Post visibility on steemit is purely a function of the value of upvotes you've gotten. Once a post reaches a certain amount of upvotes it will appear on the hot or trending page. Depending on what tags you used, your post could appear on multiple hot pages. For example if you made a post using the tag 'poetry' that's received 20 dollars worth of upvotes, it will most probably appear on the hot page for posts using the tag poetry.

As long as the value of the upvotes you've received are high then your post will be on the hot page, and by extension will increase its visibility. Work hard and create quality posts and most definitely you will get the upvotes you deserve. If you really want your posts to be visible, then you could simply pay for a large upvote and get your post on the hot page that way.
