You could be adding this note to tell us that there is an estate agents shop at this location, but...  there isn't. It's just a residential building: https://www.mapillary.com/app/?pKey=433707515232315&focus=photo&lat=51.57933158593602&lng=-0.14719257774652306&z=17

So I assume you're misunderstanding what these OpenStreetMap notes are for. It's not a way of letting you add a marker to advertise your website. You're welcome to add notes if you want to tell us something is missing or incorrect on the map.
