Weeks, not months

You spend real money getting people to your page, and most of them leave. Sometimes that’s the traffic, but just as often it’s the page - it’s where people decide whether to act. A fuzzy headline, a buried offer, a form with too many fields. Any one of them is enough to lose the click you paid for. We audit the page your ads point to, find what’s costing you conversions, and redesign it to fix that. Signal shows us what’s worked across the hundreds of pages we’ve optimized, so the calls we make come from evidence, not opinion.

The conversion process

You’re too close to your own page to see what it’s costing you.

So we look at it the way a first-time visitor does, and the way the data does. We find where people drop off, work out why, redesign to fix it, then test the new page against the old.

  1. 01

    Audit

    We go through your page the way a skeptical buyer would, line by line, then pressure-test our read against the data: where attention drops, where people hesitate, where they leave. After hundreds of teardowns, we know exactly which parts are costing you conversions.

  2. 02

    Diagnose

    Then we figure out why. Most pages lose for a few familiar reasons: the headline doesn’t land in seconds, the offer is buried, the objections go unanswered, or there’s just too much to click. We pinpoint which ones are yours.

  3. 03

    Redesign

    We rewrite and rebuild the page around what actually converts: a clear, specific headline, benefits over features, social proof where the decision happens, and one obvious next step. It ships ready to launch, not as a slide deck.

  4. 04

    Test & Scale

    We run the new page against the old one with real traffic and let the conversion rate settle it. What wins becomes your new baseline, and we keep testing from there.

What we work on

The handful of things that decide
whether a page converts.

Above the Fold

The first screen does about 90% of the work. We find your product’s real magic and pitch it in a headline people understand in seconds, because that first moment is the difference between a scroll and a bounce.

Conversion Copy

Clear beats clever. We write the page around the outcome the customer’s buying, not a list of features, and we answer the objections most pages leave hanging right where they come up.

Layout & Design

We don’t reinvent the page. Proven, practical layouts that point the eye at the one thing you want clicked. Your product and brand should be the unique part, not the layout.

Social Proof & Trust

Buyers trust other buyers more than they trust you. We place the right proof exactly where people decide to act, so trust turns into a click instead of second-guessing.

Product Detail Pages

For ecommerce and DTC, the product page is where the sale is won or lost, and it’s the most demanding page to get right. Specs, variants, reviews, shipping, and trust all compete for one add-to-cart. We rebuild it around the few things that actually drive the purchase, built to convert on mobile where most of these sales happen.

Speed & Mobile

Most pages are built on a desktop and fall apart on a phone. We design for mobile from the start, not as an afterthought, and cut the weight, because a page that loads slowly bounces before it ever gets the chance to convert.

A/B Testing

We test the new page against the old one with real traffic and let the conversion rate decide. The winner becomes your baseline, and we keep testing from there.

The challenge

Running Google Ads at modest returns with no way to scale. A previous agency had left messy infrastructure - overlapping keywords, shared budgets cannibalizing campaigns, and only two channels live.

What we did
  • Paid across Google, Meta, Bing, and LinkedIn
  • Rebuilt the campaign architecture from scratch
  • Keyword + intent segmentation
  • New ad copy and retargeting
  • Channel expansion + platform recovery
Results
  • ~4x increase in revenue from paid in 12 months
  • Expanded from 2 to 4 active channels
  • Hit the best-performing month in company history
Programs

Two ways to work together.

01

Page Audit

A senior teardown of the page you’re running now, with a prioritized list of fixes.

  • Where the page is losing people, and why
  • A prioritized list of fixes
  • Backed by our teardown library

Page Redesign

Everything in the audit, plus we rewrite and rebuild the page, ready to launch.

  • New copy, layout, and design
  • Built to convert, delivered ship-ready
  • One key page, end to end

Our Model

The agency model was never built for startups, let alone for the AI era. Ours is.

Senior startup-growth talent, a full-stack team, proprietary AI, and built-in distribution, brought together in one model the old agency never could.

FAQ

Questions, answered.

Everything teams ask before a redesign. Still stuck? We’re one conversation away.

Let's talk

Traditional agencies aren’t built for startups. They’re built for big clients and their own margin, which means an army of junior account managers, standardized playbooks, and bloated meeting cycles. Worse, they’re built to sell, not deliver. You meet their polished executives during the sales process, hear all about the awards they’ve won and how elite their team is, and sign. Then, unbeknownst to you, you’re handed to a junior team, shielded behind an account manager who’s really a salesperson in a strategist’s clothing. Meanwhile startups sit at the bottom of the priority list while the senior people stay on the bigger accounts.

Most agencies are wrapping the same off-the-shelf tools everyone else has, trained on the same public data, so they get the same average outputs. Signal is our own AI, trained on a decade of data no one else has from 7,000+ startups, our Growth Engine methodology, and a community of 110,000+ operators sharing what’s working directly from the front lines. It gives our strategists superpowers, helping them move faster and spot opportunities they’d never spot alone, while the highest-leverage work, the strategy and the hard problems, stays firmly with our people.

Just the pages that move the needle, usually the ones your ads and campaigns point to. This isn’t a rebrand or a ground-up rebuild. We focus on the highest-leverage pages and leave the rest of your site alone.

Either. We deliver the redesign ready to launch, either as dev-ready files your team can ship or built out by us. We’ll scope that on the first call based on your stack.

Two ways. Signal starts us from what’s already converted across the hundreds of pages we’ve worked on, so the redesign isn’t a guess. Then we A/B test the new page against your current one, so the conversion rate has the final say.

No. Plenty of clients run their own traffic and just want the page it lands on to convert better. It works on its own, and it works even better when the ad and the page are built to match.

Weeks, not months. An audit is quick, and a redesign moves fast because we work from proven patterns instead of starting from a blank canvas every time.

Your Growth Experiments Are Lying to You

Growth experiments should be your most powerful tool. But most teams run them wrong - optimizing for velocity over learning, testing the wrong variables, and declaring winners based on hope.
