> Essentially it's a way to pay for ad space in communities or websites by turning the ad into a post, so it's a payment to promote the post.
Yes, communities, websites, games (e.g. @splinterlands) can create "ad_spaces" and accept payment for them
> Monetizers can accept any hive-engine token and can decide whether they want to burn the token or keep it to themselves.
Currently, HIVE is the only supported token, more tokens are planned for integration (SMTs or Hive-Engine)
> Can monetizers burn 50% of the payment and earn the other half? (or any other percentage)
That sounds like a good idea. It is possible to implement that in an update. I'd have to design that feature.
> Can monetizers sell ad space which is not a hive post, for example a banner ad similar to the old Steemit, Inc ads, while using native ads?
Great question! Yes they can. More ad types are planned in the next update. Essentially, all ads will be posts containing Native Ads metadata, but the difference will be that post_global posts will be treated as normal posts and other types e.g. banner image or slideshow will be parsed differently so they won't show up as posts. I'll probably include the hidden flag in the requirements so that front-ends can hide the other types of posts from people's feeds.
> Is it possible for me to create a frontend for advertisers ...
Yes! Please do. This is needed. So my vision is that a front-end can either have customized interfaces for advertizers, if they want to have that. But there should also be a dedicated front-end that exposes all Monetizer accounts on Hive. Similar to the Google Ads Dashboard.
That will create a big, dynamic market, where other stats can be incorporated to give detailed info about each Monetizer's offering. Then maybe 3rd party marketers can leverage it like they do Google Ads.
Thanks for your feedback. Much appreciated!
