E-commerce Campaign Strategy
A Google Ads strategy built around your margins — not Google's defaults.
Campaign structure, budget allocation, ROAS targets, and scaling decisions for Indian e-commerce brands — planned before a single rupee is spent, so every campaign has a purpose and every product tier has a profitability target.

The core problem
Most e-commerce Google Ads accounts have campaigns but no strategy.
There is a difference between having campaigns running and having a strategy. A strategy means every campaign exists for a reason, every product tier has a margin-appropriate ROAS target, budget flows toward what is profitable, and there is a documented plan for what happens when you want to scale from ₹1L to ₹5L to ₹20L per month.
✕ What I see in most accounts
One Shopping campaign with all products grouped together — bestsellers and dead stock getting equal budget.
A single tROAS target applied to the whole account, regardless of which products have 15% margins and which have 55%.
PMax running without brand exclusions, silently absorbing brand search queries and inflating its own ROAS numbers.
No documented plan for what to do when the client says "I want to double my budget next month."
✓ What a strategy-driven account looks like
Products segmented into margin tiers with custom labels — each tier has its own campaign and its own ROAS target derived from actual gross margins.
Shopping, PMax, brand Search, non-brand Search, and retargeting each have a defined role, budget share, and performance expectation.
Brand exclusions active on PMax. Search term reports reviewed weekly. Cannibalisation monitored monthly.

The framework
Six pillars of a profitable e-commerce Google Ads strategy.
Every strategy I build for an e-commerce client is structured around these six pillars. They are sequential — each one depends on the one before it. Skip a pillar and the account will eventually plateau or leak budget without anyone noticing.
Margin Mapping & Break-Even ROAS
Before I touch Google Ads, I need your product-level gross margin data. Not your average margin across the catalogue — your margin per product tier, after COGS, return rates, packaging, and shipping are subtracted. This is the number that determines every bidding decision.
The formula is straightforward: Break-even ROAS = 1 ÷ gross margin. A product with a 40% gross margin breaks even at 2.5× ROAS. A product with a 20% margin needs 5× just to cover costs — and that is before the management fee, platform fees, or any profit target.
I calculate this for every product tier and use it to set tROAS targets per campaign. This is the single most important step in the strategy, and most agencies skip it entirely because it requires the client to share real financial data instead of just granting Google Ads access.
Product Tier Segmentation
Once margins are mapped, I segment the entire product catalogue into tiers using custom labels in the Merchant Center feed. The segmentation drives campaign structure — each tier gets its own campaign with its own budget, ROAS target, and bid strategy.
Tier 1 — Hero Products
High margin, high sales velocity. These get the largest budget share and the most aggressive tROAS target. They are the growth engine of the account.
Tier 2 — Steady Movers
Moderate margin, consistent demand. Adequate budget with a tROAS target set slightly above break-even. These sustain revenue between spikes.
Tier 3 — Low Margin / Long Tail
Low margin or slow-moving SKUs. Capped budget, high tROAS target to prevent overspend. Some products here may be excluded from paid altogether.
Tier 4 — Excluded
Out-of-stock, seasonal (off-season), negative margin after ad cost, or products with zero conversion history. Excluded from all campaigns to protect budget.
Campaign Architecture & Role Assignment
Every campaign in the account has a defined role. This prevents overlap, budget cannibalisation, and the common situation where three campaign types all chase the same high-intent buyer while ignoring the rest of the funnel.
| Campaign Type | Role | Budget Share | Primary Metric |
|---|---|---|---|
| Standard Shopping | Product-specific intent capture | 30–40% | ROAS per product tier |
| Performance Max | Cross-channel scale & discovery | 25–35% | ROAS (brand-excluded) |
| Brand Search | Branded query defence | 5–10% | Impression share, low CPC |
| Non-Brand Search | Category & competitor capture | 10–20% | CPA / assisted ROAS |
| Display Retargeting | Cart abandoner & visitor re-engagement | 5–10% | View-through + click ROAS |
Budget shares are starting points — adjusted monthly based on actual performance data.
