1. Present simple tense: Used throughout the answer (e.g., "play a big role," "encourages others to visit") to state general truths and habits, which is appropriate for this type of question.
2. Conditional clause: "If friends or family rave about a city, it often encourages others to visit" uses a first conditional structure to show cause and effect, which adds complexity and clarity.
3. Present participle phrase: "sharing their experiences online" is a present participle phrase that adds detail and shows an ongoing action related to influencers and bloggers.
4. Infinitive of purpose: "to travel to," "to visit," and "to get a real sense" are all examples of using the infinitive form to express purpose, which is natural and fluent in spoken English.
