Things like a good product description, in-store display or a deliberate ‘call to action’ among others which makes a customer purchase a product/service is a purchase trigger. E.g. Wal-Mart’s tagline – ‘Everyday low prices’ could be a purchase trigger for consumers to come to the store and make a purchase. H&M’s low-cost high-fashion strategy can also be a purchase trigger.
A company’s website is useful for understanding purchase triggers. Conversion patterns, visitor click-streams or website traffic can be analyzed in detail to understand the customer’s actions – whether he/she makes a purchase or exits from a website.
