Tracking

Cross-domain tracking that keeps one visitor across every site

Your site, your funnel builder, your checkout and your booking page can all live on different domains. The visitor stays the same.

  • Flat monthly price, no revenue tax
  • No annual contract
  • Tracking starts the minute the snippet is live

Cookies don't cross domains. When a visitor moves from yoursite.com to a checkout on another domain, most tools see two people and lose the ad click that started it all.

List all your domains in BrainyMetrics and tracko.js decorates links, forms and window.open calls to them with a short-lived parameter, so the visitor id travels with the click. Embedded iframes on your allowed domains receive the parent page's visitor id automatically. Google's _gl cross-domain linker is read too.

The problem

What it costs to go without cross-domain tracking

Your marketing site, funnel pages and checkout often live on different domains. Each hop can reset the visitor, so the buyer who arrived from a Meta ad shows up at checkout as a direct visit with no history.

That one break is enough to strip credit from the ad that started the sale and hand it to nobody. On funnels with several domains, it can erase most of your paid attribution.

What you get with Cross-domain tracking

Automatic link decoration

Links, forms and window.open to your other domains carry the visitor across.

Iframe hand-off

Embedded forms and checkouts on your domains get the parent's visitor id.

Works with GA's linker

Click ids carried in Google's _gl parameter are captured.

Manual control

tracko.decorate(url) adds the parameter to links you build yourself.

Why BrainyMetrics

Marketing without guesswork

What changes when every lead, call and sale is tied back to the ad that started it.

Meta, Google and TikTok each claim the same sale, so platform totals add up to more than your bank account.
Each sale is counted once, from your own checkout data, and reconciled against what each platform claims.
Analytics gives the last click all the credit, so the ads that start journeys look like they lose money.
Seven attribution models are computed for every conversion, so you can compare first click, last click and everything between.
Phone calls and booked calls are a black box. You know they happened, not which ad caused them.
Calls and bookings are matched to the visitor's session and the ad behind it, then tracked through qualified and closed.
Ad blockers, Safari and cross-domain checkouts quietly break your data.
A first-party tracking subdomain, server-set cookies and cross-domain linking keep journeys intact.
Spend lives in one tab, revenue in another, and ROAS is a spreadsheet you rebuild every Monday.
Spend syncs hourly and sits next to attributed revenue, so ROAS, CPA and profit are on every row, down to the ad.
Ad algorithms optimise on the few conversions their pixel happens to see.
Real purchases and leads are sent back to the ad platforms' conversion APIs, deduplicated against the pixel.

Stop guessing which marketing pays.

Frequently asked questions

Common questions about Cross-domain tracking, setup and pricing.

The fastest answer is your own data

Create an account, install the snippet and see how BrainyMetrics handles your real traffic.

Get started
What do I need to set up?

Install the snippet on every domain and list all of them under Settings → General.

Is the parameter permanent?

No. It is short-lived and only used to hand the visitor over on the next page.

How long does setup take?

The basics take minutes: paste the snippet, connect your checkout or funnel builder, and connect your ad accounts. The setup checklist in your dashboard ticks each step off as data arrives, so you always know what's left.

Do I need a developer?

Usually not. The snippet can go in through Google Tag Manager, WordPress or your funnel builder's tracking code settings, and most revenue sources connect with a click or a webhook URL you paste. The developer guide covers the JavaScript and server API if you do have a developer.

Does the price go up as I grow?

No. Plans are a flat monthly or yearly price. We never bill a percentage of revenue or ad spend, and you can switch, pause or cancel from the Billing page without a call.

Does tracking stop if I hit a plan limit?

No. Plans limit dashboard modules and things like integrations or workspaces; tracko.js, webhooks and syncs keep collecting data, so nothing is lost if you upgrade later.

Is it privacy friendly?

Yes. BrainyMetrics supports consent modes, works with your consent banner, respects Global Privacy Control and handles sensitive form fields strictly. Data is first-party: it belongs to your workspace, not an ad network.
