For a travel agency, I'd build SEO pages that answer the three biggest questions people have before booking: "Where should I go?", "What should I do there?", and "Is it worth it?"
First up - destination hubs. A single page per country or city that bundles all your relevant blog posts, videos, and guides into one pillar. Internal link to that hub from every piece of micro-content you create.
Next, itinerary templates. "7 Days in [Place]" or "Budget vs Luxury [Place]" - these rank well because they target specific search intent (planning mode). Bonus if you include a downloadable PDF version (great for lead gen).
Then packing lists and seasonal guides. Low competition, high conversion. Someone searching "what to pack for Iceland in winter" is already close to booking.
Last, comparison pages. "Tokyo vs Seoul for first-time solo travellers" or "All-inclusive vs self-guided in Greece". These capture people in the final decision stage and let you repurpose one piece of research into multiple formats (infographic, carousel, short video).
Structure each page with a clear content cluster approach - one pillar, five supporting posts, all interlinked. That's how you turn a single destination feature into weeks of SEO momentum.
