80% of leaflets response is about dropping through the letterbox as they need a carpet cleaner, but this does not explain the jobs i do where they show me a leaflet thats years old...... were they have stuck it in the draw and forgot about it.
some people do plan ahead, they might be decorating next month or having a wedding or family visiting in the summer holidays or moving out of a rental property and have to have the carpets cleaner..... so they will keep the leaflet, if it looks professional as they may receive 3 or 4 leaflet between keeping your leaflet and actually being ready to call you. if your leaflet is crap they will keep the next leaflet.
