The
advertisement systems on EntropiaLife are actually very affordable and easy to manage. The maximum price for a banner that will be seen by all 20,000 users on EntropiaLife.com is 50 peds per week (nearing 3,000 unique viewers per day internally, meaning they have an account).
Advertisements within EL are significantly less expensive than typical web ads, and are targeted specifically at only people within EU. You can adjust the target audience of your ads as well, by selecting mobs from the menu, this will only target people that global on those mobs, so you're able to pay less if you just want to advertise to beginners (select argonaut, daikiba etc.) or just to high level players (eomon, malcruenter etc.) You can even track how many views on your advertisement as well as click throughs, which is then broken down to show you.
If you put 100 ads in the system, sure your ad will show more often, the same way it does through the in game banners, however with the traffic on Entropia Life, we think the value you get for your advertisements is extremely reasonable to the user.
