A CRO agent that keeps
testing after launch day
A landing page usually gets tested once, at launch, and then left alone for a year because nobody has time to keep generating and checking variants. We build an agent that proposes new copy and layout tests from what your analytics actually show people doing, and tells you which version really moved conversion.
The role today
A landing page gets built, launched, and then mostly left alone, because testing it properly means someone has to notice where visitors are actually dropping off, write a hypothesis, build a variant, run it long enough to mean something, and read the result correctly, a cycle that competes with every other task on a growth team’s list. Most pages that do get revisited get changed on a hunch rather than on a read of where people actually leave, which means the fix sometimes targets the wrong part of the page entirely while the real drop-off point goes untouched for another year. A page left untested for a year is not neutral, it is a page actively losing ground, since competitors keep testing and improving their own funnels in the same period, and a conversion rate that felt competitive at launch quietly becomes mediocre relative to where the market has moved by the time anyone circles back to check.
What the agent takes over
The agent reads your analytics to find exactly where visitors drop off, not a vague “conversion is low” but the specific step, a pricing section, a form field, a loading delay, and proposes copy and layout variants targeted at that point rather than a generic redesign. It runs the test with a proper significance check accounting for sample size and duration, flags an early read as premature instead of calling it, and once a result is real, reports which version won, by how much, and what that likely means. Mobile and desktop traffic get read separately where volume allows, since a fix that helps one often does nothing or even hurts the other.
The test log doubles as institutional memory for the page: a variant that was already tried and lost six months ago does not get proposed again as if it were a fresh idea, and a pattern that keeps winning across several tests, shorter forms, social proof placed higher, gets surfaced as a principle worth applying to other pages in your funnel rather than staying a one-off result nobody connects to the bigger picture.
What stays with humans
Deciding the page’s overall offer and positioning, approving a variant before it goes live to all traffic, and deciding how far to push a redesign stay with your team. The agent finds the drop-off and tests the fix correctly; people decide what the page is actually trying to sell.
Guards
A test is never called a winner before it reaches the sample size and duration needed for a reliable read, and that threshold is shown in every report rather than hidden behind a confident-looking headline number. Every variant and its result are logged, so a year of tests compounds into real knowledge about the page instead of repeating the same experiment. A kill switch reverts to the last approved version in one message. A new page or a new testing framework runs in a dry run, analyzed and proposed but not yet live-tested on real traffic, until the drop-off analysis is confirmed against what your team already knows about the page. If CRO moves in-house, we hand over the test log and the drop-off analysis, documented for your own team to continue.

FAQ
How much does a landing page cro agent cost?
From $2,400 for drop-off analysis, variant generation and significance testing on one key landing page, live in 3 to 4 weeks. Covering a full funnel across several pages usually runs from $4,000.
How long does it take to go live?
Three to four weeks: the first two analyze your actual traffic and drop-off points and draft the first round of variants, the rest runs and reads the test properly before reporting a winner.
Which channels and tools does it work with?
It works from whatever analytics you already have (GA4, a product analytics tool, or server-side event logs) and tests directly on your site or landing page builder, no separate testing platform required unless you already have one.
What if it gets something wrong?
The agent is built specifically against the common CRO mistake of calling a winner before the sample size supports it; it flags an early read as premature instead of reporting it as a result, and shows its confidence level on every call.
What about our data and security?
Your analytics and site access stay on your own accounts. We read traffic and conversion data to find drop-off points; nothing is shared outside your own tools.
