Content Warnings: Adult vs Sensitive Content
AuthorsAdult content and sensitive content aren’t the same thing. A book can be one, both, or neither — and conflating them causes problems for readers and retailers alike.
Two Different Questions
When thinking about content warnings, there are really two separate questions:
Is this book appropriate for minors? That’s the adult content question. It’s primarily about sexual content and explicit material that’s legally or socially restricted to adults. Retailers use this to filter search results, enforce age gates, and comply with regulations.
Might this content be distressing to some readers? That’s the sensitive content question. It’s about material that could be triggering or upsetting regardless of the reader’s age — depictions of suicide, eating disorders, abuse, animal death. A reader who’s lost a pet might want to know before starting a book where the dog dies. A survivor of assault might want to avoid graphic depictions of violence.
These questions have different purposes, different audiences, and different answers.
Adult Content
Adult content flags exist primarily for gatekeeping. They tell retailers “this book should not be shown to or sold to minors” and they tell parents “this is not appropriate for your child.”
The threshold is usually sexually explicit material. Violence, strong language, and drug use might contribute, but sexual content is the primary driver. A graphic thriller with extreme violence is often categorised differently from a romance with explicit sex scenes, even though both might be “adult” in the colloquial sense.
When you mark a book as containing adult content, retailers may:
- Exclude it from general search results
- Require age verification
- Restrict advertising options
- Apply different content policies
This isn’t censorship — it’s categorisation. The book is still available; it’s just filtered appropriately.
Where Adult Content Flags Go
Most retail platforms have an adult content field in their upload process:
- Amazon KDP has a simple yes/no “Adult Content” checkbox
- Apple Books has content ratings and descriptors
- Kobo Writing Life has an adult content flag that affects catalogue placement
- Draft2Digital and similar distributors pass the flag through to retailers
The flag is usually binary — adult or not — without much nuance. When you upload directly to retailers, you’ll set this in their dashboard. When you use a distributor or metadata feed, it’s included in the file.
Sensitive Content
Sensitive content warnings serve a completely different purpose. They’re not about restricting access — they’re about informed choice.
A book about recovering from an eating disorder might be appropriate for teenagers and valuable for adults, but someone currently struggling with disordered eating might want to know what they’re getting into. A mystery novel might be perfectly mainstream, but if it includes a detailed suicide scene, readers who’ve lost someone to suicide might appreciate a heads-up.
Common sensitive content warnings include:
- Suicide or suicidal ideation
- Self-harm
- Eating disorders
- Sexual assault or abuse
- Severe bullying
- Graphic violence
- Animal harm or death
These aren’t age restrictions. A book with sensitive content warnings might be entirely appropriate for a 15-year-old — but that 15-year-old (or their parent, or any reader) deserves to make an informed decision.
Where Sensitive Content Warnings Go
Here’s where practice diverges from theory. Most retail platforms don’t have dedicated fields for sensitive content warnings. The industry metadata standards support them, but retailer systems often don’t.
In practice, authors communicate sensitive content warnings through:
- Front matter — A “Content Note” or “Content Warnings” page before chapter one has become common in romance, YA, and literary fiction
- Book descriptions — Either at the end of the blurb or as a separate paragraph
- Author websites — A dedicated page listing content guidance for each book
- Back matter — Some authors put warnings at the end to avoid spoilers, with a note in the front pointing readers there
Reader communities have filled the gap too. StoryGraph has user-contributed content warnings. Goodreads users tag and discuss content. Book bloggers often include warnings in reviews.
This isn’t ideal — authors shouldn’t have to manually add the same information in multiple places — but it’s the current reality.
Why Both Matter
Consider a dark romance novel with explicit sex scenes and a subplot involving an abusive relationship. It needs both:
- Adult content flag — because of the explicit sexual content
- Sensitive content warning — because of the abuse depiction
Now consider a young adult novel dealing with a protagonist’s eating disorder recovery. It might have:
- No adult content flag — it’s appropriate for teens
- Sensitive content warning — because eating disorder content can be triggering
And a cosy mystery with mild romance and no violence? Probably neither.
The two systems are independent because they answer different questions for different purposes.
The Reader Perspective
Readers increasingly expect content warnings, particularly for sensitive material. This isn’t about being oversensitive — it’s about respect for readers’ autonomy and experiences.
Someone dealing with grief shouldn’t have to stumble unprepared into a detailed death scene. Someone in recovery shouldn’t be blindsided by content that might set them back. Providing this information costs the author nothing and gives readers the information they need to engage with books on their own terms.
What This Means in Practice
When preparing your book’s metadata, think about both dimensions separately:
For adult content: Is there sexually explicit material that would make this inappropriate for minors? If yes, you’ll flag it when uploading to retailers.
For sensitive content: Is there material that might be distressing regardless of age? If yes, you’ll need to communicate it through your description, front matter, or website — at least until more retailers support structured warnings.
Many books will have neither flag. Some will have one or the other. A few will have both. All of these are fine — the point is accurate information for readers, not avoiding flags.
How Pubblish Handles This
Pubblish treats these as two separate systems. You can mark a title as containing adult content, containing sensitive content, both, or neither. Each has its own set of specific warnings you can select, plus space for anything not covered by the standard list.
This information is stored properly in your metadata, ready for retailers that support it. For retailers that don’t, you’ll still have a clear record of what warnings apply — useful when writing descriptions or creating front matter.
