Your Google team has started saying “Data Strength” in QBRs. Here is what they mean and what to do about it, in the order that matters.
Data Strength is Google’s framework for whether your first-party data can power AI-driven campaigns. Four steps. Connect your data sources. Maximize your signals. Activate Google AI. Prove your ROI. Google’s guidance is public and worth reading, but the CMO translation is shorter: can Google’s models see your real conversions, with real values, legally?
Step one is tagging and pipes
Sitewide tag health, GA4 linked to Ads, and increasingly Google Tag Gateway, which serves the tag from your own domain. Google reports advertisers on Tag Gateway measure 14% more conversions on average. That is recovered signal, not new demand, and it is the cheapest 14% you will find this year.
Step two is what rides on the pipes
Enhanced Conversions attaches hashed emails and phones so conversions match to signed-in users. Consent Mode v2 carries the user’s consent state; without it, Google discards your identifiers for EEA and UK traffic entirely. Transaction IDs and real values separate a purchase from a pageview in the model’s eyes.
Step three is activation
Customer Match audiences from your actual customer list, refreshed automatically, seeding Smart Bidding and new-customer goals. Stale lists are the most common failure here; a quarterly CSV upload is not a data strategy.
Step four is proof
Once conversions are complete and matched, incrementality tests and marketing mix models stop arguing with your dashboards. That is when finance starts trusting marketing numbers, which is worth more than the media efficiency.
Where we fit, stated plainly: Google’s published partner list for Data Strength names Datahash among the partners that enable it, and we are a selected Google Implementation Partner for EMEA. We build steps one and two and wire step three. Your agency and your Google team take it from there.
Start with the baseline. It is one working session and it produces a ranked gap list you can hand to whoever owns the fix.
