Before you start making multiple random guides, put time into one you have already made. Go more in depth, explaining why you made things the way you made them, and insight into how you play the champion, allowing your readers to understand how the champion is meant to be played, why you play it that way, etc. jhoijhoi's guide on making guides is a great way to get started, its what helped me get my guide going, and have some success with it.
Hope this helps,
