Keyword spamming happens when members put brand names or other inappropriate keywords in a title or description for the purpose of gaining attention or driving members to a listing. Words that sellers put in their listings must be directly related to the item being sold.
A seller wants to list a rucksack on eBay, but it has no distinct brand. Concerned that no-one will find it, the seller decides to list the rucksack as "Black rucksack fits iPod w/Sony headphones". Is this permitted on eBay?
