I have a few pages. One just hit 15k today. It is growing at 150 fans per day. I wanted to post articles. But I was wondering how much adsense pays per 1000 visitors? And also how many ads can I have on the article page with the images? I've seen some with 2, and up to 25 ads from google adsense on it. Is there a limit of how many ads from google can be placed on it? And a price area? All my fans are from the USA and some from Canada. Thank you in advance.
