The ranked list
1. Referrals (past clients) — near-zero cost, highest LTV. Every gallery delivery should prompt a referral ask.
2. SEO (organic Google) — 6–18 month ramp, then compounds. Best for geographically-bound specialties.
3. Photography marketplaces — Chromafolio, Thumbtack, The Knot. Pay-per-lead or subscription. Predictable volume; variable quality.
4. Vendor partnerships — wedding planners, venues, florists. Quality referrals but relationship-dependent.
5. Instagram organic — still works for aesthetic specialties (weddings, brand, newborn). Declining for commercial.
6. Google Local Services ads — high-intent but limited to certain cities and categories.
7. Facebook/Instagram paid ads — volatile CPA; works if creative is strong.
8. TikTok organic — high growth ceiling for younger-audience specialties.
9. Pinterest — evergreen for weddings and boudoir.
10. Cold outreach — corporate/brand only; LinkedIn DMs still convert.
