Tag Your Ad URLs
Generate a pre-tagged URL for your ads. This links spend data to traffic behavior — no API needed.

Pick your ad platform. The builder fills in the correct tracking parameters automatically. Paste the generated URL into your ad's destination field.

Meta tip: {{campaign.name}} and {{ad.id}} are Meta dynamic parameters — Meta fills them in automatically on every click. Paste this URL directly into the ad's destination field in Ads Manager.

Install the Tracking Pixel
One line of code. Goes in the <head> of every page you advertise to. Takes under 2 minutes.
Where does it go?

Think of your website like a human body

Website HEAD and BODY structure diagram

Your website has a HEAD (invisible setup info) and a BODY (what visitors see). The pixel goes in the HEAD.

HEAD The invisible setup zone
Contains the title, fonts, and tracking scripts. Visitors never see this — it runs silently in the background.
BODY What visitors see
Your text, images, buttons — everything on the page. The pixel does NOT go here.
The pixel goes in the HEAD
Just before the </head> closing tag. It loads silently and won't change anything visitors see.

Here's what it looks like in a code editor:

The orange highlighted line is where your pixel code goes — right inside <head>, before the closing tag.

Your pixel code
<script async src="https://adintellx.replit.app/static/pcdf-pixel.js" data-pixel-id="USER_PIXEL_ID" ></script>
The async attribute means this tag will not slow your page. It loads in the background and does not block any content from appearing.
Where is your landing page built? Pick one.

6 Behavioral Signals — Captured Automatically
Each signal targets a different dimension of traffic quality degradation.
Time to First Interaction
Bots cluster at <100ms or never interact. Real humans take 1–8 seconds.
Scroll Velocity & Inflections
Bot scrolling is linear and fast. Humans slow down, reverse, and pause.
Active vs. Background Dwell
Low-quality inventory routes clicks to background tabs — users never view your page.
Rage Clicks
Frustrated users clicking rapidly signal mismatched ad-to-page targeting.
Largest Contentful Paint
Isolates inventory degradation from pure page-performance problems.
Input Focus Latency
Bots never focus form fields. Human latency reveals genuine interest level.
