How do ad extensions influence Ad Rank?

• A. They have no effect on rank
• B. Using a variety of ad extensions can help improve your rank
• C. They reduce click-through rate
• D. They only increase cost

Answer: (B)

Ad extensions boost Ad Rank by improving the ad’s perceived quality and click-through potential. Ad Rank is calculated from bid and Quality Score, and Quality Score reflects expected CTR, ad relevance, and landing page experience. Extensions add more relevant information and options for users (like extra links, phone numbers, or prices), which generally makes the ad more useful and increases the chance someone will click. That higher expected CTR feeds into Quality Score, helping the ad rank higher without changing the bid. So using a variety of extensions properly can lift your rank. They don’t have no effect, they don’t inherently reduce CTR, and they don’t merely increase cost.
