CRO9
Self-optimizing landing pages. Living DOM mutations + 147 behavioral metrics + Multi-Armed Bandit testing.
A 15KB embed that turns any landing page into a self-optimizing one. Tracks 147 behavioral metrics, runs Multi-Armed Bandit experiments, and mutates content in real time based on what's converting.
CRO9 is the optimization layer behind every page RocketOpp ships. Every Living DOM rewrite, every PPC landing page, every SXO Growth client gets CRO9 on top. The mutation engine learns what converts and rewrites the page accordingly — no A/B-test setup, no traffic-split planning, no waiting for significance.
How CRO9 got built — and why.
Classic A/B testing is dead. By the time you have statistical significance on your headline test, the world has moved on, the campaign has ended, and most of your traffic saw the loser.
CRO9 takes the modern approach: Multi-Armed Bandit allocation. The engine sends more traffic to the winning variant in real time — every visitor benefits, no need to wait for "significance."
On top of MAB we layered Living DOM mutations: instead of pre-defined variants, the engine generates new variants automatically based on visitor behavior. Different headline for mobile vs desktop, different CTA for paid vs organic, different social-proof block by traffic source.
How agentic AI runs CRO9 on autopilot.
CRO9's mutation engine pulls from 0nMCP for content generation. New variants are Groq-generated, schema-validated, and shipped in real time.
The 147 behavioral metrics are stored in Supabase and reachable via 0nMCP tool calls — meaning AI agents can read CRO9 data and act on it (e.g. "if conversion rate on this page drops below 2%, generate three new variants").
CRO9 is what makes every other RocketOpp service compound. PPC sends traffic; SXO sends rankings; CRO9 makes sure the page that lands them converts.
What CRO9 actually does.
Six capabilities. Each one composes with the rest of the RocketOpp stack.
Living DOM mutations
Real-time content rewrites based on visitor behavior. Different headline for mobile, different CTA for paid traffic, different social-proof for industries.
147 behavioral metrics
Scroll depth, time-on-section, hover heatmaps, abandonment points, click-trail. Every signal CRO data scientists track, automatically.
Multi-Armed Bandit
Replaces A/B testing with allocation that learns. Winning variants get more traffic in real time — no waiting for significance.
<15KB embed
Drop a single script tag. No PageSpeed hit. No bloat. Works on any platform — WordPress, Webflow, Next.js, custom HTML.
AI variant generator
New copy + CTAs + layouts generated by Groq automatically. No more "we need to write more variants" — the engine writes them.

Frequently asked questions
The honest answers a buyer would want before booking a call.
What is CRO9?
+
A self-optimizing landing-page engine that runs as a 15KB JavaScript embed. Tracks 147 behavioral metrics, runs Multi-Armed Bandit experiments, and mutates content in real time based on what's converting.
How is this different from Optimizely or VWO?
+
Optimizely / VWO are A/B testing tools — you write variants manually and wait for significance. CRO9 generates variants automatically with Groq, allocates traffic with MAB, and rewrites content in real time. Smarter, faster, cheaper.
Will the embed slow my site down?
+
No. Under 15KB gzipped, async-loaded, runs after page paint. We measure PageSpeed before/after on every install — it's typically a 0-2 point delta.
What metrics does CRO9 track?
+
147 behavioral signals: scroll depth, time-on-section, hover heatmaps, abandonment points, click trails, form-field interaction, copy-paste events, and 140 more. All correlated with conversion.
Does it work with my platform?
+
Yes. WordPress, Webflow, Squarespace, Shopify, Next.js, custom HTML — anywhere you can drop a script tag.
How much does it cost?
+
Ignite is $29/mo, Amplify is $99/mo, Dominate is $299/mo. All plans include the full engine; tiers differ on traffic limits and seat count.
