how to run performance marketing for ecommerce brands during Indian festive sales Diwali and Big Billion Days guide | This comprehensive guide, updated on October 11, 2026, from the Adyogi Editorial Team, provides a beginner-friendly approach to how to run performance marketing for ecommerce brands during Indian festive sales, specifically Diwali and Big Billion Days. It outlines a strategy requiring 6-8 weeks of active campaign management to maximize results.

What You'll Learn

Diwali and Flipkart's Big Billion Days represent the highest-stakes selling window on the Indian retail calendar. This guide shows you how to capture that opportunity, whether you manage a single D2C brand, a marketplace seller account, or a portfolio of client accounts at an agency, moving beyond guesswork into a repeatable, data-driven system.

• How to structure a phase-by-phase festive media calendar, starting 6-8 weeks before Diwali.
• How to split budget across Meta, Google, and marketplace ads as CPMs and CPCs spike.
• How to protect ROAS when auction costs rise 20-100% during peak festive weeks.
• How to retarget and retain festive shoppers after Diwali and Big Billion Days conclude.

Prerequisites: an active Meta Ads and Google Ads account, a product catalog connected to a feed, and at least one prior sales cycle of historical conversion data to benchmark against.

Why Festive Performance Marketing Matters in 2026

India's festive e-commerce economy is the single biggest revenue window of the year. Redseer projected festive 2025 e-commerce GMV to cross Rs. 1,15,000 crore (US$ 13.12 billion), with the first 11 days alone delivering more than INR 60K Cr. GMV, nearly 3.5 times business-as-usual levels. For 2026, Datum Intelligence expects online festive sales of ₹1.50-1.55 lakh crore, up 25-29% from 2025.

The catch: everyone bids in the same auction simultaneously. Meta CPMs run roughly ₹80-150 in normal periods versus ₹150-300 during festive season, a 60-100% increase, while Google Search CPCs move from roughly ₹8-15 up to ₹15-30. However, conversion intent rises sharply during festive periods, with conversion rates and cost-per-purchase both improving compared to normal periods. Festive digital ad spend is projected to corner over half of total media budget allocations, up from roughly 45 percent the year before. Diwali 2026 falls on Sunday, 8 November 2026, giving brands roughly four to six weeks from early October to build, test, and scale.

Bottom line: Early planning and strategic campaign management are crucial for capturing high-value sales during this largest e-commerce revenue window.

The Process at a Glance

Total time: approximately 6-8 weeks of active management, starting in early October and running through late November.

Step 1: Audit Last Year's Performance and Set Festive KPIs

What You're Doing

You're establishing realistic cost and conversion benchmarks by pulling last year's festive-period data. This removes guesswork from mid-sale budget decisions and keeps your team disciplined when panic sets in during peak weeks.

How to Do It

1. Export CPM, CPC, conversion rate, and ROAS from the same festive window last year across Meta Ads Manager and Google Ads.
2. Compare those numbers against normal-period baselines. Expect Meta CPMs to run roughly ₹80-150 in normal periods versus ₹150-300 during festive season, a 60-100% increase, and Google Search CPCs to move from roughly ₹8-15 up to ₹15-30.
3. Set a festive CPA ceiling and a minimum ROAS target per product category.
4. Flag your top 10 SKUs by historical festive velocity; these will get priority budget and creative.

Best Practices

• Build category-level benchmarks, since fashion, electronics, and jewelry inflate at different rates during peak weeks.
• Document a "walk-away" CPA per category so no one overspends mid-sale.

What Done Looks Like

You have a one-page benchmark sheet with target CPA, ROAS, and budget ceilings per category, signed off before any festive campaign goes live.

Step 2: Build and Warm Audiences Before the Festive Rush

What You're Doing

You're filling your retargeting pools while CPMs are still affordable. This is the difference between spending on people who know your brand versus chasing cold traffic during the most expensive auction of the year.

How to Do It

1. Start awareness and traffic campaigns four to six weeks out. Starting in early October prevents Diwali week from being cold and expensive.
2. Run top-of-funnel video and carousel ads on Meta to build custom audiences from video views, site visitors, and add-to-cart events.
3. Grow first-party channels in parallel: WhatsApp broadcast lists, email subscribers, and Google Business Profile updates.
4. Set up Google Ads seasonality adjustments ahead of your sale dates; these adjustments work with Performance Max, Search, and Shopping campaigns on target ROAS or target CPA bidding.

