Put your own spin on the romance formula.
In romance, there is a tried and true formula: girl meets boy, girl loses boy, girl gets the boy. To make your romance novels stand out, put your own spin or approach on the formula so your story feels fresh and engaging. You may have the girl meet a girl, or a boy meet a boy, which would fit into the queer romance genre. Or you may have the girl meet a boy in another universe or time period. Get creative and play around with the formula.
Have a strong setting.
The setting is a key element in a successful romance novel. The setting should be front and center throughout the story. It should dictate how the characters speak, how they interact, and how they interact, and how they see the world of the story
Create a central conflict.
Romance readers love a detailed, major conflict that drives the story forward. The conflict should be believable and prevent the main character and the love interest from being together. The conflict should also be clear and easy for the reader to follow.
Avoid cliches.
Romance writing is populated by many cliches, which are phrases that are so common they have lost meaning. If a phrase or line feels familiar to you, it's likely a cliche and to be avoided. Create unique descriptions instead that feel specific to your characters.
