Web data notes

Copenhagen hotel prices across 30 check-in dates

I built the tool used for this article and ran it myself on Apify. Every number below comes from the run IDs above.

What we measured

One run searched "hotels in Copenhagen" for 30 check-in dates in a row, 1 night, 2 adults, from the US in USD, 50 hotels per date (1,500 prices in all).

Findings

Run it yourself

Use days ahead instead of fixed dates so a scheduled run never asks for a past date.

{
  "queries": [
    "hotels in Copenhagen"
  ],
  "checkInFromDaysAhead": 20,
  "checkInToDaysAhead": 49,
  "currency": "USD",
  "country": "US"
}

The list Google returns can differ from what a browser shows. In my 8 October 2026 test, prices of the hotels returned matched a browser within 10% in 99% of cases.
