Case Study: TaxSlayer Pro achieves 240% more net conversions and 14% lower CPA with Trustpilot

How TaxSlayer Pro upgraded their B2B ad campaigns with customer reviews

TaxSlayer Pro, a tax‑preparation software built by tax professionals for tax professionals and used to file millions of returns each year, faced the challenge of convincing busy tax preparers to switch tools in a risk‑averse market. Prospective customers were hearing only TaxSlayer Pro’s messaging, so the company needed credible third‑party validation to cut through the noise and build trust.

TaxSlayer Pro partnered with Trustpilot to collect and showcase customer reviews across Facebook ads, their website redesign, and email campaigns. Ads featuring Trustpilot testimonials delivered 240% more net conversions and a 14% lower CPA, while the company now boasts a 4.7‑star rating and a 92% retention rate—creating a feedback loop of satisfied customers turned brand advocates that boosts acquisition and product improvement.
