The niche matters more than the format. Faceless accounts don't fail because nobody sees a face — they fail because the subject was too broad to say anything specific about, or so saturated that being good wasn't enough to be noticed.
So before the list, the test. Then thirty ideas grouped by why they work, and four categories I'd avoid outright.
The test: can you write forty posts about it?
Not think of forty — write forty, each making a different point. Try it on paper for ten minutes before committing a year to something.
Most abandoned accounts fail this test at post nine and the owner finds out in month three. A subject that passes tends to have three properties: people are already asking questions about it, there's detail underneath the surface, and getting it wrong costs something. That last one is what makes people save a post.
Carousels have a particular bias here. They reward subjects with structure — steps, comparisons, numbers, mistakes, before-and-afters. If your idea is mostly a mood, it's a better fit for video than for slides.
Teach one narrow skill
The strongest category, because the ceiling is your knowledge rather than your reach. Narrow beats broad every time: "sourdough" is a saturated ocean, "sourdough in a domestic oven that doesn't hold heat" is a subject.
- Spreadsheet formulas for people who inherited a finance job
- Home espresso dialling-in — grind, dose, yield, one variable per post
- Sewing repairs that save a garment, not projects that make one
- Aquarium water chemistry, which is where the whole hobby goes wrong
- Manual-mode photography explained one setting at a time
- Houseplant diagnosis — what a specific leaf pattern actually means
- Knife sharpening by steel type
Know one category of things deeply
Purchase-adjacent, which makes it the easiest category to eventually earn from, and people arrive already wanting an answer.
- Mechanical keyboard switches compared by feel and noise
- Running shoes by foot shape and gait rather than by brand
- Cast iron, carbon steel and stainless — what each is actually for
- Budget audio gear that outperforms its price
- Second-hand tool buying: what to check, what to walk away from
- Office chairs under a real budget, including the ones to avoid
Own a place
Geography is the most underrated faceless moat there is. It's inherently narrow, it's hard for a stranger to fake, and the audience is worth more per follower than a general one because they can actually turn up.
- What a specific neighbourhood costs to live in, updated quarterly
- Walks within an hour of one city, graded by difficulty
- What opened and closed on one high street this month
- Council rules people in your area get fined for not knowing
- The local property market in numbers, monthly
Explain an industry from inside
If you already do a job, you have a subject most people find genuinely opaque — and this is the category where being faceless is a feature rather than a constraint.
- What things cost in your trade, and why quotes differ so wildly
- Contract clauses that regularly catch people out
- How a process actually works end to end — planning, conveyancing, claims
- Mistakes you watch clients make in week one
- What the jargon on your invoices means
Numbers, comparisons and decoding
Carousel-native by construction. A comparison has slides in it already, and posts of this shape get saved and sent on, which is the engagement that actually compounds.
- Real running costs of things people underestimate — EVs, pools, horses, freelancing
- Two ways of doing something, priced out honestly
- Label decoding: food, skincare, insurance documents
- "What this actually means" for a field of routine jargon
- Timelines — how long a process really takes versus the advertised figure
- Annual price changes in one category, tracked
- Common statistics in your field, sourced properly and corrected
Four I'd avoid
Named rather than padded into the count above, because entering these now is a bad trade.
- Motivational quotes. Infinitely supplied, zero moat, and an audience that follows the quote rather than the account.
- General "productivity" or "mindset". Too broad to pass the forty-post test without repeating yourself by week two.
- Reposted compilations. Someone else's work, a copyright complaint waiting to happen, and both feeds now demote content they can tell is unoriginal.
- Anything that needs your face to work. Reaction, personality, lifestyle. Going faceless is a real trade — take subjects that don't pay the cost.
Once you've picked one
Write the first forty in one sitting, in a list, before making a single graphic. It takes an hour and it tells you honestly whether the subject holds — and if it does, you'll never again open the app wondering what to post.
Then start slower than you want to. A new account posting six times a day looks exactly like what it looks like; one a day, building weekly is the ramp that works. If you want the reasoning on frequency generally, how often to post covers it, and carousel sizes has the dimensions for each platform.
The part that ends most faceless accounts isn't the idea — it's making the thing every day once the novelty has gone. SlideBuddy writes and publishes the carousels for you, around a subject you set, to Instagram, TikTok and Facebook. You keep the point of view and the last word on every post; it handles the production.
