Which of the following queries demonstrates a transactional intent?

Transactional intent refers to the user's intention to complete a transaction, such as making a purchase or booking a service. In the context of the provided choices, the option "buy shoes online" clearly indicates a desire to engage in a commercial transaction. The user is looking to obtain a product—shoes—through an online purchase, which directly aligns with this intent.

The other options focus more on informational or navigational queries rather than transactional ones. For instance, searching for how to improve a resume reveals an interest in gathering information or learning, rather than completing a purchase. Similarly, finding the best coffee nearby may imply a desire to go to a location, but it does not necessarily indicate an intention to buy coffee at that moment. Lastly, asking about the weather is purely informational, as it seeks to acquire knowledge rather than initiate a commercial exchange. Thus, "buy shoes online" is the only option that encapsulates transactional intent effectively.
