The amazon business website is almost the complete inverse of the consumer website. Everything from the photography, layout, and language to the content itself is completely different. It’s business centric, and is entirely focused on addressing the specific needs of a their business customers. It assumes that a business will need more information than a customer to make a purchase, and focuses on providing that -rather than catering to the more emotionally driven purchase of a typical consumer.
Still not convinced? To decide if your audience really can be marketed to in the same way, try asking the 6 basic journalistic questions (who, what, where, why, when, how) to both sets of your prospective customers. If the answers are the same, you might one of the very lucky few that can sell to both audiences without any change – I would be very surprised if this was the case though.
Even if you can use the same materials, and build out completely universal content. Consider carefully if you have the resources to chase both audiences. It’s much easier to focus your attention on one type of client – or perhaps one at a time, like amazon, consumers first then businesses(?)
