One Embed Script
The CRO9 embed script is a single tag, under 15KB, that you paste once into your site to start capturing behavioral signals — it needs no tag manager project, no SDK and no framework support.
Analytics projects usually die at installation. A tool needs a tag manager, a developer, a sprint, and a QA pass — and by the time it is scheduled, the reason for installing it has moved on.
CRO9 is one line. Paste it before the closing head tag and data starts arriving on the next pageview.
Why analytics installs stall
The technical work is usually small; the coordination is not. Access, approvals, a developer with capacity, and a release window turn a five-minute job into a six-week one — and every week of delay is behavioral data that cannot be recovered later.
- Tag manager access sits with someone else
- A developer ticket has to be scheduled
- Heavy scripts get pushed back on performance grounds
- Data is not backfillable — every week of delay is gone permanently
How to install CRO9 on any site
- 01
Create a site
Add your domain in CRO9 and you get a tracking key immediately.
- 02
Paste one line
Drop the script tag before the closing head tag. That is the entire install.
- 03
Load a page
Visit your site once and the dashboard confirms events are arriving.
- 04
Leave it alone
No maintenance. New pages are covered automatically because the script is site-wide.
What you get
Under 15KB
Small enough that performance is not an argument against installing it.
Asynchronous
Does not block rendering, so it costs nothing perceptible in load time.
Platform agnostic
WordPress, Shopify, Webflow, Squarespace, Next.js, a hand-built site — all the same one line.
Covers new pages automatically
Publish a page and it is tracked. There is no per-page setup.

Frequently asked questions
How do I install CRO9?
Add your site in CRO9 to get a tracking key, then paste a single script tag before the closing head tag on your site. Data appears on the next pageview.
Will it slow my site down?
The script is under 15KB and loads asynchronously, so it does not block rendering.
Does it work with Google Tag Manager?
It can be deployed through a tag manager if you already use one, but it does not require it — which is usually what unblocks the install.
What platforms are supported?
Any platform that lets you add a script tag: WordPress, Shopify, Webflow, Squarespace, Next.js, or a custom build.
Do I need to add it to every page?
No. Install it site-wide once — usually in your theme or root layout — and every page, including future ones, is covered.
