With almost half my sales from keyword searches, it reinforces the need to effectively keyword to make sales.
Many of the searches resulting in a sale are words describing the photo in a very direct fashion however, 5 of the 45 (11%) are of a concept represented in the image. That said most of my photos are very topical so I guess not surprising however, at the same time it focuses my efforts into how I will keyword. I think the main thing is to ensure the images are discoverable by keyword searches of what the photo is primarily of - stacks of keywords surely results in a poorer location in a search through a dilution bias applied by the indexing. Surely buyers are rarely tempted by a loosely related image to a keyword.
Just some thoughts - I'd be interested to know others break downs and statistics of their sales from keyword identified sales.
