CoinURL have started 4 months ago as paid URL shortener like AdFly. During this time platform were almost completely redesigned, fixed many bugs, increased customer support quality. Now we offer for our users full suite of ad types and they can choose which best fit their needs. Recently we have started realizing full-featured contextual ads system the same way as Google AdWords/AdSense.
Interstitial ads – paid for each impressions, can be placed on the shortened links, as well as on the websites using overlay script (user visits a web page, get redirected to the ad page, then returned back to the source). This type of ads sometimes annoys users, but you get paid for each visitor regardless his interest in the visiting advertisers' websites. Waiting time before redirect, unlike AdFly and other competitors, is variable.
Banner ads – paid for clicks, similar to the Google AdSense. Non-intrusive, very high quality of the traffic for advertisers, safe. Available standard 12 text and image ad formats:
728x90
468x60
336x280
300x250
250x250
234x60
200x200
180x150
160x600
125x125
120x600
120x240
