BUSINESS OBJECTIVE
Conversion Rate Optimization
The challenge: Before working with ConversionLab, Campaign Monitor didn't have a process or resources for dedicated conversion rate optimization. Through their PPC agency they had seen amazing numbers in traffic, but had yet not tapped the full potential on converting visitors to signups for trial accounts. Nobody was systematically asking: what happens after the click?
CASE STUDY
With A/B testing we have continued to tweak conversion rates with a total of 1187% across 33 tests on several landing pages. The average lift in conversion per test is at a stunning 36%. Below you can see one of these tests.
Campaign Monitor converted 271 abandoning visitors into leads in just one month by offering their email marketing guide to users just as they are about to leave the page.
โWe havenโt had to create any new content or pages,โ says Shamita Jayakumar, Senior Marketing Manager at Campaign Monitor. โInstead, weโre leveraging the content we already have and getting it in front of marketers who can use it. It really has been a case of creating something from nothing.โ
ConversionLab played a key role in accelerating Campaign Monitor's growth by optimizing our landing pages for maximum performance. We increased conversion rates by 260% in the first 6 months and 1187% cumulatively across the full engagement, and saw a 64% reduction in customer acquisition cost. We are very happy with the results!

By using dynamic text replacement, we can tailor the content to match each and every ad on Google Ads without having to create multiple pages. The tight message match ensures higher relevancy for the user, and Google rewards you with a higher quality score as they too will see the message match. The below example gave a 58% uplift in conversion rates using dynamic content.

Over the course of the engagement we ran 33 A/B tests across 10 landing pages. Not every test won โ and that rigour, being willing to kill a losing test and move on, is what made the cumulative result possible. Here are the five tests that defined the engagement:
In the first 6 months, cumulative CVR improvement reached 260%. By the end of the full engagement โ 33 tests across 10 pages โ the cumulative total reached 1187%.
Each winning test raised the baseline for the next. A 36% uplift applied to a page already performing 260% better than baseline produces a much larger absolute improvement than the same 36% applied to the original.
This is why sustained retainer-based CRO consistently outperforms one-off optimisation projects.
Analyse landing page performance and visitor behaviour to identify what's preventing conversions. Not guesswork โ data-led hypotheses based on what the numbers actually show.
Every change starts with a specific, directional hypothesis. We define what we expect to improve, by how much, and why. No test runs without a reason.
We isolate a single variable and run the test until reaching 95% statistical significance. We never stop early because results look promising โ and we're willing to kill a losing test and move on.
Every winning test raises the baseline for the next. The longer the engagement runs, the faster the results accumulate. This is why a sustained retainer consistently outperforms a one-off sprint.