Common Mistakes

Mistake: Waiting until the week of Diwali to launch any ads. Why it's costly: If you only switch on in the last week, you're paying peak auction prices to reach cold users who've never heard of you.

What Done Looks Like

By mid-October you have a retargeting audience at least 3-5x larger than your normal baseline, built from the last 30 days of warm traffic.

Step 3: Launch Festive Campaigns Across Meta, Google, and Marketplaces

What You're Doing

You're activating your sale offers, product feeds, and creative in mid-October, ahead of the Dhanteras-to-Diwali peak. Early-bird shoppers are already in the market, and you want visibility before costs spike further.

How to Do It

1. Publish festive-specific creative with gifting angles, bundle offers, and countdown messaging. Limited-time festive offers and countdown timers are proven tactics for fashion and retail sites running Diwali Super Sale campaigns.
2. Split spend so Meta drives discovery and retargeting while Google captures high-intent search and Shopping.
3. If you sell on Amazon or Flipkart, sync your marketplace ad campaigns with your D2C site campaigns so messaging and pricing stay consistent across channels.
4. For multi-channel accounts managing Facebook, Google, and Amazon simultaneously, a platform like Adyogi can centralize budget pacing, bid automation, and catalog sync so campaigns don't drift out of alignment during the busiest weeks of the year.

Example

What Done Looks Like

All festive offers, feeds, and creative are live and indexed at least 10-14 days before Dhanteras, with no last-minute delays.

Step 4: Scale Budgets Through the Dhanteras-to-Diwali Peak Window

What You're Doing

You're shifting budget toward your best-performing campaigns and products as buying intent peaks around Dhanteras and Diwali week, moving from testing into full-throttle conversion mode.

How to Do It

1. Increase budgets on proven top performers; lift budgets 1.5 to 2x in the two weeks before Dhanteras.
2. Shift creative toward gifting and urgency messaging. During peak week, prioritize retargeting cart-abandoners with dynamic ads showing the exact product they viewed.
3. Monitor CPA hourly during the first 48 hours of Big Billion Days. The first 11 days of the 2025 sales event alone clocked more than INR 60K Cr. GMV, nearly 3.5 times business-as-usual levels, meaning traffic and auction competition surge fast.
4. Keep your walk-away CPA ceiling from Step 1 visible to whoever is pacing budgets live, so scaling decisions stay disciplined under pressure.

Best Practices

• Concentrate incremental budget on the 20% of SKUs driving 80% of festive conversions.
• Keep a small always-on budget on prospecting even during peak days, so your retargeting pool doesn't run dry.

What Done Looks Like

Your top campaigns are spending 1.5-2x their pre-season daily budget while ROAS stays within 10-15% of your Step 1 target.

Step 5: Retarget and Retain Festive Shoppers After Diwali

What You're Doing

The sale ends, but your revenue opportunity doesn't. You're converting one-time festive buyers into repeat customers and capturing spillover demand into the wedding and year-end season.

How to Do It

1. Launch thank-you and review-request flows within 48 hours of delivery to capture social proof while purchase intent is fresh.
2. Build post-festive retargeting segments from festive purchasers, excluding them from prospecting and instead serving cross-sell or replenishment offers.
3. Reallocate a portion of festive budget into loyalty and VIP campaigns. Loyalty-driven tactics like early access, VIP-only deals, and member gift coupons help activate high-value segments after the initial rush, improving customer LTV.
4. Review full-funnel data from the entire festive window and feed it back into next year's Step 1 benchmark sheet.

What Done Looks Like

You have a documented post-festive retention campaign running, a review-collection flow live, and a complete performance report ready to inform next year's festive planning.

What to Do After Running Your Festive Campaigns

Phase 1 (Weeks 1-2 post-Diwali): Reconcile actual spend versus the Step 1 benchmark sheet, calculate blended ROAS across all channels, and identify which SKUs and creative formats overperformed.

Phase 2 (Weeks 3-6): Shift surviving festive creative into a wedding-season or year-end campaign, since Indian festive demand historically bleeds into extended gifting through December.

Phase 3 (Ongoing): Build a living festive playbook documenting what worked, update your audience-warming timeline for next year, and if managing multiple channels became a bottleneck, evaluate an omnichannel management partner before the next festive cycle.

