Let be one thing clear. Good content here is different from good content elsewhere.
Here some curators decide what good content is. A post <20 Steem is good content and those 20 Steem are not necessary given by the "crowd" here.
If you like it or not: a photo, a meme, an @actifit post, a drawing, etc only are not seen as good content.
You have to write text to it. Some say 44 words I say write more try the 50 or better 200.
What you write about is not important as long as you use your own words. This is meant by original. You need to write it, not copy-paste someone else's work.
Citing a text from the bible, some scientist, writing down an idiom is also not original work.
Most curators (those who upvote you) will not read what you wrote. That explains why you have 20 votes right after you posted and not one single comment.
Those votes are done automatically. You can use steemvoter to vote on posts of certain Steemians you like or think they write good content (see the tips underneath).
It is not appreciated to selfvote so my advise is not to do it or make a habit out of it.
To keep it simple @upvotebank uses the votes you do not use to upvote a post from you. Your vote is not wasted and you have an extra upvote.
I tried it with this account and I did not receive a link (I did with my other account). The reason? Acvording to their rules they should so the only reasons I can think of are: I write bad content, I do not post frequently enough, my votes are useless, I had a downvote or I used all my votes (I am using steemvoter with this acvount).
