WeChat unveils today a new self-serve advertising system for public accounts to monetize the traffic of their accounts or buy display ad placements in WeChat pages of other public accounts. There are two categories of public accounts on WeChat platform, service account and subscription account. So far most subscription accounts are operated by content providers such as media, and businesses who’d leverage WeChat to do business would register service accounts. The new ad system, like many others, has a dashboard for advertisers to monitor ad performance: impressions, click-throughs, new followers of advertisers’ accounts, etc. Currently only public accounts with more than 100,000 subscribers are allowed to join the program.
