It’s difficult to split test carpet cleaning leaflets as it takes a large number to get usable data. You need to put out 2000-3000 of each so would need to print 2 different leaflet.
Best to learn from other people experience and copy their leaflet😎😎
The best leaflet is the leaflet that is constantly reordered and delivered. the person who knows this is the printer, ask him which carpet cleaning leaflet keeps getting printed because if it’s getting reordered then it must have worked the first time
