Honest signal. Across every platform you buy from.
Over 80% of paid-media spend is now allocated by ML — Smart Bidding, Performance Max, Advantage+, Smart+. The algorithms are only as good as the signal feeding them. Most of that signal is broken, and the people closest to it can't see it clearly.
datafairy watches your full signal stack — on-site, ad-platform, offline — keeps it honest, and over time operates the automation itself.
Your automation is only as smart as the signal you give it.
Marketers don't tune bids anymore. They tune what the algorithms see. When the signal breaks, the same algorithms keep spending — just on the wrong signals.
What goes wrong, quietly
-
!
Your sales tracking quietly stops working.The checkout still works fine — but Google and Meta can't see the sales. It can go on for weeks before anyone notices.
-
!
Your CRM stops talking to Google Ads.The leads that became real customers never get sent back. Google keeps bidding hard for the wrong people, because nobody told it which ones actually paid.
-
!
Meta and your website disagree on what a sale is.Match quality drops, Advantage+ chases the wrong audiences, and your costs creep up — even though nothing about your campaigns changed.
-
!
Nobody's actually watching.There's no one whose job is "is the signal still firing?" — so it rots while your ad spend keeps running at full speed.
What datafairy actually does
-
✓
Names the gap in plain English.Not "11 findings, severity 4." A specific sentence: "your purchase event stopped firing on the confirmation page yesterday at 2pm."
-
✓
Hand-holds you through every fix.datafairy walks you through each recommendation, ships the change, and gives you the technical detail when you ask.
-
✓
Estimates the automation cost.Every finding carries a real impact on Smart Bidding, Performance Max, Advantage+, or Smart+ — not an abstract severity.

Operates the fix, when you let her.Stages GTM tag changes. Writes them with one-click approval. Rolls back if something regresses.
One AI operator. Three levels of agency.
The same datafairy at every tier — just doing more for you as you go. Sees on the free tier. Watches and diagnoses on advisor. Writes the fixes herself on operator.
Runs on every scan. Reads the evidence and gives you a plain-English summary: what she's fixing, what needs you, what's looking healthy. No score gauges. No wall of findings. Just the datafairy picking up the phone.
The deep-audit voice. Reaches across GA4, GTM, Google Ads, and Meta — pulls evidence, traces events, and ships a ranked, cited verdict. The same kind of work an analytics consultant does on a $5K retainer, in a few seconds, every time you ask.
Always running. Watches your site through a privacy-first pixel, catches drift the moment it happens, and writes GTM and GA4 fixes with one-click approval. Operates measurement now; operates the automation itself, soon.
Four layers feed every modern ad campaign.
A customer can be clean at one layer and broken at another. We don't roll them up — we operate each one, then connect the dots.
On-site signal
GA4, GTM, dataLayer, Pixels firing in the browser. What the algorithms see from real user behavior. We watch every event and verify it lands clean.
Ad-platform signal
Google Ads, Meta, TikTok each have their own measurement surface — independent of GA4. Conversion actions, Pixel + CAPI, Events API. We audit each platform directly via its own API.
Offline signal
Your CRM, POS, and warehouse — the systems that feed Offline Conversion Imports and audience syncs. PII never leaves your environment. Matching happens in clean rooms.
Automation (DMO)
Once the signal is honest, the natural arc is up the stack: bid strategy selection, value rules, audience activation, creative rotation. Per-platform operation of the automation itself, with human-in-the-loop approval.
What the datafairy actually says about a real site.
Plain-English summary, evidence-cited findings, automation impact estimated for every gap. No wall of warnings.
Top findings
GTM and a direct gtag.js call overlap on core templates, inflating sessions and distorting audience segments. I'll stage a GTM change that removes the gtag pageview — you'll get one-click approval before it ships.
The "Lead — Demo Request" conversion action hasn't received new offline uploads in 9 days. Either your CRM → OCI sync is broken, or no demos are happening — but the API can't tell which. Reconnect Google Ads or check your warehouse pipeline.
Three modes. Pick the one that sounds like you.
The datafairy adapts to where you are. Same agent, different verbosity, different defaults. Each mode aligns to a tier — but you can sit on any tier in any mode.
"I'm setting up tracking from scratch."
You're standing up GA4, GTM, and Google Ads for the first time. The datafairy walks you through the setup, names what's missing, and gives you copy-paste fixes. No jargon. No shame.

You inherited a stack. Some events look clean, others look weird, and the conversion numbers don't match across platforms. The datafairy audits dataLayer vs. GA4 vs. ad platforms, names the drift, and pages you when something breaks.

You know what good looks like. You don't have time to babysit the stack. fairy godmother runs continuously through a privacy-first pixel, catches drift the moment it happens, and writes the GTM fixes with one-click approval.
