The title says it all. What percentage of sites get over 1,000 uniques daily that is real targeted traffic and is not useless robot stuff. How many do you think it is or do you actually know. I think around 10 - 25% of sites would get on average over 1,000 uniques a day and the rest totally either don't know how to advertise their sites, don't have the time, or just find it to hard to find the traffic. I've just thrown this out of the box really and have not got any evidence of whether I am right or not. But with knowing that you can get an Alexa ranking of under 500,000 with less than 1,000 unqiues a day, then that tells you something even though it's not 100% accurate. Another thing is the amount of sites that purchase their domain one year and then never renew their domain once it's about to run out. It seems that more sites fail than succeed when it comes to getting traffic. What do you think?
It's hard to answer your question. it's all depend on many factors such as niche, promotion, marketing, content, target market and etc. maybe if you want to do a research you need to narrow the topic down a bit.
I think it's probably a very small proportion. You have to factor in all the sites who never intend to get that much traffic. Blogs that are just personal journals intended to be share amongst friends and family, for example, or businesses that just have a one page site attached to their bricks'n'mortar store, just to provide a map and a phone number.
