The 14 platforms, explained — and which ones an author actually needs

Author Automations Social supports fourteen platforms. I'm going to give you the honest map of all of them, and then I'm going to tell you which three or four actually deserve your time.

The full list

Alphabetically, for fairness:

Bluesky, Discord, Facebook, Google Business Profile, Instagram, LinkedIn, Mastodon, Pinterest, Reddit, Snapchat, Telegram, Threads, TikTok, X (formerly Twitter), YouTube.

(That's actually fifteen. We say "fourteen" because Discord and Telegram are messaging-first; most authors who use them aren't using them the way they use Instagram. But the scheduler handles all of them. Substack is notably absent — their API isn't open to third-party schedulers yet.)

What each one is actually for (for authors)

Instagram — Still the default for most fiction authors. Strong for book aesthetics, cover reveals, carousel quote cards, reels with your voice or an audio trend. Readers treat it as the gallery of your author life.

TikTok — The biggest new-reader funnel in fiction right now. BookTok exists and it works. Short video, 15–60 seconds, good for a recurring character bit, a scene reaction, a "if you liked X read Y" list. Higher effort than Instagram posts; disproportionate reward when you hit.

YouTube — Two flavors. YouTube Shorts (vertical video) is basically a second home for your TikToks. Long-form YouTube (writing vlogs, craft deep-dives, cover-reveal walkthroughs) is a different commitment — great for authors who genuinely like being on camera for 10+ minutes at a time.

Threads — Meta's answer to X. Native Instagram audience. Conversational, text-first. Works well for behind-the-scenes micro-thoughts. Lower effort than any other platform; rewards are growing slowly but steadily.

X (Twitter) — Still where the industry-insiders talk. If you care about agents, editors, book reviewers, and the writing community conversation, you're there. If you care about readers, it's a secondary channel at best. Don't quit if you're already there; don't start if you aren't.

Bluesky — X's most likely replacement for the book-writer community. Smaller now, higher signal, no algorithmic shenanigans. If X is where you live, Bluesky is where you probably also want to be.

Facebook — Pages only in this tool (Groups aren't supported by the Facebook API we can use). Author Pages are rough for organic reach — Meta hid them years ago. Facebook reader-community groups are thriving, but you'll post to those from inside Facebook directly rather than via the scheduler. If your author Page is already active, schedule to it here; if you're starting from zero, don't pour effort in.

LinkedIn — Yes, really, for non-fiction authors and for authors of business-adjacent fiction (thrillers, corporate-world mysteries, entrepreneur memoirs). If you write cozy mysteries set in a bakery, skip it.

Pinterest — Criminally underused by fiction authors. Works as a long-tail search engine: a pin from 2023 can still be driving pre-orders in 2026. Vertical images of book covers, aesthetic boards by series, character inspiration boards. Set-it-and-forget-it works better here than anywhere else.

Substack (not supported) — Substack's API isn't open to third-party schedulers for either Notes or newsletter posting. Keep writing newsletters in Substack directly; use this tool for everywhere else. We'll add Substack support the day they open their API, which is not today.

Reddit — Tricky. r/romancebooks, r/Fantasy, r/cozymystery and similar communities are real. They also have strict self-promotion rules. Author Automations Social schedules posts; it can't protect you from a mod banning you for spamming. Use sparingly and only in subs where you're already an active member.

Pinterest, Threads, TikTok, Reels — the four places where being visually distinctive pays the most right now.

Telegram — Channels for superfans. If you have a backchannel with your dedicated readers and you're announcing pre-orders to them, this is where you do it. Not a discovery tool.

Discord — Servers for even-more-dedicated superfans. Same story as Telegram with a younger skew. Works for authors with active fandoms.

Mastodon — A smaller X-alternative. Most authors I know either use Bluesky instead or both alongside X. If you're already on Mastodon you know why; if you're not, skip.

Snapchat — Basically irrelevant for fiction authors in 2026. We support it so nobody comes at me for forgetting it, but I wouldn't build a strategy around it.

Google Business Profile — Mostly relevant for authors with a physical-location business (indie bookstore owners, writing retreats, conference organizers). Not a general-purpose author tool.

The strategic point

You don't need fourteen platforms. You need two or three where you're visible, engaged, and actually reaching readers — plus optionally one or two "set-it-and-forget-it" platforms that you cross-post to for long-tail discoverability.

How to pick yours

Ask yourself three questions:

1. Where are my readers? Romance, romantasy, and young adult lean hard into TikTok and Instagram. Cozy mystery tilts toward Facebook Pages and Instagram. Thrillers and literary fiction have meaningful pockets on X and Threads. Non-fiction depends entirely on your topic (business = LinkedIn; craft = YouTube; niche = Reddit).

2. What do I actually like making? If you hate video, don't build a strategy around TikTok. Seriously. Pinterest carousels are a real strategy. Threads text posts are a real strategy. Make what you can sustain.

3. What's already working? If you've been posting to Instagram for two years and it converts to sales, don't abandon it because TikTok is cool this quarter. Double down.

The three-platform rule of thumb

Most authors I coach settle at:

• One "primary" platform where they post 4–5 times a week with real effort
• One "secondary" platform where they cross-post or run a lightweight version (Threads is popular for this because it takes thirty seconds)
• One "long-tail" platform (usually Pinterest) where posts go to work for years

That's three platforms. That's the right number for most authors.

Pay the full attention to your primary. Half-attention to your secondary. And schedule-and-forget on your long-tail.

What Author Automations Social actually changes

The tool removes the punishing part of being on multiple platforms: logging in separately, posting in slightly-different formats, remembering what you said where, tracking what worked. You write once, pick your platforms, schedule, done.

That efficiency is the only reason most authors can credibly be on three platforms at all. Without a scheduler, "three platforms" is a part-time job. With one, it's twenty minutes twice a week.

What to do next

Figure out your primary, secondary, and long-tail. Then:

• Connect your first platform in 30 minutes so there's something real to work with
• Read the TikTok-only campaign guide if TikTok is (or should be) your primary
• Read the carousel-only campaign guide if Instagram is your primary and carousels are your format

The best time to simplify your platforms is before you schedule 30 days of posts to six of them. The second best time is now.
