Your ROAS is a lie. Every platform is claiming the same sale.
When a customer clicks a Facebook ad, then a Google ad, then buys — both platforms claim 100% of the revenue. Your dashboards show double the conversions that actually happened. Your budget decisions are based on fiction.
The double-counting problem is costing you money
Every ad platform runs its own attribution model in isolation. None of them know about the others. The result: wildly inflated conversion counts and ROAS figures that make every channel look like a winner.

A typical customer journey
Result without Signal: Google claims the full sale. Meta claims the full sale. TikTok claims the full sale. Your reports show 3 conversions for 1 actual order.
Signal sits between the conversion and every vendor API
Because Signal delivers conversions server-side, it controls exactly which platforms receive the event and what value they see. Attribution is not a report you read after the fact — it is a decision made in real-time before data leaves your infrastructure.
Track
Click IDs from every ad platform are automatically captured and stored as first-party cookies. gclid, fbclid, ttclid, msclkid, and more — all with full timestamp data.
Attribute
When a conversion fires, Signal evaluates the full touchpoint history and applies your chosen attribution model. Credit is calculated for each platform before any data is sent anywhere.
Deliver
Only credited platforms receive the conversion event. Each gets the correct attributed value — not the full order total. Platforms with zero credit receive nothing. No more phantom conversions.

Five attribution models, configured per pipeline
Choose the model that matches your business. Apply different models to different conversion events — time decay for purchases, last click for lead gen, position based for high-consideration products.
Last Click
Full credit to the final touchpoint before conversion. The industry default — simple, defensible, and easy to audit.
Best for: Teams migrating from platform-native attribution who want a clean baseline.
First Click
Full credit to the touchpoint that initiated the journey. Rewards the channel that created awareness.
Best for: Brand-building campaigns where discovery matters more than the final nudge.
Linear
Equal credit to every touchpoint in the path. No channel is overvalued, none is invisible.
Best for: Balanced reporting where every channel contribution should be acknowledged.
Time Decay
Credit weighted toward more recent touchpoints. The closer to conversion, the larger the share.
Best for: Performance teams optimising for lower-funnel efficiency.
Position Based
40% to first touch, 40% to last touch, 20% split across the middle. Values both discovery and closing.
Best for: Full-funnel strategies that need to credit awareness and conversion equally.
Custom Rules
Set vendor-specific caps, minimum credit thresholds, or custom weighting logic. Need Google to receive no more than 50% credit? Need a minimum £5 threshold before a platform receives a conversion? Configure it per pipeline.
Best for: Teams with specific business rules around vendor billing or partnerships.
Attribution tools tell you what happened. Signal changes what happens.
Triple Whale, Northbeam, Rockerbox, and others give you a dashboard with their view of attribution. But the conversion data sent to Google, Meta, and TikTok remains unchanged — every platform still receives the full value. The double-counting continues.
Attribution tools report. Signal acts.
Other platforms show you a dashboard. Signal controls what actually gets delivered to each vendor API. Attribution is enforced, not just observed.
No extra scripts. No extra cost.
Attribution runs inside Signal's processing pipeline. No additional JavaScript, no third-party pixels, no separate SaaS subscription.
Works with every vendor, automatically.
Click IDs from Google, Meta, TikTok, LinkedIn, Pinterest, Snapchat, and Microsoft are captured and stored as first-party cookies. Attribution decisions use the data Signal already collects.
Complete click ID lineage.
Every touchpoint is recorded with the exact click ID, timestamp, and source. You can audit exactly why a conversion was attributed to a specific platform.

Automatic click ID tracking from every ad platform
Signal captures every click ID as a first-party server-set cookie the moment a user arrives from a paid ad. These persist for the full attribution window — immune to ITP, ad blockers, and cookie clearing.

All click IDs are stored as server-set first-party cookies with 400-day expiry, making them fully exempt from Safari's ITP restrictions. The complete touchpoint history is available for attribution decisions throughout the entire attribution window.
Fine-grained control over every vendor
Attribution is configured per pipeline. Different conversion events can use different models, and vendor-specific rules let you handle edge cases without compromising the overall model.
Vendor credit caps
Limit the maximum credit percentage any single platform can receive. Prevent Google from absorbing 90% of credit in brand-search-heavy journeys where other channels did the awareness work.
Minimum value thresholds
Set a minimum conversion value below which a platform does not receive the event at all. If TikTok's attributed share of a £50 order is £2.40, suppress delivery entirely rather than polluting the platform's optimisation with micro-conversions.
Per-event model selection
Use time decay for high-value purchases, last click for lead forms, and position based for subscription sign-ups. Each pipeline defines its own attribution model independently.
