The Tracking Problem Nobody Talks About

Your ad platforms are optimizing on incomplete data. Every missed conversion makes your campaigns dumber.

7 days

Safari ITP limits third-party cookies. Your Google click IDs expire before most B2B sales cycles even begin.

30–50%

Conversion data lost to browser privacy features, ad blockers, and consent friction. Your ROAS metrics are lying to you.

The amount ad platforms will refund you for the conversions they never saw. Garbage in, garbage out.

Five Steps to Complete Conversion Data

One line of code. Configure everything from the dashboard.

Capture

User submits a form or triggers a dataLayer event. Bytek Tag detects identity signals automatically.

Hash

Email and phone are normalized and SHA-256 hashed client-side. Raw PII never leaves the browser.

Enrich

User profiles from BigQuery are synced to localStorage. CRM data, segments, scores — available on every event.

Distribute

Hashed identity + enrichment data feeds Enhanced Conversions and Events APIs across 19 platforms.

Persist

First-party CNAME cookies survive 90 days. Server-side CAPI bypasses browser restrictions.

Enhanced Conversions Without the Complexity

Bytek Tag handles the hard part: capturing PII, hashing it, and feeding it to every platform in the right format. You just configure — zero code.

Enhanced Conversions, Made Easy

Google Enhanced Conversions, Meta Advanced Matching, TikTok Click ID matching, LinkedIn Insight — all require hashed PII. Bytek Tag captures emails and phones automatically, normalizes and SHA-256 hashes them client-side, and feeds every platform simultaneously. No manual implementation per platform. No PII on your servers.

Set up once • Works on all 19 platforms • Zero PII risk

User Profile Enrichment (BPP)

After identity resolution, Bytek syncs user profiles from your BigQuery People Platform. CRM data, purchase history, lead scores, customer segments — all persisted in the visitor's localStorage and available as @variables in any tag. Enrich every conversion event with the data that matters.

BigQuery → localStorage • Available on every event • No server round-trip

Server-Side CAPI Forwarding

Meta Conversions API, TikTok Events API, LinkedIn CAPI, Google Offline Conversions — all forwarded server-side from your first-party endpoint. Bypasses ad blockers, improves match rates, and deduplicates with client-side events automatically.

Server-side • First-party • No JS overhead

400-Day First-Party Cookies

Custom CNAME hostname + server-set HTTP-only cookies = up to 400 days of identity persistence. Safari ITP 7-day limit? Irrelevant. Click IDs (gclid, fbclid, ttclid) persist for the full attribution window.

Privacy-Centric PII Tracking

Your marketing team needs PII for conversions. Your legal team needs privacy compliance. Bytek gives you both: emails and phones are captured and hashed in the browser before any network call. Raw PII never reaches any server — yours or ours. GDPR cascade delete built-in.

SHA-256 client-side • No PII in transit • TCF v2.2 consent

19 Platforms, One Dashboard

GTM-like workflow: tags, triggers, @variables, consent categories, draft/publish versioning. Configure Google Ads, Meta, TikTok, LinkedIn, and 15 more platforms from a single admin panel. Real-time analytics to see exactly what fires and when.

Google Tag Gateway

Serve Google scripts (GA4, Google Ads, GTM) from your first-party domain. One click to enable — Bytek acts as a compliant GTG proxy. Ad blockers can't block what looks like your own domain. Google-certified implementation.

First-party Google tags • Ad blocker bypass • Zero CDN setup

Cookie Keeper

Server-set HTTP-only cookies survive Safari ITP's 7-day cap — up to 400 days. When a visitor returns after weeks, their identity persists. Automatic cross-session linking with prev_aid for zero-gap attribution.

HTTP-only • 400-day TTL • ITP-proof

Ad Blocker Detection

Know exactly how many visitors have ad blockers active and which platforms are affected. Bytek's first-party beacon always gets through — so your data stays complete even when Meta or Google pixels are blocked.

Real-time detection • Per-platform breakdown • First-party resilient
