If you need to create a perceptual map (or a positioning) map for more than 25 brands or products, then you will need to use the following Excel spreadsheet template. It is the same as the standard free template available for download on this site, but allows you to include up to 50 brands.
Because this Excel template is probably not for college students, there is a small fee of $4.99 for this expanded template.
Please note that the purchase is via PayPal and you will receive a link to download the spreadsheet immediately.
Tips for using the 50 brands perceptual map Excel template
As a suggestion, you should try to abbreviate the name of the firm or the brand as much as possible in order to ensure that your final perceptual map does not become too cluttered.
Depending upon your marketing goal, you may find that a multi-dimensional perceptual map (such as the correspondence analysis mapping function in SPSS) might be more suitable for you. This website has a free multi perceptual map template, which allows you to map up to 12 brands and 12 product attributes at the one time.