Budget Allocation & Pacing
Budget allocation is not about splitting your monthly spend equally across campaigns. It is about directing money toward the campaigns and product tiers that generate the most profitable revenue per rupee spent — and reducing allocation where diminishing returns start.
I set daily budgets per campaign based on the role each campaign plays and the conversion volume it needs to exit Smart Bidding's learning phase. A campaign that gets fewer than 15 conversions in 30 days does not have enough data for tROAS to work — so it either gets consolidated with another campaign or given a higher budget temporarily to build signal.
Budget pacing is checked weekly, not monthly. If a hero product campaign is hitting its tROAS target consistently by mid-month, that is a signal to increase its budget — not wait until the next planning cycle. Conversely, if a campaign is spending aggressively but ROAS is declining, budget gets pulled back before it wastes the rest of the month's allocation.
Scaling Roadmap
Scaling is the question every e-commerce founder asks within the first month: "Can we spend more?" The answer depends on whether the current account structure can absorb more budget without degrading efficiency.
There are three ways to scale a Google Ads e-commerce account, and most agencies only attempt the first one:
Vertical scaling — increase budget on existing winners
Raise daily budget on campaigns already hitting ROAS targets. Simple, but hits diminishing returns fast. A campaign spending ₹1L at 6× ROAS will not spend ₹3L at 6× — it might do 4.5×. The question is whether 4.5× is still above your break-even ROAS.
Horizontal scaling — add new campaign types or surfaces
Add non-brand Search alongside Shopping. Layer YouTube retargeting on top of Display. Launch a second PMax campaign targeting a different product category. This increases total addressable demand without oversaturating existing campaigns.
Catalogue scaling — add more products to the paid mix
If Tier 1 products are maxed out, evaluate Tier 2 products with strong enough margins. Or launch new product lines with dedicated campaign budgets. This is the most sustainable long-term scale lever.
The strategy document I deliver to every client includes a scaling matrix: for each budget level (₹1L, ₹3L, ₹5L, ₹10L+), it specifies which campaigns absorb the incremental spend, what the expected ROAS range is at that level, and what needs to change in account structure before the increase happens.
Seasonal & Promotional Planning
Indian e-commerce has sharp seasonal peaks — Diwali, Big Billion Days, Republic Day sales, end-of-season clearances — and the brands that plan 4–6 weeks ahead capture disproportionate revenue during these windows. The ones that react the week before get outbid on every keyword.
My seasonal strategy covers four phases: pre-season audience building (remarketing lists loaded with recent visitors, customer match lists refreshed), budget pre-loading (budgets increased 2–3 weeks before the peak so Smart Bidding has time to re-learn at higher spend), peak execution (tROAS targets loosened slightly to let Smart Bidding spend aggressively during the 3–7 day window), and post-season tapering (budgets reduced systematically over 2 weeks, not cut overnight).
I also manage the promotions feed during sale periods — updating sale prices, adding promotional text badges to Shopping listings, and ensuring Merchant Center reflects the correct promotion dates. A Shopping listing with a "Sale" badge gets 15–25% higher CTR than the same listing without one.
Budget benchmarks
How much should an Indian e-commerce brand spend on Google Ads?
There is no single correct answer, but there are thresholds below which certain campaign types simply do not have enough data to function. Here is what I recommend based on managing e-commerce accounts from ₹50K to ₹30L per month.
Starting Out
₹50K – ₹1L/mo
Focus on Standard Shopping for your top 20–30 products. One campaign, margin-based tROAS. Brand Search to protect branded queries. No PMax yet — not enough conversion volume for it to learn effectively.
Typical structure: 2 campaigns
Growth Phase
₹1L – ₹5L/mo
Full architecture: Shopping segmented by margin tier, PMax with brand exclusions, brand Search, non-brand Search for category terms, and Display retargeting. This is where the strategy framework matters most.
