Your Funnel Crosses Domains. Your Attribution Shouldn't Break.
Trusted by thousands of companies globally
Every Domain Hop Costs You Data
Your customer clicks a Facebook ad. Lands on your landing page. Clicks through to checkout on Shopify. Buys.
Facebook sees the click. Facebook sees... nothing else. The cookie stayed on your landing page. Shopify is a different domain. The pixel fires, but Facebook can't connect it to the original click. So that $200 sale? Facebook thinks the ad didn't work. Its AI learns the wrong lesson and bids less on audiences that actually convert.
Now multiply that by every sale through third-party checkouts, affiliate networks, and booking tools. You're bleeding attribution at every domain boundary — and paying for it in wasted ad spend.
One Journey, Every Domain, Full Credit
Stitch User Identity
Cookies can't cross domains. AnyTrack connects first-party data server-side — so the customer who clicked your ad is the same one who bought on Shopify.
Keep Every UTM
Campaign data vanishes at domain hops. AnyTrack preserves source, medium, and campaign through redirects, handoffs, and external checkouts.
Feed Complete Data
Ad platforms optimize on what they see. Send them the full journey via Conversion APIs — so their AI learns which clicks actually drive revenue.

Cross Domain Capabilities
<>
First-Party Data
Capture user signals with first-party cookies on each domain. AnyTrack unifies them server-side — no third-party cookies required.
<>
Server Resolution
Identity matching happens on AnyTrack servers, not in browsers. Safari, Firefox, and ad blockers have nothing to block.
<>
UTM Persistence
Source, medium, campaign, content, term — all survive domain transitions, redirects, and checkout handoffs. No more "direct/none" mystery traffic.
<>
CAPI Delivery
Complete journey data flows to Facebook CAPI, Google Enhanced Conversions, and TikTok Events API. Full attribution, not fragments.
<>
Subdomain Support
Blog to shop to checkout — www.site.com to shop.site.com to pay.site.com. One continuous journey, automatically linked.
<>
External Domains
Attribute conversions on affiliate networks, SaaS checkouts, and booking platforms back to your campaigns. Their domain, your attribution.
Cross Domain Tracking Questions
How It Works
Browsers treat each domain as a separate entity. When someone clicks your ad and lands on landing-page.com, the browser sets a cookie there. When they click through to checkout.shopify.com, that cookie stays behind — different domain, fresh start.
Ad platforms see two separate sessions instead of one journey. The click happens on one domain, the purchase on another, and nothing connects them. Facebook thinks the ad didn't convert. You think the campaign failed. The customer who just paid you $200 disappears from your attribution.
AnyTrack combines client-side and server-side tracking. On each domain, we collect first-party data — click IDs, UTM parameters, session identifiers. Our servers stitch these signals together using deterministic matching to rebuild the complete journey.
When a conversion fires on the final domain, we match it back to the original click. Then we send the complete path to ad platforms via Conversion APIs — so Facebook learns that this specific ad drove that specific sale, even across three different domains.
Not usually. For affiliate networks, SaaS checkouts, and third-party booking tools, AnyTrack receives conversion data via server-side integrations — postbacks, webhooks, native connections. You only add our tag to domains you control. The external platforms send us the conversion; we match it to the original click.
Without cross-domain tracking, UTMs vanish at every boundary. Customer clicks your ad with utm_source=facebook, lands on your page, clicks to checkout — and suddenly it's "direct/none." Your campaign disappears from attribution.
AnyTrack captures UTM parameters on the first touchpoint and persists them server-side. When the conversion fires on a different domain, we attach the original campaign data. Facebook gets full attribution; you get accurate ROAS by campaign.
Setup & Compatibility
Most setups take 15-30 minutes. Add the AnyTrack tag to your owned domains, connect your conversion sources (Shopify, affiliate networks, CRMs), and link your ad platforms. Our integrations handle the server-side connections — no custom development required.
Any domain where you can add our JavaScript tag or receive server-side conversion data. That includes Shopify, WooCommerce, ClickFunnels, Unbounce, affiliate networks (ClickBank, CJ, ShareASale), checkout tools (ThriveCart, SamCart), CRMs (HubSpot, GoHighLevel), and 300+ more integrations.
Yes — even messy ones. Affiliate link cloaking, multi-step redirect chains, URL shorteners. AnyTrack preserves tracking data through every hop because we're capturing signals server-side, not relying on cookies to survive the journey.
Both work seamlessly. Traffic from www.site.com to shop.site.com to checkout.site.com? One journey. Traffic from site.com to completely-different-domain.com? Still one journey. AnyTrack maintains attribution continuity regardless of domain structure.
Privacy & Accuracy
Yes. AnyTrack uses first-party data collection and server-side processing — both aligned with GDPR, CCPA, and other privacy frameworks. We don't rely on third-party cookies or fingerprinting techniques that regulators have flagged. You control what data flows where based on user consent.
With our tag on owned domains plus server-side integrations for conversion sources, most customers see 85-95% attribution coverage. Compare that to cookie-only tracking in multi-domain funnels: typically 40-60% — meaning you're making optimization decisions on half your data.
Minimally. iOS restrictions hit client-side tracking hardest — pixels, cookies, app-to-web handoffs. AnyTrack captures conversions server-side from backend systems (eCommerce platforms, affiliate networks, CRMs), not browser pixels. The conversion happens regardless of iOS settings; we capture it where Apple can't block it.
Ad platforms optimize based on conversion signals. When you send complete journey data — including conversions that happen on external domains — their algorithms learn which clicks lead to sales, not just which clicks lead to landing page visits. More signal in, better targeting out, lower CPA.
