Alamy Keywords and keywording

Anyone who thinks they can just add and then forget about their keywords with stock is fooling themselves. Every time I check 'Your Images' on Alamy I always end up discovering words or phrases that were initially left out. And you know what one of the biggest mistakes is ? Yep, it's plurals. Even if the image doesn't have more than one of whatever, the plural version might just be a commonly accepted description or phrase used for that subject. And don't forget those American spelling variations either. Or even commonly accepted wrong spellings for certain words.
