Ad revenue depends on data quality. Data quality depends on delivery.
When 30% of your audience blocks analytics tags, your match rates drop, your CPMs fall, and your programmatic yield suffers. Datafly Signal delivers engagement data server-side — invisible to ad blockers and orders of magnitude faster than client-side tags.
The real cost of client-side tags for publishers
Every vendor tag on your pages costs you in revenue, performance, and regulatory exposure. The cumulative effect compounds across millions of daily pageviews.
Revenue leakage
Missing pageview and engagement events mean lower match rates with SSPs and DSPs. Lower match rates mean lower CPMs. You are leaving money on the table with every ad impression that cannot be properly attributed.
Performance death spiral
30 vendor tags add 2-5 seconds to page load. Slow pages increase bounce rate, reduce pages-per-session, and lower total impressions. Fewer impressions compound into significant revenue loss across millions of sessions.
Regulatory exposure
DMA, GDPR, ePrivacy — each vendor tag runs third-party JavaScript with full DOM access across 30+ scripts. Managing consent, data flows, and compliance across all of them is a governance nightmare at scale.
Server-side delivery for publishers
Move vendor delivery off the page and onto the server. Your readers get faster pages. Your ad stack gets better data. Your compliance team gets control.
Ad-blocker resistant
Events flow through your own subdomain via first-party DNS. Ad blockers that filter third-party requests never see the data leaving. Your analytics capture the full audience, not just the unblocked portion.
Page speed recovery
Replace 800KB+ of vendor JavaScript with a single 4.2KB collector. Pages load faster, bounce rates drop, pages-per-session increase, and your total impression volume grows.
Higher match rates
Server-generated vendor IDs (_ga,_fbp) with 400-day server-set cookies. More complete user identity means higher match rates with SSPs and better programmatic yield.
Programmatic data quality
Schema-validated events with standardised field names and enforced data types. Clean, consistent data feeds into your DMP, data warehouse, and ad server — improving audience segmentation and targeting accuracy.
Measure what readers actually do
Track scroll depth, time on page, article completion, and content engagement with a single event that feeds both your analytics platform and your data warehouse simultaneously.
Pipeline configs define the transformation once. Every vendor receives exactly the fields they need in exactly the format they expect — no per-integration custom code.
- Scroll depth tracking at 25%, 50%, 75%, and 100%
- Time-on-page with active reading detection
- Article completion events for paywall and subscription optimisation
- Simultaneous delivery to analytics and data warehouse

Media companies run multiple brands, sites, and apps. The Identity Hub links a reader's sessions across all your properties into a single unified profile — even in Safari, even across domains.
Identity Hub Features
- AES-256-GCM encrypted tokens with 60-second TTL and single-use nonces
- Works in Safari — server-side resolution bypasses ITP restrictions
- Unified reader profiles across all your domains and properties
- 400-day server-set cookies for persistent cross-session identity
- Consent-gated — identity resolution only occurs with user consent

Consent enforcement at publisher scale
With millions of daily pageviews across multiple properties and jurisdictions, consent management cannot be an afterthought. Datafly Signal enforces consent at two layers — at collection in the browser and again at delivery on the server.
Even if a CMP misconfiguration allows an event through, the server-side layer catches it before data reaches any vendor the user has not consented to.
