- Who is the Incrementality poster for?
- Incrementality belongs to the Marketing section rather than to a school year, because business is not something one grade owns. Anyone learning digital can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Incrementality poster?
- Attributed conversions are not caused conversions. Only a holdout test separates them. A wall chart earns its place by being glanceable from where the work is happening, so Incrementality belongs on the wall where that business work actually happens, within glancing distance, rather than filed away.
- What other posters go with Incrementality?
- Attribution, Content Marketing and Conversion Optimisation sit alongside Incrementality in the Marketing section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AttributionContent MarketingConversion Optimisation
- Is the Incrementality poster free to download and print?
- Yes. Incrementality downloads as a free PDF with no account, no email and no watermark, like everything else in the Marketing section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Incrementality poster print at?
- Incrementality is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Incrementality loses nothing.Printing guide
