A user searches for a disposable straw, and the ad shows stainless steel straws. Which category is this?

• A. Radically Different Alternative
• B. Substitutability
• C. Nearby Intent
• D. Only Topical Connection

Answer: (A)

When evaluating user intent, the key idea is whether the ad offers a solution that matches the exact product the user is seeking or a fundamentally different approach. The user is looking for a disposable straw, which implies a one-time-use, typically plastic or paper option. An ad for stainless steel straws presents a reusable alternative, which changes the product category entirely. This is a radically different option because it aims to solve the same drinking-straw need but with a long-lasting, reusable instrument instead of a single-use item. It isn’t a direct substitute within the same category (disposable straws), and it isn’t just tangentially related to the topic. So the best fit is radically different alternative.
