Even i get this question a lot of times. Once i just picked up the pen and did a little bit of research on the same. Steem Blockchain dApps are not found to be selling advertisements currently. There could be two prominent reasons
- They are getting Steem power delegations to generate enough income out of the curation rewards, which are probably bigger than the income generated by way of advertisements
- On order to advertise you need enough visitors coming over to your website and these dApps are probably in the phase where they need to be focussed on community building to a certain level, after reaching a benchmark number of users they can start accepting advertisements.
I analysed the alexa data of some of the most popular dApps and figured out that the rankings of these dApps are as follows
- Steemhunt ranks 130870 on 6.11.2018
- Musing ranks 448221 on 6.11.2018
- d.tube ranks 29533 on 6.11.2018
