Campaign Version
Staff float between sites with no real-time view of who's working where. Coverage gaps show up mid-week. We build scheduling platforms that show every clinic's team in one place.

Compliance evidence is scattered across spreadsheets and email, so every audit is a scramble. We build one platform that centralizes compliance data and flags gaps before auditors do.

You sell on Amazon, eBay, and Shopify, but stock only updates on one. Overselling means refunds and fulfillment delays. One integrated platform gives you real-time stock sync with no manual updates.

How It Works
Set up in minutes. Prove the lift in days.
Add the Lens snippet
Paste one short snippet into your site's <head>. Works with any platform: WordPress, Webflow, Shopify, custom code. That's the only technical step.
We scan your pages
Lens finds every text section on the pages you choose — headlines, body copy, CTAs, captions. You pick which ones to personalize and which to leave alone.
Create a campaign
Paste in your ad URL — Lens reads the UTM parameters and figures out the audience. Or describe it yourself. Either way, you go from ad link to campaign copy in seconds.
Choose your copy
Lens generates two options for every section, tuned to your campaign audience. Pick one, edit it, write your own, or keep the original. Nothing goes live without your say-so.
Publish and measure
Hit publish. Visitors from that campaign see your chosen copy instantly. Set a holdback rate so a percentage always see the original — then watch the conversion data come in and know exactly what's driving results.
Built-In Proof
Don't guess. Measure.
Every campaign runs a controlled experiment. You set the holdback rate, Lens tracks the conversions, and your dashboard shows exactly what's lifting — and by how much.

FAQ
Questions, answered.
How do I add the Lens script tag to my site?
Lens starts with one short snippet in your site's <head>. Copy it from the dashboard and paste it where your platform takes custom code: a theme setting in WordPress or Shopify, the custom code panel in Webflow, a Custom HTML tag in Google Tag Manager, or your template if you write your own HTML. That is the only technical step.
Lens then checks the live page, confirms the site ID and waits for the first request. When it arrives, the dashboard tells you the site is live.
Who writes the copy, and does anything go live without my approval?
For every block you allowed, Lens writes two options aimed at the audience you described. Keep one, edit it, write your own or keep the original. Regenerate an option if neither is close.
Nothing is published until you publish it. The copy you approve is the only copy a campaign visitor can see.
What do visitors who did not come from an ad see?
Your original page. A visitor who arrives without UTMs is never matched, so your organic traffic always sees the original. Search crawlers arrive the same way, so they see the original too.
What is a holdback, and why not just compare before and after?
The usual way to judge a copy change is to compare this month with last month. That comparison mixes your change with everything else that moved: budgets, seasons, a competitor going quiet, a sale ending.
A holdback removes most of that. Lens assigns each campaign visitor to one of two groups when they first arrive. The control group keeps seeing the original page. Both groups arrive from the same ads at the same time, so the copy is the main thing that differs between them.
You set the holdback rate for the site, anywhere from 0 to 20% of campaign visitors. A bigger control group gives you a steadier baseline sooner. A smaller one shows more visitors the campaign copy.
Which conversions does Lens count?
Lens counts conversions on your page rather than trusting each ad platform's own numbers, so both groups are measured with the same ruler. It recognizes common conversions without setup: form submissions, clicks on calls to action and clicks through to tools such as Calendly, HubSpot or Intercom. For anything else, one call does it:

Notes on message match and measurement
When swapping a keyword isn't enough
Sometimes you need a different word. Sometimes the whole headline needs a different point.
Does every ad group really need its own landing page?
Eight ad groups. Eight landing pages. Then your pricing changes. There is a simpler way to keep the message matched.
The ad found the right person. The page made them start over.
Before you rewrite the ads, check what happens after the click.
You target the right people.
Make sure they hit the right page.
Give every ad campaign its own version of your site. Track the conversions. Prove the lift. Start in five minutes.
