I recently made a website with some friends and wanted to make some money with it. So we decided to do an application with adsense. A few days later we got the message that our website had insufficient content. So we added some articles to our site with some text, and tried again. But again we got a mail "insufficient content". Now we tried it again and we got the same mail.
So, we clearly have insufficient text-content on our site, but when do we have enough? Like do you need to have hundreds of pages full of text, or are some short texts already enough?
