Other than Google Adsence, I think Ads can be put at specific place and needs according to @aggroed's post https://www.steemleo.com/nitrous/@aggroed/nitrous-update-ads

There's no setup cost or anything like that for advertisers. We'll need files to upload to the adserver and you'll have to let us know how many impressions you want. Impressions are currently priced at $1 per 1000 impressions ($1 CPM).

Intelligent Ad positions (which should be much more aesthetic) can be sold to advertisers directly for CPM. For example, a banner at the top, sides or middle will not bother most users. More specifically ads will be more appropriate since Advertiser are aware of audience while Google Ads are driven by (dumb) AI that can bother people.

Ads should be aggressively sought out for now, since most users are still using Chrome or other browsers, it will take long time to switch to brave.
