In German, 'der Counter' refers to a service counter (e.g. at the airport) or a counter/counting device (e.g. on a website). It does not mean the work surface in a kitchen; the English word 'kitchen counter' would be 'die Arbeitsplatte' (countertop/worktop) or 'die Küchentheke' (kitchen counter) in German.
Die Tickets erhalten Sie direkt am Counter der Fluggesellschaft.
You can get the tickets directly at the airline's counter.
The meaning becomes clear from the context. In airports, hotels, or shops, it means the service counter. In connection with websites, technology, or games, it means the counting device.
Am Service-Counter konnte man mir sofort helfen.
They were able to help me right away at the service counter.
As a service counter, 'Counter' is often used in compound words. Typical examples are 'Check-in-Counter' (check-in counter), 'Service-Counter' (service counter), or 'Info-Counter' (information counter).
Wir müssen unser Gepäck am Check-in-Counter aufgeben.
We have to check in our luggage at the check-in counter.
As a counting device, 'Counter' is often found in combinations like 'Besucher-Counter' (visitor counter, for a website) or 'Punkte-Counter' (points counter, in a game).
Laut dem Besucher-Counter waren heute schon 500 Leute auf meiner Homepage.

advertisement / report / display
'die Anzeige' and 'der Counter' can both have to do with numbers or information on a device. An 'Anzeige' is what you see: for example, a number, a symbol, or a message on a display. A 'Counter', on the other hand, is a counter that counts events or things. Learners may confuse the words because a counter often shows a number on a display. In practical terms: the Counter counts; the Anzeige shows the result.

Der Counter auf der Webseite zählt jeden neuen Besucher.
The counter on the website counts every new visitor.
Auf der Anzeige steht, dass der Akku fast leer ist.
The display says that the battery is almost empty.
