Tracking

Engagement analytics for every page and every traffic source

See how visitors from each ad actually engage: time actively on page, scroll depth, video progress and page speed.

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

Two ads with the same click-through rate can send very different visitors. Engagement tells you which traffic reads, watches and scrolls before the conversion data comes in.

tracko.js measures engaged time (visible and active), scroll depth and Core Web Vitals (LCP, CLS, INP, FCP, TTFB) on every page. Video starts, 25/50/75% and completions are tracked for HTML5, YouTube, Vimeo and Wistia. Mark any section with data-tracko-view to count how many visitors actually saw it.

The problem

What it costs to go without engagement analytics

Two ads can deliver the same number of clicks at the same cost, while one sends people who read, scroll and watch, and the other sends people who leave in three seconds. Click counts can't tell them apart.

Waiting for sales to show the difference takes time and money. Engagement data shows the quality of traffic within hours.

Why BrainyMetrics

Marketing without guesswork

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

Without BrainyMetrics

With BrainyMetrics

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 Engagement analytics, 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

Does it work on single-page apps?

Yes. History API route changes are page views, with time and scroll measured per route. Hash routing can be turned on.

Does it slow my site down?

The script loads asynchronously and never blocks rendering. Events are batched and sent in the background.

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.
