Start with a local question. Keep the network, language, and delivery settings separate so the result tells you something useful.
Keep Greek script and transliteration separate
For Greece search QA, save a Greek-script query and test a Latin transliteration as a second case if relevant. Compare result matching and text encoding with the country route unchanged. This reveals search-language behavior without attributing every difference to the proxy exit.
Split mainland and island delivery tests
Compare an Athens delivery example with an island destination your Greece service supports. Record available methods and quoted dates after address entry. A country-level network sample cannot establish which island a customer lives on or whether a merchant ships there.
Hold travel dates and occupancy constant
When inspecting a Greece travel page, fix destination, dates, occupancy, room type, and cancellation conditions before comparing routes. Keep the first quoted currency and final checkout amount. A lower headline price may belong to a different product rather than a geographic price difference.
