but like i said in a previous post or comment to my post:
It's very clever from EntreCard to hide the sponsored ads in the menu of the Dashboard and not like in the past show them publicly beside the regular EntreCard ads.
UPDATE (ONE DAY AFTER THE LAUNCH OF THIS AD and three more joined):
EntreCard promotes now additional in the blog sponsored ads as there are now a few advertisers who try this service. As of now i saw that this ad is an EntreCard-Blog in the category "Graphic Design". The ad price is now 128 EC (don't know the price from yesterday but i guess it was significantly lower). Seems like EntreCard uses this ad price as example for their prediction that your ad price could jump up to 2.000%.
I'm not sure if it would be worth for you to pay 128 EC when you got in the last five days just 142 visitors (less than 30 per day).
On my blog there would be around 10 - 15 ad views for this paid ad and another 10 - 15 ad views for the other 2 or 3 ads.
This means for the TOP 30 popular blogs, there might by up to 450 ad views/daily. Looking at the TOP 300 blogs with 120 - 450 visitors daily we would get around 2.000 ad views/daily for this sponsored ad.
At the moment i guess it's around 75 - 100 visitors that you can get per day as i looked just now after i discovered the ad one day ago. Will look tomorrow again, where the popularity is now and see if it raises now faster above the 200 mark.
There are now EIGHT SPONSORED ADS IN THE SYSTEM, you might have a look and judge yourself who can be disabled :)
How many EntreCard members look daily in the sponsored ads if there are new ads to uncheck?
