Advertising for Sri Lankan websites, built on the standards global buyers check.
addDuo connects local advertisers with Sri Lankan publishers. Advertisers launch self-serve campaigns from US$20. Publishers keep 70% of what advertisers pay, with every cent traceable in an append-only ledger.
How it works
One ad request, end to end, in well under 200 ms.
1. The tag asks for an ad
A 4 KB asynchronous script on the publisher's page requests an ad with the visitor's consent signals. The page never waits on it.
2. The auction picks a winner
Guaranteed deals first, then priority campaigns, then a unified auction between remnant campaigns and OpenRTB 2.6 bidders — all above the publisher's floor.
3. Only real views are paid
Bots and invalid traffic are filtered before billing. Viewability follows the MRC standard. Every charge and payout lands in the ledger.
