Step-by-step in London
- Step 01
Week 1 — Build a credible landing page
Single Shopify or Webflow page with hero, founder story, 3 product proofs, pre-order CTA at ₹X with ₹500 deposit. Indian visitors trust founder faces — include yours.
- Step 02
Week 2 — Drive ₹25k of qualified traffic
Meta ads to lookalike audiences from comparable brand pages, ₹2,000/day for 7 days. Target ₹4–₹8 CPM, ₹15–₹30 CPC, 0.8–2% landing-to-deposit conversion.
- Step 03
Week 3 — Measure willingness-to-pay signals
Track: pre-order count, refund-request rate, organic shares, repeat-visitor rate, cart-add-to-deposit conversion. If under 30 deposits in week 3, kill or pivot the SKU.
- Step 04
Week 4 — Decide manufacture or kill
Threshold: 50 deposits in 21 days at full price → manufacture 500 units. 25–49 → iterate offer/messaging, retest. Below 25 → kill the SKU, save the inventory capital.
What goes wrong in London
- Trying to skip stages — playbooks compound; out-of-order execution leaves earlier-stage work undone and the later steps don't catch.
- Optimising the wrong leading indicator — picking a vanity metric (impressions, reach, follower count) instead of the playbook's actual primary KPI.
- Running the playbook against a broken funnel — the playbook ships traffic / leads / activity to a leaky landing page or onboarding, amplifying the leak.
- Hiring junior-only execution and expecting senior judgement — the playbook lists tactics; the calls between tactics need a senior operator.
- Cutting the playbook on a single bad month — compounding plays need quarterly review windows; monthly noise will kill the program prematurely.
What to track for London
- Time-to-first-signal — how long until you see the leading indicator move (typically 2-4 weeks for paid, 4-9 months for organic).
- Step-completion rate — what percentage of the playbook is actually shipped vs documented.
- Cost per primary outcome — CAC for acquisition playbooks, CPL for lead-gen, revenue-per-customer for retention.
- Velocity — how many full playbook cycles you complete per quarter.

Frequently asked questions
What if my category is too niche for paid traffic?
Run influencer seeding with 30 micro-creators in your niche. If 8+ post organically and you get 20+ deposits attributed to them, it's validation enough. We've used this for premium pet food and ayurvedic supplements.
Should I refund deposits if I don't manufacture?
Yes, immediately and without friction. Indian buyers remember brands that respect their money. Many of those refund recipients become customers when you launch the next SKU.

How long does this playbook take end-to-end?
The named-step durations are listed inline; total elapsed time depends on how many steps run in parallel. A typical sequential execution takes 16-24 weeks; parallel execution compresses that by 30-50%.
Can we run this in-house or do we need an agency?
In-house works when you have the seniority + bandwidth on the named-step disciplines. Most teams that try in-house solo end up doing 60-70% of the work and missing the cross-step optimisation. An agency or fractional senior compresses time-to-result by 30-50% on average.
What's the minimum budget to start?
Budget breaks into three lines: agency fee (if applicable), media spend, and tools. The combined minimum to make data-driven decisions in 2026 is ₹1L/month for paid-heavy playbooks. Below that, manual optimisation in-house is more honest than an agency retainer.
When do we stop and reassess?
Quarterly. Each quarter, review the leading indicator (movement) and the lagging indicator (outcome). If both are positive: scale. If leading is positive but lagging isn't: wait one more quarter. If leading is negative: change the playbook, not just the spend.
Does this playbook work outside India / outside the listed market?
The framework transfers; the specifics (CPCs, channels, compliance, language overlays) need adapting. The named steps are universal; the within-step tactics adapt to the local market.
