An advertiser who sells coffee beans adds the keyword “Java” to an ad group. After two weeks, she runs a placement performance report and notices that the ad is showing up on websites about JavaScript programming. What should she do to avoid appearing on these irrelevant sites?

• Exclude “Programming” as a topic
• Add “Coffee beans” as a topic
• Make it obvious in the ad copy that “Java” refers to coffee, not JavaScript
• Add “Java beans” as a negative keyword