Typical structure: 5–7 campaigns
Scale Phase
₹5L+/mo
Multi-campaign architecture with separate PMax campaigns per product category, YouTube for mid-funnel nurture, aggressive non-brand Search expansion, and testing budgets for new campaign types. Looker Studio dashboards become essential.
Typical structure: 10–15+ campaigns
I do not accept e-commerce accounts below ₹50,000/month ad spend — the data volume is too thin for Smart Bidding to work.
What goes wrong
5 Strategy Mistakes That Stall E-commerce Google Ads Growth
Scaling budget before fixing tracking
If your purchase conversion values are wrong — even by 10–15% — Smart Bidding optimises toward incorrect numbers. Doubling the budget doubles the scale of the error. I have seen accounts where the Google Ads conversion value was ₹3,200 per order but the actual average order value was ₹1,800. Every tROAS decision in that account was based on fiction.
Running PMax as the only campaign type
PMax is powerful but opaque. When it is your only campaign, you cannot tell what is working — whether performance comes from Shopping, Search, Display, or YouTube. If ROAS drops, there is no lever to pull because everything is bundled. Running Shopping alongside PMax gives you a control group and visibility into what PMax is actually contributing.
Ignoring the feed while optimising campaigns
Campaign settings account for maybe 30% of Shopping and PMax performance. The feed accounts for the other 70%. An agency that spends hours adjusting bids but never optimises product titles, fixes missing GTINs, or adds custom labels for margin tiers is optimising the wrong part of the system.
Using the same ROAS target for all products
A 4× tROAS target across the whole catalogue means your 55% margin products are underleveraged (they could be profitable at 2.5×) and your 18% margin products are overspending (they need 6× to break even). This single-target approach is the most common strategic error I see — and it is the easiest to fix with product tier segmentation.
No plan for when ROAS plateaus
Every account hits a performance ceiling eventually. Without a strategy that anticipates this — and has documented next steps like horizontal scaling, catalogue expansion, or landing page testing — the response is either panic budget cuts or blind budget increases. Both waste money. The scaling roadmap eliminates this by prescribing what to do at every plateau point.

Common questions
E-commerce Strategy FAQ
Do I need a strategy session before you start managing my ads?
Yes — strategy is built into the onboarding, not charged separately. Before any campaign goes live, I do the margin mapping, product tier segmentation, campaign architecture planning, and budget allocation. This happens in the first 5–7 days and is part of every management engagement. You approve the strategy before anything launches.
Can you build a strategy for my team to execute without managing the account?
Yes, this falls under my consulting offering. I will do the full strategy — margin analysis, product segmentation, campaign architecture, budget allocation, and scaling roadmap — and deliver it as a documented plan your in-house team or agency can implement. I also offer follow-up strategy calls to course-correct based on initial results.
How often does the strategy get updated?
Campaign tactics are adjusted weekly based on performance data — search term reviews, budget reallocation, bid adjustments. The overall strategy is reviewed quarterly: product tier assignments may change as new products launch or margins shift, budget allocation is rebalanced, and the scaling roadmap is updated. Major seasonal events (Diwali, Big Billion Days) trigger their own planning cycle 4–6 weeks before the peak.
What data do you need from me to build the strategy?
Product-level gross margins (or at least margin ranges per product category), current monthly ad spend and revenue, Google Ads account access (read-only for audit, then manager access for implementation), Google Analytics 4 access, and Merchant Center access. If you do not have exact margins per SKU, category-level margins work as a starting point — we refine as we go.
My current agency says they already have a strategy. How do I know if it is working?
Ask them three questions: What is the break-even ROAS for your top-selling product category? What percentage of your PMax conversions come from brand queries? At what monthly spend level will you hit diminishing returns? If they cannot answer these from memory, the strategy is either missing or superficial. A free audit from me will give you an independent assessment of what your current account structure is actually doing.
