Generating $120 for every $1 of Ad Spend (ROAS) for IFA

case study

Case summary: $120 for every $1 of ad spend for the IFA Congress

After two years of virtual meetings, the International Fiscal Association (IFA) needed to re-engage its global network of tax and fiscal law professionals and attract new leads for its in-person congress in Berlin.

What we did

Kabloom designed and built the website and ran digital advertising, email marketing, and social media advertising, boosting, content and live management. We profiled personas, chose channels by industry, company and audience behavior, and integrated a 360-degree conversion funnel so every persona was reached at the key milestones.

The results

The campaign delivered 20% of total registrations and $120 in return for every $1 of ad spend, and the congress beat its target by 8%.

Why it worked

An e-commerce-ready website and a funnel built around personas meant ad spend turned directly into registrations.
