Enhanced conversions in Google Ads send first-party customer data, like an email or phone number, along with your conversion tag. Google uses it to match sales and leads back to ad clicks, even when cookies fail. From November 16, 2026, Google Ads Data Manager will no longer require that data to be hashed before upload.
If you run lead generation or e-commerce ads, this change touches how you send customer lists and offline sales to Google. Here is what it means in plain words.

What Are Enhanced Conversions in Google Ads?
Enhanced conversions are a Google Ads feature that improves conversion tracking with data your customers give you, such as email, phone, name or address. The data is sent with your conversion tag, matched to signed-in Google accounts, and linked to the ad click that drove the sale or lead.
Google says the feature can improve the accuracy of your conversion measurement and unlock more powerful bidding. That matters because Smart Bidding learns from conversions. Missing conversions mean weaker bids.
Enhanced conversions for web
A customer clicks your ad and buys on your site. The tag sends their details with the purchase.
Enhanced conversions for leads
A customer fills a form, and the sale happens later on call, WhatsApp or in person. You upload the result back to Google.
Google's help page on enhanced conversions for leads explains that customer data is compared with signed-in Google accounts to measure conversions driven by your campaign.
What Changes in Google Ads Data Manager on November 16?
From November 16, 2026, Google Ads Data Manager stops requiring customer data to be hashed with SHA-256. It will accept encrypted data by default instead. Google then decrypts, cleans and matches the data inside a sealed processing environment. The change applies to Customer Match and enhanced conversions.
According to PPC Land, Google told advertisers by email that it will support encrypted customer data by default from that date. The update was first spotted by PPC specialist Anthony Higman. German publication Dr. Web reported the email has been public since October 18.
| Until Nov 15, 2026 | From Nov 16, 2026 | |
|---|---|---|
| What you upload | SHA-256 hashed values | Encrypted customer data |
| Who formats the data | You | Google, inside a sealed environment |
| Features affected | Customer Match, enhanced conversions | Same |
| Input routes | CRM links, cloud storage, file upload, Data Manager API | Same |
What is still unclear
Google's email does not say whether existing scheduled uploads of SHA-256 hashes will keep working unchanged, according to PPC Land. It also does not mention Display & Video 360 or Google Analytics. Check your Data Manager connections after November 16 rather than assuming.
Data Manager vs Enhanced Conversions: What's the Difference?
Enhanced conversions send customer data at the moment of each conversion to improve tracking. Data Manager is a batch tool for bigger data jobs: uploading customer lists for Customer Match, importing offline conversions from a CRM and connecting cloud storage. Most businesses need enhanced conversions first and Data Manager when offline sales grow.
| Tool | What it does | Best for |
|---|---|---|
| Enhanced conversions for web | Sends customer data with each online conversion | E-commerce, online bookings |
| Enhanced conversions for leads | Matches later offline sales to form leads | Courses, real estate, clinics, B2B |
| Customer Match | Uploads customer lists for targeting | Remarketing and exclusions |
| Data Manager | One place to connect CRM, files and storage | Regular batch uploads |
For Indian lead-generation businesses, enhanced conversions for leads is the big one. A Mysore institute or a Bengaluru builder usually closes the sale on a phone call or campus visit. Without offline conversion tracking in Google Ads, the platform never learns which clicks became real customers.
How to Set Up Enhanced Conversions Step by Step
You turn on enhanced conversions in Google Ads first, then make sure your website passes customer data to the tag. In 2026, Google simplified this into a single toggle under the Customer data use section, at both account and conversion action level. The whole setup takes under an hour if your tag is already in place.
Steps in Google Ads
- Go to Goals, then Settings.
- Find the Customer data use section.
- Turn on enhanced conversions.
- Accept Google's customer data terms.
Steps on your website
- If you use Google Tag Manager, map the email and phone fields from your form or checkout page.
- If you use the Google tag directly, pass the user data before the conversion fires. The tag normalises and hashes it.
- Test with a real form fill and check the diagnostics tab after 48 to 72 hours.
Common mistakes to avoid
- Turning it on in Google Ads but not mapping the form fields. Nothing gets matched.
- Ignoring consent. Consent Mode v2 still governs website data.
- Uploading offline sales once and forgetting. Schedule it weekly.

Frequently Asked Questions
What is enhanced conversions in Google Ads?
Enhanced conversions is a Google Ads feature that sends first-party customer data, such as email or phone, with your conversion tag. Google matches it with signed-in accounts to connect conversions to ad clicks, improving measurement and bidding when cookies are blocked.
What changes in Google Ads Data Manager on November 16, 2026?
From November 16, 2026, Data Manager no longer requires SHA-256 hashed customer data. It accepts encrypted data by default and handles decryption, formatting and matching itself. Customer Match and enhanced conversions are the features named in Google's email to advertisers.
Do I still need to hash customer data?
For Data Manager uploads after November 16, 2026, hashing is no longer required. For website tags, the Google tag already hashes values automatically if you pass them unhashed. Check each connection, because Google has not confirmed how existing hashed uploads will be treated.
Is enhanced conversions useful for lead generation businesses?
Yes. Enhanced conversions for leads is often more valuable for lead businesses than for e-commerce. It lets Google learn which form leads became paying customers offline, so Smart Bidding can find more people like them.
How long does enhanced conversions take to start working?
Data usually appears in diagnostics within 48 to 72 hours of setup. Bidding improvements take longer, often a few weeks, because Smart Bidding needs enough matched conversions to learn from.
Conclusion
Enhanced conversions are now basic hygiene for any Google Ads account, and the November 16 Data Manager change makes uploading customer data simpler. Turn on the toggle, map your form fields, schedule offline uploads and update your privacy wording. Better data means better bids, especially as Google pushes ads into Google AI Mode ads and other AI surfaces.
