When you first sign up on entrecard.com to get web traffic, accept only ONE advertising offer the first day. You will only earn about 4 credits from them, something you can earn in less than a minute 1 minute of "Speed Dropping" on other peoples websites.
That advertisement will stay on your blog for one day. So when you go back to your EntreCard, cancel all of the pending adverts except the last one (most likely to be the highest paying). A maximum of about 7 advertisements can be pending for your advertisement spot at any given time, so you don't want people who want to pay 10, 20, or 60 credits unable to place a request because people who already sent requests in for 4 or 6 are taking up those spots, since after an advert request has been sent in, if the price goes up, their initial request only spends how much it was at the time they requested it. Unfortunately, it doesn't tell you how many credits each request was sent in for, but if you know how many credits your spot was worth when the request was placed, you can figure out how much they tried to advertise on your site for.
