This depends on where your actual customers are searching from. Here’s a quick way to check, rather than guessing.
1. Check Where Your Current Bookings Come From
In Google Analytics, go to Reports > User attributes > Geographic details. Compare visitors searching from within your country/region against international visitors.
2. Check How Close to Booking Your Traffic Is
Cross-reference with the report from How to Read the Reports That Actually Matter in Google Analytics: are location-specific visitors reaching your booking page more often than general/international ones?
3. Decide Your Primary Focus
If most of your enquiries already come from local or destination-specific searches, prioritise local SEO first (Google Business Profile, local content, reviews). Treat international content as a longer-term addition once local fundamentals are solid, not a parallel first priority.
