Amazon, Flipkart or your own website: how D2C brands should split ad budget

For most Indian D2C brands, the question isn't whether to sell on Amazon and Flipkart or on your own website. It's how to balance them. Each channel has different economics, different customer relationships and different advertising mechanics, and your ad budget should reflect that. Here's a practical way to think about the split.

How the channels differ

	Your website (e.g. Shopify)	Amazon & Flipkart
Customer data	You own it	Mostly the marketplace's
Margin per order	Usually higher (no marketplace fees)	Lower after commissions and fees
Trust and convenience	You must earn it	Built in: reviews, delivery, returns
Conversion rate	Often lower	Often higher
Repeat purchase	You can drive it directly	Harder to influence
Main ad formats	Meta, Google, YouTube, influencers	Sponsored products, brands, display
RTO and COD risk	You manage it	Handled by the marketplace's processes

Neither is "better". Your website builds a brand and a customer base you own. Marketplaces bring ready demand and trust, at the cost of margin and data.

Why the channels affect each other

The biggest planning mistake is treating them as separate businesses. Your Meta and YouTube ads don't only drive website sales. Many people who see your ad go and search for your brand on Amazon, where they already have an account, saved addresses and Prime delivery.

The result:

• website-only reporting undercounts what your social and video ads achieve;
• marketplace ads often capture demand your other ads created;
• cutting brand-building spend can quietly reduce marketplace sales weeks later.

That's why the split should be planned from one budget and judged on total business results, not each channel's own dashboard.

Advertising on marketplaces

Marketplace ads work much like search ads: shoppers are searching for products, and you bid to appear.

• Sponsored product ads show individual products in search results and on product pages. They're the core format, and the closest thing to Amazon PPC most brands run.
• Sponsored brand ads feature your logo and several products, useful for brand searches and category presence.
• Display ads reach shoppers on and off the marketplace based on browsing and purchase behaviour.

Good marketplace advertising starts with the basics: strong product listings, good images, competitive pricing, enough reviews and stock availability. Ads amplify a good listing. They can't fix a weak one.

Measure marketplace ads on advertising cost of sales (ACoS) or ROAS, and on total sales growth, including organic ranking improvements that ads help create.

Advertising for your website

Website growth usually relies on demand-creating channels:

• Meta for creative-led prospecting and retargeting. See our account structure guide.
• Google Search, Shopping and Performance Max for branded and category intent.
• YouTube and influencers for awareness and consideration.

Judge website advertising on RTO-adjusted ROAS, new-customer acquisition and contribution margin, because RTO and COD costs fall on you rather than the marketplace.

A practical way to split budget

Rather than starting with fixed percentages, follow these steps:

1. Fix your unit economics per channel. Work out contribution margin per order for your website and each marketplace, after product cost, fees, shipping and returns.
2. Fund marketplace basics. Cover brand-defence and core product sponsored ads so competitors don't take your branded searches.
3. Fund website demand creation. Invest in Meta, Google and creative to acquire customers you own, at a cost below their expected lifetime value.
4. Watch the interaction. When you increase social spend, does marketplace brand search and sales rise too? Track it monthly.
5. Rebalance on total contribution margin. Shift budget towards whichever mix produces the most total profit, not the best single-channel ROAS.

Brands with strong repeat purchase and higher website margins often lean towards website growth over time. Brands in highly searched categories, or with lower repeat rates, may keep marketplaces as their main engine.

Measuring the whole picture

A few metrics help you see across channels:

• Total revenue and contribution margin across all channels, weekly.
• Marketing efficiency ratio (MER): total revenue divided by total ad spend across all channels.
• New customers by channel and the share of revenue from returning customers.
• Branded search volume on Google and on marketplaces, as a signal of demand you're creating.
• Marketplace organic rank for key products, which ads and sales velocity help improve.

Our attribution guide explains how to set up a practical measurement model.

Common mistakes

• Judging Meta only on website ROAS and cutting it, then watching marketplace sales slide.
• Running marketplace ads on poor listings, so traffic doesn't convert.
• Letting channels compete on price in ways that erode the brand and margins.
• Ignoring stock-outs. Ads on out-of-stock items waste budget and hurt ranking.
• Treating marketplace customers as lost. Packaging inserts, brand registry features and great products can still encourage future purchases.

Frequently asked questions

Should a new brand start on marketplaces or its own website?

Many start on marketplaces for trust and ready demand, while building a website for brand, margins and customer data. The right balance depends on category, price point and how much you can invest in demand creation.

Is Flipkart worth it if we're already on Amazon?

Often yes. The two marketplaces reach overlapping but different audiences, especially across regions and price segments. Test with your core products and measure incremental sales.

Who should manage marketplace ads?

Ideally the same team that plans your other channels, or one working closely with it, so budgets and messages are coordinated.

A worked example of the interaction

Imagine a brand that sells through its website and Amazon, and cuts Meta spend by a third to "improve ROAS". These figures are illustrative:

	Before the cut	Four weeks after
Meta spend	₹6,00,000	₹4,00,000
Website revenue	₹18,00,000	₹13,50,000
Website ROAS (Meta)	3.0×	3.4×
Amazon revenue	₹22,00,000	₹18,50,000
Total revenue	₹40,00,000	₹32,00,000

Website ROAS improved, which looks like a win on the Meta dashboard. But total revenue fell by ₹8 L, much of it on Amazon, where shoppers had been searching for the brand after seeing its ads. Measured on the whole business, the cut probably cost more than it saved. Only total revenue and margin across channels show this.

Planning a monthly review

Once a month, put all channels in one view: spend, revenue, contribution margin and new customers for your website, Amazon and Flipkart. Agree one or two budget moves, note the expected effect, and check next month whether it happened. Over a few quarters, this builds a clear picture of how your channels work together.
