Sample sentence
According to a Chateaupedia study of Google searches, the most searched-for castle in Rhein-Sieg-Kreis in 2026 is Schloss Drachenburg, with 60,500 searches a month.
Method
The volume used is Google Ads data, read from DataForSEO: the average monthly searches for the castle’s name over twelve months, from Germany and in German (“Schloss Neuschwanstein”, “Burg Eltz”). Each name is re-read every ninety days.
The filters are those of the French study. With no Google reviews and three Wikipedia languages or fewer, a volume of 5,000 searches or more almost always measures something else (a town, a holiday park), and the name is set aside. When Google knows the place, the volume is capped at twenty times its reviews. Names made only of generic words (“Altes Schloss”, “Burgruine”) are set aside, and namesakes count once.
The area is that of the castle’s address: its state, its district or its district-free city. An area has its page from three searched-for castles. Media may reuse these figures by crediting Chateaupedia with a link to the page.
