Why in steemit each article isn't paid?

I in steemit, am already a lot of time, and every day I try to publish a new post. But not so everything is simple how it seems from the first. I think an algorithm of social network is constructed so that who the first will manage to vote, that best. I so understand, the curator, doesn't even read full article, and votes seeing only the picture and heading. It is quite sad. Article can be useful.
For example we will sort my lessons of production of accessories from genuine leather.
1 lesson I have earned $24 https://steemit.com/art/@alex2016/how-to-make-a-women-bag-of-genuine-leather-step-by-step-tutorial-part-1-kak-sdelat-zhenskuyu-sumku-iz-naturalnoi-kozhi
When the 2nd lesson to me has allowed to earn $0.00 https://steemit.com/art/@alex2016/production-of-a-women-bag-from-genuine-leather-step-by-step-tutorial-part-2-izgotovlenie-zhenskoi-sumki-iz-naturalnoi-kozhi
3 lesson have brought me also $21. https://steemit.com/art/@alex2016/how-to-make-a-women-bag-of-genuine-leather-step-by-step-tutorial-part-3-kak-sdelat-zhenskuyu-sumku-iz-naturalnoi-kozhi
4 lesson have brought me money $0.01 https://steemit.com/art/@alex2016/how-to-make-a-women-bag-of-genuine-leather-step-by-step-tutorial-final-part-kak-sdelat-zhenskuyu-sumku-iz-naturalnoi-kozhi
I published these lessons practically in at one time.
Who to me after all objsnit the principle of network functioning of steemit. How to improve the earnings to more best results?

It takes time here on steemit, with your posts you could be getting more upvotes though out time. I googled "How to make a woman bag of genuine leather" I got your post in the first 3 responses.
Yes!
Each individual lesson was voted on by different people with different reputations. $45.01 for the series averages out to more than $10.00 per post. While this is not a large amount of money, it is an above average amount of money for posts to earn on Steemit.
Payouts for authors and curators are directly related to the price of Steem. The more Steem is worth, the more authors get paid. And the price of Steem is low right now.
Thanks !
