Conversion rate optimization services for pages that carry paid traffic

You can cut cost per click by a third and still generate the same number of leads, because the bottleneck was never the auction. When the same person runs the ads and the page, nobody gets to blame the other one.

The Problem

Where paid traffic dies

The gap between a good click and a lost visitor.

Message match breaks at the click

The ad promises one specific thing and the page opens with a generic homepage headline. The visitor has to re-orient, and a meaningful share simply leave.

The homepage is doing a landing page's job

A homepage is built to serve every audience. A landing page exists to serve one intent. Sending paid traffic to the former is the single most common waste I see.

Forms asking for too much too early

Every extra field costs completions. Some of those fields exist because someone wanted them in 2021 and nobody has questioned them since.

Speed on the devices that matter

The page is fast on your laptop on office wifi. Your traffic is on mobile data, where a heavy hero image costs you visitors before anything renders.

What You Get

What is included

Fixed scope, tied to campaigns. This is not open-ended web design.

Built to match the campaign

One page per core intent, with headline, proof and offer matching the ad that brought the visitor there. Built and iterated by the same person running the campaigns.

Measurement and tracking setup

Before anything gets scaled, the data has to be right. GA4 and Google Tag Manager audited and rebuilt where needed, conversion actions deduplicated, Meta CAPI or server-side tagging where it applies, and offline conversion import so the platform optimises toward revenue instead of form fills.

Form and friction work

Field-by-field review of what you actually need before a first conversation, plus what happens after the submit, which is where a surprising amount of value leaks.

Testing with honest maths

Tests that run long enough to mean something. With most B2B traffic volumes, many A/B tests can never reach significance, and I will tell you when that is the case instead of reporting noise as a win.

Everything stays in your accounts

Your Google Ads account, your GA4, your tag manager, your landing pages. If we stop working together you keep all of it, history included. This should be the standard and often is not.

Scope is agreed up front: a set number of pages, a set number of revision rounds, a deadline. A new 5 to 8 page website is a separate fixed scope with a published price on landing pages and websites.

Pricing

The Challenge

  • Extreme keyword competition, with expensive clicks on the core terms
  • Dozens of local competitors bidding on the same terms
  • Seasonal demand swings affecting lead flow

The Strategy

  • Granular A/B testing of ad copy and landing pages
  • Negative keyword refinement to cut wasted spend
  • Audience targeting and full funnel restructuring

Google Ads and Performance Max in one of the most competitive local markets in the US, with expensive clicks, ZIP code choices and seasonal demand. The performance data is confidential by contract, so the case covers the work and the lessons, not the numbers. Read the case.

How It Works

How it runs

1

Diagnose

Where visitors drop, on which devices, from which campaigns. Data before opinions.

2

Build

Pages built around one intent each, matched to the ads pointing at them.

3

Instrument

Tracking that can actually tell whether the new version is better.

4

Iterate

Test what has enough traffic to be testable, and change the rest on judgement rather than pretending an underpowered test settled it.

What Is Different

How optimization works when it starts from the campaign side

  • Pages are changed to match what the ad promised and what the keyword asked for, which is where most paid landing pages lose.
  • Results are read on leads and sales, with call and form tracking in place before the first variant goes live.
  • Changes ship as small, measured iterations instead of a redesign that resets everything.
Who It Is For

Who this service fits

Advertisers sending paid traffic to pages that convert below what the campaign needs.

  • Companies that can ship page changes within days, not quarters.
  • Teams that want tests measured on leads and sales, not on clicks.

Not a fit: Sites without a way to edit pages, or without analytics to measure the change.

FAQ

Landing page questions

Do you build on our CMS or something separate?

Whatever gets pages live fastest without fighting your stack. Often that is your existing CMS, sometimes a dedicated landing page tool. It is a practical decision, not a religious one.

Can you do this without managing our ads?

Yes, but it works better together. The value comes from the person who sees the search terms also writing the headline, and that is lost when the two are split across vendors.

How many tests will we run?

Fewer than most vendors promise. Honest A/B testing needs traffic volume most B2B accounts do not have. Where volume is thin I make changes on evidence and judgement and say so plainly.

What if the page is fine and the traffic is the problem?

Then I tell you that. It happens, and it usually means the campaign is buying the wrong intent, which is a cheaper problem to fix.
