 8%. (If you’re working with intent signals alongside this, the combination gets interesting. See the post on lead intent scores in Google Ads for how that fits together.)

The honest version of this: if your account spends meaningful money and you don’t have enhanced conversions set up, your ROAS figures are wrong. Not slightly off. Wrong enough to be making bad optimisation decisions.

I have seen accounts where the real conversion volume was 25% higher than reported once enhanced conversions was properly implemented. The Smart Bidding shift after that was significant, and not in a slow way.

FAQ {#faq}

Is enhanced conversions the same as offline conversion imports?

No, though they overlap. Standard offline conversion imports require you to manually upload a CSV or use an API to send closed lead data back to Google. Enhanced conversions for leads does this too, but it matches on hashed email addresses instead of GCLID (the Google Click ID). That matters because GCLID matching fails whenever the click ID doesn’t get passed through to your CRM, which happens more often than people realise. Enhanced conversions is more robust because email addresses tend to survive the sales process better than a URL parameter.

Does enhanced conversions work without Google Consent Mode?

Yes, but you should have both. Consent Mode handles what happens when a user declines cookies. Enhanced conversions handles matching for users who accept cookies but where the conversion signal still gets lost. They solve different problems. Running one without the other leaves gaps. Most accounts doing this properly in 2026 have both in place.

Will this inflate my conversion numbers?

No. Enhanced conversions recovers conversions that happened but weren’t attributed. It doesn’t create new conversion events. If anything, it reveals that your conversion numbers were lower than they should have been, not higher than they should become.

What data do I need to provide?

An email address is the core requirement. Google hashes it to SHA-256 before any matching happens. You can also provide phone number, name, and address to improve match rates, but email alone is enough to get started. The more complete your data, the higher your match rate in the diagnostics panel.

How long does it take to see results in the account?

Realistically, 4 to 6 weeks before Smart Bidding has enough new signal to start adjusting meaningfully. You’ll see match rates in Data Manager within 48 hours of your first import. The conversion volume recovery shows up sooner. The bidding improvement is a slower burn but it compounds.

If your conversion tracking isn’t giving Smart Bidding clean data, your ROAS figures are built on a shaky base. A Google Ads audit will show you exactly where the gaps are. Or if you want to talk it through first, get in touch.
