- Outcome: Won
- Page type: Landing page (Lead-gen)

Mold 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.

## Result

**+87% conversion rate**

- 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.

## 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)

- 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

- 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
- Guardrail: Cost per lead
- Guardrail: Booked inspections per lead
- Guardrail: 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.
