1. Present simple tense: Used throughout the answer (e.g., "Offline advertising still has its strengths," "billboards and posters are hard to ignore") to state general truths and opinions, which is appropriate for IELTS Part 3.
2. Relative clauses: "who aren't online much" and "like those on buses or unique flyers" are used to add detail and clarify meaning, showing good command of complex sentences.
3. Modal verbs: "can leave a lasting impression," "can be really memorable," and "can even start conversations" use the modal verb "can" to express possibility and ability, which adds nuance.
4. Comparative structure: The answer compares online and offline advertising by highlighting the unique benefits of offline methods, though it could be improved by directly contrasting both sides.
