how many pageviews per day to sell ad spots
 

Is 250k per day enough?

Wouldnt uniques be a better measurement?

not really. uniques doesn't take multiple page views into account, which translates into more ad views per unique. ie, one visitor might see 10 different ads.

On one site, I get about 17 page views per visitor. One another, it's only about 3.

Uniques would be a lot better to know how many people view the stie and not how many times viewed

Yeah man I can make a site with 250k pageviews easily, 250k uniques now thats quite a different beast.

250K page views and 100-150K uniques sounds about right

10 pageviews per person for a total of 250k pageviews is 25k unique lol

lol. I didn't say how many page views per person.....
