Depends this is rather vague question in many aspects. For example I can put up a image website and get 5000 uniques but guess what you wont even make $5 with that number of uniques. On other hand say you have a website about cellphones and other stuff then that 1000 uniques could make you good cash. Basically 1000 uniques mean nothing its all about good niche that pays good cash. On Average 1000 uniques is nothing if we look at different low niches.
