GOOGLE ADS DATA STRENGTH: FEED THE BIDDING REAL OUTCOMES
On October 13, 2026 Search Engine Roundtable reported that Google rewrote its Data Strength best practices for Google Ads. The new version is a detailed implementation guide focused on first-party data: enhanced conversions, customer lists, Data Manager and tracking that ties a click to a real lead or sale. In plain terms, automated bidding is only as smart as the conversions you tell it about.
AT A GLANCE
By Conqueror Capital · Published
The short answer: Google wants advertisers to send better first-party data, such as hashed emails and phone numbers from leads, transaction IDs and click IDs, so its AI bidding can learn from real results. Start by listing what your account counts as a conversion, check that each one is worth money, confirm enhanced conversions work, and make sure calls and form leads from your website are tracked back to the ad.
WHAT GOOGLE CHANGED
Search Engine Roundtable reported that Google revamped its Data Strength best practices help document, with much greater emphasis on sending first-party data and identifiers, using Data Manager correctly and adopting AI-powered campaigns. The old page was a short overview; the new one is a detailed implementation guide.12
According to the report, the document lists signals advertisers should pass to improve measurement: hashed email addresses and phone numbers, IP addresses, transaction IDs, the Google Click ID (GCLID) and session attributes and URL parameters (GBRAID and WBRAID). It also adds a Data Manager checklist and diagnostics for finding setup errors.1
WHY IT MATTERS
Smart Bidding, Performance Max and AI Max decide who sees your ads based on the conversions you report. If your account counts page views or button clicks as conversions, the system learns to find more page views and button clicks. If it counts qualified leads and sales, it learns to find more of those.
First-party data is information your business collects directly, such as the email or phone number someone enters in your form. Sent to Google in hashed form through enhanced conversions or Data Manager, it helps Google match more conversions to the ads that caused them, especially when browser cookies are missing.
A REVIEW FOR ANY ACCOUNT
- List every conversion action. In Google Ads, open Goals and write down what is counted, and which actions are set as primary (used for bidding).
- Ask: is each one worth money? A call over a minute, a booked appointment or a paid order usually is. A page view usually is not. Make weak actions secondary.
- Check enhanced conversions. Confirm they are turned on and the diagnostics show no errors.
- Track calls and forms from the website. Each lead from your site should be recorded and tied back to the ad click. Our guide to tracking phone calls from Google walks through calls.
- Feed back what happened next. If you know which leads became customers, importing those results tells Google which clicks really paid off.
- Get consent right. Make sure your privacy policy and consent banner cover sharing hashed customer data with advertising platforms where the law requires it.
FOR SMALL BUSINESSES
You do not need every item in Google's guide. For most local businesses the essentials are: real conversions only (calls, forms, bookings), enhanced conversions switched on, and call tracking that works. Our guide to setting up Google Analytics 4 covers the measurement side.
FOR MID-SIZE AND ENTERPRISE ACCOUNTS
- Connect the CRM. Send lead stages and closed deals back to Google Ads, with values, so bidding follows revenue, not form fills.
- One source of truth. Google's guide warns about duplicate Analytics data connections. Make sure each conversion is counted once.
- Use Data Manager diagnostics across every account and location, and fix errors on a schedule.
- Agree governance. Decide who owns tags, consent and customer lists, and document it.

FAQ
What is Data Strength in Google Ads?
It is Google's guidance on the quality of the conversion and customer data you send to Google Ads. Google updated the best practices document in October 2026 with a focus on first-party data.
What first-party data does Google want?
The updated document lists hashed email addresses and phone numbers, IP addresses, transaction IDs, the Google Click ID and session attributes and URL parameters.
What are enhanced conversions?
A Google Ads feature that sends hashed customer details, like the email entered in a form, to help match conversions to ad clicks more accurately.
Should page views count as conversions?
Usually not as a primary conversion. Bidding learns from what you count, so primary conversions should be actions worth money, like calls, bookings and sales.
