The Bidding Engine Your Ad Accounts Don’t Have.
Google and Meta already run world-class bidding algorithms. They just bid on whatever number your tracking hands them. Lux Signal is the bidding engine that owns that number — deciding what every conversion is really worth, which ones shouldn’t count at all, and who you should stop bidding on entirely — then feeds it back through server-side conversion APIs so the platforms bid on your model instead of their guess.
Built by Lux Marketing — managing $100K+/mo in paid media across 12+ industries.
Every Bidding Algorithm Is Only As Good As the Number It Bids On
Google and Meta bid brilliantly. They just bid on a number nobody has looked at since the day the tracking was installed.
A form fill, a free trial, a $400 order and a $120 order all report as conversions worth whatever your tag says. The bidding algorithm can’t tell them apart, so it bids as if they’re the same.
The platform sees the checkout. It never sees the refund, the churn, the lead that never closed, or the customer who came back four more times. It bids on the fraction of value it can observe.
It was set once by whoever installed the tracking and never revisited — and each platform bids on its own siloed version of it. The highest-leverage input in your account is running unowned, on autopilot.
How Lux Signal Works
It doesn’t replace Smart Bidding or touch your budgets. It owns the signal the bidding algorithms run on.
We pull conversions, margins, refunds, pipeline and LTV from your warehouse and CRM — the clean data your Foundation already collects.
Proprietary models assign each conversion a real worth — predicted profit, lifetime value, lead quality — combining your own value rules with enriched third-party data the bidding algorithms never see.
Those corrected values flow back to Google and Meta through server-side conversion APIs — the same rails your Clean Data Foundation runs on. No platform API approvals, no risk to your account.
Smart Bidding keeps doing the bidding, at the platform’s full speed and scale — but now it’s bidding on your definition of value, across both channels.
Margins, LTV, pipeline
Value + quality per conversion
CAPI + Enhanced Conv.
Bid on your model
What a Bidding Engine Actually Does
Four jobs no ad platform will ever do for you, because the data they need lives inside your business.
Predicted profit, lifetime value, pipeline value — whichever definition fits your business. The bidding then chases the customers worth having instead of the ones that look biggest at checkout.
Every lead and conversion is scored before it ever reaches the platform, so junk conversions stop training the bidding algorithm to go find more of them.
Existing customers, low-fit segments, accounts that will never close. They’re sent through at near-zero value, so the platforms’ own bidding stops chasing them.
Anomaly detection, tracking-break alerts, value caps and guardrails — built to catch a broken tag or a freak order before it distorts a week of bidding.
“Valuable” Means Something Different in Every Business
The engine doesn’t impose one definition of value. It bids on yours.
- Bid on contribution margin, not order value
- Repeat-purchase and cohort LTV, not first order
- Discount conversions by refund and return probability
- Bid harder on the first orders that become second orders
- Lead quality score sent as the conversion value
- Closed-won revenue imported back from the CRM
- Suppress tire-kickers, existing clients and bad-fit geos
- Bid on booked revenue, not form fills
- Churn-discounted predicted LTV, not signup count
- Trial-to-paid quality scoring at the point of conversion
- Firmographic fit — company size, industry, role
- Bid on accounts that retain, not trials that register
Why It’s Different
Not another bid-management tool fighting the platforms for control. A bidding layer that makes their algorithms work your objective.
You define what a conversion is worth, and the platforms bid to that definition. The single input that decides where every dollar goes finally belongs to you.
One bidding model across Google and Meta, measured on blended after-margin return — the view no single platform will ever give you.
Value caps, rules, and anomaly protection. You tune the model and approve the logic — no bidding decision runs as a black box.
It never sets bids or moves budgets directly. It only corrects the values the bidding algorithms consume, so the platform’s own safeguards always stay in force.
Proprietary models combine your first-party data with enriched third-party signals the platforms can’t see. The richer the inputs, the bigger the bidding edge competitors can’t replicate.
No rip-and-replace. Keep tROAS, Max Conversion Value, or Performance Max — the engine just gives your existing bidding strategy a smarter target.
Inside the Engine
A hybrid of machine-learning models and a rules-and-guardrails layer, fed by your data and enriched with third-party signals. Here’s what’s under the hood of the bidding engine.
- Identity & match data (higher match rates, householding)
- Firmographic & B2B (company size, industry, revenue, role)
- Intent & behavioral signals (in-market audiences)
- Demographic & financial (geo, income, household value)
- Predicted lifetime value (pLTV), not just first purchase
- Lead & conversion quality scoring
- Refund & churn probability discounting
- Blended cross-platform attribution
- Anomaly detection & tracking-break alerts
- Audience suppression (exclude existing or low-fit buyers)
- Offline & CRM conversion import (closed revenue)
- Value caps, rules & guardrails you control
Runs on a Clean Data Foundation
Lux Signal is only as good as the data underneath it. Bidding on profit, LTV or lead quality means the engine needs server-side tracking, conversion APIs, and that data wired into one place. That’s exactly what our Clean Data Foundation builds. If your tracking and data are already solid, we plug straight in. If they’re not, the Foundation is step one — and the reason your bidding will outperform anything your competitors can run.
