Landing page split tests for a mold inspector: +87% conversion rate
Test run byKlientBoostCRO agency
Commentary byLiftArchiveOur analysis, not theirsMold Inspection Sciences saw its conversion rate rise 87% and cost per lead fall 47% over about a year of landing page split tests and paid search changes by KlientBoost.
KlientBoost ran the work and published it as a PDF case study.
The page tests ran alongside new single keyword ad groups, call-only CTAs, in-market audiences and broad match targeting, so no single page change is credited.
- Conversion rate: up 87% across the engagement.
- Conversion volume: up 274%, a far bigger lead count.
- Cost per lead: down 47%, close to half the earlier cost.
- The figures cover about a year. Individual page test results, sample sizes and significance were not shared.
The change
Split-tested page versions with a clearer booking path and call option.

Control
Before the engagement the company ran its own Google Ads, with mixed results, sending paid clicks to its existing pages.
Variant
KlientBoost ran a series of landing page split tests while also restructuring the account. The details of each page test were not shared.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Running many page tests over a year lets small wins add up, which a single redesign rarely matches.
- Mold problems feel urgent and worrying, so pages that reassure and offer a clear next step are likely to convert better.
- In-market audiences and broad match brought in more searchers, which drove much of the volume growth.
- Call-only CTAs on some ads let anxious homeowners phone right away instead of filling in a form.
Caveats: This is an agency-reported before-and-after result from a full paid-search engagement, not a split test. Ads, keywords, targeting and landing pages all changed together, no sample size or significance was shared, and the date is not stated. The changes ran over about a year, and the individual page tests were not reported.

How to run this test on your site
- Hypothesis
- If we run a steady series of split tests on our paid landing page, starting with the headline and form, then more homeowners will book an inspection because each round removes a source of doubt.
- Primary metric
- Inspection bookings and calls per paid visitor
- Guardrails
- Cost per lead
- Booked inspections per lead
- Call answer rate
- Who should test it
- Home inspection and remediation services with enough paid traffic to finish a test every few weeks. If you get only a handful of leads a week, focus on bigger changes rather than many small tests.
Questions
How many landing page tests should a service business run?
Run one test at a time on your main paid page, then move on once it reaches a clear result.
Over months, a steady stream of tests tends to beat one big redesign.
What should I test first on a home service landing page?
Start with the headline and the main call to action, since most visitors see them first. Then try trust signals and form length.
Why did conversion volume grow more than conversion rate?
The account also reached more searchers through broader targeting.
More traffic at a better rate multiplies into many more leads.
