Digital Products — Every Idea

The evidence

Live market data + the 3-layer review

Pulled live from Gumroad's search API + Flippa + the FB Ad Library (3 Jul 2026). Review counts are a sales proxy (real sales are multiples higher); "market" = number of competing products.

Signal	What we found
🟢 Wide-open fleet niches	Menopause 140 products (top seller 5 reviews) · Mortgage 66 · Home-reno 79 · Grant 316 — near-empty, and we own the traffic.
🟡 Proven paid winner	"Niche-OS" pattern — Acadashboard (Notion Student OS) £18.69 × 4,509 reviews. One template, one audience.
🔴 Saturated / avoid	Generic Notion (19,695), procreate brushes (10,751), pet portraits, kids' books, weight-loss, manifestation — burned on Meta ads.
🟣 Underground survivor	Esoteric/spiritual — Mind & Magick: £97 × 163 reviews (~£16k floor) on one SKU, all art + content, no craft barrier.

The 3-layer filter (how we found the underground pick)

① Gumroad — real off-market money is VRChat/Blender/music (craft-heavy, skip); survivor that fits us is esoteric/spiritual.
② FB Ad Library — kills burned auctions; caught the trap (TTRPG/dev-tools empty on Meta only because buyers aren't there); green-field + reachable = tarot/witchcraft printables + digital wall art.
③ Flippa — quiet money is niche visual printable shops (~100% margin) + the PLR/resell-rights wildcard.

Where it all points

The verdict — a branded occult / tarot shop

Across all the data, one idea scored on every axis: proven revenue (Gumroad), green-field on Meta with a reachable audience (Ad Library), a visual printable shop (Flippa) — and it's pure AI-image work, our cheap-and-fast edge and everyone else's slow, expensive part.

The pick → a branded occult / tarot digital shop. Not one product — a small brand (the Mind & Magick model, rebuilt with better art + real ad/SEO muscle). Proven underground, soft on Meta, emotional identity-driven buyer, and the whole product is imagery we generate in minutes. So we did — scroll down.

Built, not described

The prototype — “MOTH & MOON”

Everything below was generated in one sitting with our AI image pipeline — a dark celestial-botanical tarot deck + matching printable grimoire + a ready-to-run ad. This is the exact quality that would go live.

The Moon · XVIII

The Star · XVII

The High Priestess · II

Printable “Book of Shadows” page — a second SKU type

A ready-to-run Instagram/FB ad creative — the scroll-stopper

Why it matters: five cohesive, sellable assets — three cards, a printable page, a finished ad — at near-zero cost in minutes. A normal seller pays an illustrator weeks and hundreds of pounds. That gap is the whole business.

£9

Printable pack

Ritual/moon-phase pages — the ad tripwire.

£19

Grimoire set

30–40 page printable journal.

£29

78-card deck

Instant digital, print-at-home. Hero product.

£45

Complete bundle

Deck + grimoire + guidebook. AOV lifter.

How we'd sell it

Etsy

Organic spiritual buyers already searching. Never the only leg (AI-content rules).

Own store + Meta ads

Soft auction, no compliance minefield. The ad above is the hook.

★ SEO funnel (the unfair move)

A 5-page site ranking "free printable book of shadows" → funnels free organic buyers in. No normal seller can do this.

Retarget + email

Capture on the freebie, retarget buyers with the bundle.

Risks: Etsy's AI-content policy (hence own-store second leg); keep copy aesthetic/identity-led not "manifest £10k"; validate the aesthetic converts on a small ad test before drawing all 78 cards.

Next step: finish a starter set (~10 cards + grimoire + freebie) → one-page store + Etsy listing → £30 of Meta ads with the creative above → read CTR + cost-per-sale. Converts → complete the deck; doesn't → swap aesthetic (celestial/botanical/gothic), same engine, or pivot to the wall-art runner-up.

Digital products — every idea, one page

The bottom line — three moves
