Hi Steemian, hope you are well.
It is hard to increase reputation in steemit or Dtube now a days. But there is always a option to do it.
If anyone do hard work then they can increase reputation quiet well.
The following are the few steps I have given:
- Quality of the content is most important thing.
- Make a topic which suit you & you have a good knowledge on it.
- Use some easy understandable word so that everyone can easily understand.
- Always add video or image in the post to give a good attractive look.
- Don't do copy, paste. It is strictly prohibited.
- Promote your post using social media platforms.
Comment your suggestion.