Common Plateaus and How to Break Through

ROAS Drops Sharply in the First Week of the Sale

Likely cause: Everyone enters the auction simultaneously, pushing CPMs and CPCs up. Festive CPMs and CPCs climb roughly 20 to 60 percent through peak weeks while your bids and budgets stay at pre-season levels.

Fix: Raise target ROAS or CPA ceilings slightly going into peak week rather than keeping rigid pre-season bid caps, and lean harder on warmed retargeting audiences, which convert cheaper than cold prospecting during the surge.

Retargeting Pool Feels Too Small on Peak Days

Likely cause: Audience-warming campaigns started too late or with too little budget in early October.

Fix: Commit 15-20% of total festive budget to a dedicated 3-4 week warming phase starting in early October, well before Dhanteras.

Creative Fatigues Fast During the Festive Window

Likely cause: Running the same static festive banner across the entire multi-week window while competitors rotate offers and urgency messaging.

Fix: Rotate creative weekly, using countdown timers and gifting angles early, shifting to urgency and last-chance messaging in final days. Flash sales and aggressive retargeting help maintain momentum, especially as Diwali approaches.

Managing Multiple Ad Channels Becomes Unmanageable at Scale

Likely cause: Manual budget pacing across Meta, Google, and multiple marketplaces during the highest-volume weeks leads to missed bid adjustments and stockout mismatches.

Fix: Centralize management through an omnichannel platform like Adyogi, which offers dedicated account managers, omnichannel support across Facebook, Google, and Amazon, and automation tools designed to drive maximum profitability during high-volume periods.

Conclusion

Successfully running performance marketing during Diwali and Big Billion Days comes down to disciplined sequencing: audit and set benchmarks early, warm audiences before the rush, launch offers ahead of peak pricing, scale budgets decisively during the conversion window, then retain what you've won. Brands that follow this approach consistently outperform those that scramble in the final week.

Key Takeaways

• A 6-8 week phased calendar, starting in early October, is the minimum runway needed to warm audiences before CPMs and CPCs spike 20-100%.
• Budget discipline matters more than budget size: category-level CPA ceilings set in advance prevent panic overspending during peak auction weeks.
• Next action: build your Step 1 benchmark sheet this week, using last year's festive data as the baseline for 2026 targets.

FAQ

How to run performance marketing for ecommerce brands?

Running performance marketing for ecommerce brands means setting measurable CPA and ROAS targets, building audiences across Meta and Google before peak demand hits, launching conversion-focused campaigns with synced product feeds, scaling budgets on proven winners during high-intent windows, and retargeting buyers afterward to drive repeat purchases. During Indian festive sales, this process compresses into a 6-8 week cycle around Dhanteras and Diwali, where auction costs rise sharply and timing becomes as important as budget size.

When should I start festive advertising for Diwali 2026?

You should start building and warming audiences four to six weeks before Diwali, which falls on Sunday, 8 November 2026, meaning early October is the ideal start window. Starting in early October prevents Diwali week from being cold and expensive.

How much do Meta and Google ad costs rise during Diwali and Big Billion Days?

Expect Meta CPMs and Google Search CPCs to climb roughly 20 to 60 percent through the peak festive weeks, with the sharpest jumps occurring in the ten days before Dhanteras and Diwali as every advertiser bids on the same audiences simultaneously.

What budget split works best between Meta, Google, and marketplace ads during festive sales?

A common structure allocates roughly 35-40% to Meta for discovery and catalogue retargeting, 35-40% to Google Search and Shopping for high-intent capture, and the remainder to marketplace ads on Amazon and Flipkart for in-platform visibility.

Should brands increase ad budgets during Big Billion Days even though costs rise?

Yes, because conversion rates and average order values also rise during this period, which can offset higher acquisition costs if campaigns are structured correctly and audiences are warmed in advance.

How do I retain customers acquired during Diwali and Big Billion Days after the sale ends?

Launch thank-you and review-request flows within 48 hours of delivery, build a dedicated post-purchase retargeting segment excluding festive buyers from prospecting campaigns, and reallocate part of your festive budget into loyalty or VIP offers to activate high-value repeat customers.

Is it worth using an ad management platform like Adyogi for festive season campaigns?

For brands managing multiple channels (Facebook, Google, and Amazon simultaneously) during the highest-volume weeks of the year, a platform can prevent missed bid adjustments and budget pacing errors. Adyogi offers omnichannel support, dedicated account managers, and automation built for multi-channel festive scaling.
