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. Searchable text sellers put in their listings must be directly related to the item being sold.
Tony wants to sell a backpack on eBay. It's not a brand-name backpack, so he's concerned that if he just lists it as a "backpack", no one will find his listing. He often carries his Apple iPod with Sony headphones in his backpack, so he decides to list his generic backpack as "Black backpack fits iPod w/Sony headphones". Is it OK for Tony to list his backpack this way?
