Custom Ink ran a lift test with Social Fulcrum to determine the real impact and incremental return on ad spend (ROAS) from its Facebook advertising campaigns. The test showed that Custom Ink's real ads generated $620K in incremental revenue over the control ads, resulting in a 15x incremental ROAS. This data provided Custom Ink the confidence to ask its board for funding to expand its Facebook advertising, which led to an 850% growth in Facebook revenue over the next two years.
