The most common marketing mistake I see is not laziness. It is the opposite: authors pouring energy into a platform their readers were never on. “Be everywhere” is the advice, and it is a fast route to burning out while reaching almost no one who buys books.
The better question is not where should I post. It is where does my reader already spend time. Match those two and the same effort does far more work.
Do authors need to be on every platform?
No. You need to be on the one or two where your specific readers actually are, and to do those well. Spreading the same energy across five platforms usually means five thin presences and no traction anywhere. A single channel worked properly outperforms a scattered everywhere strategy almost every time.
Where are my readers, by genre?
It varies more than the “just do BookTok” advice admits. A few patterns that hold up:
- Romance and romantasy: TikTok is genuinely where much of this audience lives right now, alongside Instagram. This is the crowd BookTok was built on.
- Fantasy and litRPG: often Instagram and Facebook reader groups rather than TikTok. Dungeon Crawler Carl grew through exactly that, not through a viral BookTok moment.
- Thriller, mystery, and crime: these readers skew off Instagram. I know a thriller author with well over ten thousand reviews and only a couple of hundred Instagram followers, because his readers were never there. Newsletters, Amazon, and BookBub do the work for him.
- Literary, historical, and long-form: convert through direct sales, signings, bookshop presence, and word of mouth more than through online virality.
How do I find where my readers actually are?
Start from the books like yours that are selling, not from the platform you find easiest. Look at where comparable authors in your subgenre have real engagement, not just a presence. Ask your existing readers where they first heard about you. The answer is often not the platform you assumed, and it is almost never all of them.
What if I dislike the platform my readers use?
That is a real constraint, not a character flaw. If your readers are on TikTok and video drains you, you have two honest options: find a format on that platform you can sustain, or pick the next-best channel where those readers also gather and work it properly. A platform you quietly abandon helps no one. Fit matters as much as reach.
Frequently asked questions
Do I need to be on every social media platform to sell books?
No. One or two platforms where your actual readers gather, worked well, beat a thin presence spread across all of them. Being everywhere is how authors burn out while reaching few buyers.
Which platform is best for marketing romance books?
TikTok and Instagram reach a large share of the romance and romantasy audience right now. That genre is the core of what BookTok was built on, so it is usually worth prioritizing there.
Where do thriller and mystery readers find books?
Often not on Instagram. Thriller and crime audiences tend to convert through newsletters, Amazon, and BookBub more than through image-led social, so effort there usually returns more.
How do I figure out where my readers are?
Look at where comparable authors in your subgenre have real engagement, and ask your current readers how they found you. Start from your genre and reader, not from the platform you personally prefer.
