Most roadmap imagery is available from zoom levels 0 to 18, for example. With zoom level 0 the whole world can be visible. As we all know, the more we zoom in on Google Maps, the more spots (e.g. name of restaurants, hotels etc.) are visible. Some spots are visible "sooner" - with a lower zoom level, which is of course better for the company. Some companies are only visible with a very high zoom level. If I have a highly branded company is the zoom level lower? Is this the answer for the different display?

Don't take that question too serious but all answers are welcome 😉 Answer to all:
