Blog/Paid Media Strategy
Paid media for eCommerce — the full-funnel playbook that scales revenue.
eCommerce is the most competitive paid media vertical — but most brands losing are not being outspent, they are being out-structured. The winning brands separate new customer ROAS from returning customer ROAS, invest in feed quality as a performance lever, and measure contribution margin rather than celebrating a ROAS ratio that masks a losing economics. This playbook covers the full stack from channel selection to seasonal planning to the metrics that actually predict whether you can scale profitably.

“ROAS is a ratio, not a profit. I've seen accounts with 8x ROAS running at a loss because COGS + shipping + returns + fees made every 'profitable' sale a net negative. Know your margin before you celebrate your ROAS.”

The eCommerce paid media stack
Channel by channel — what each one does and how it fits.
| Channel | Funnel stage | Format | Primary metric |
|---|---|---|---|
| Google Search | Bottom funnel | Text ads, DSA | ROAS, conversion rate |
| Google Shopping / PMax | Bottom funnel | Product listings | ROAS, new customer ROAS |
| Meta Prospecting | Top funnel | Video, carousel, image | CPM, reach, new visitors |
| Meta Retargeting | Mid–bottom funnel | Catalog, DPA, video | ROAS, CVR, add-to-cart |
| TikTok | Top funnel | Native video | CPM, view rate, link CTR |
| YouTube | Mid funnel | In-stream video | View-through conversions, reach |
4–6x
blended ROAS is a healthy benchmark for established eCommerce brands — but calculate your break-even ROAS first. If your gross margin is 40%, you break even at 2.5x. Every point above that is real profit. Every point below is a loss.
The metrics that matter
The ROAS trap — and the metric separation that changes strategy.
The ROAS trap
Chasing high ROAS leads to pulling back top-of-funnel spend that feeds your retargeting pipeline. A brand that cuts Meta prospecting because 'it has low ROAS' will see Google retargeting ROAS drop 60 days later — because they ran out of warm audiences. Top-of-funnel ROAS is always lower. It is supposed to be. Do not cut it.
New customer ROAS vs returning customer ROAS
Returning customers convert at 3–5× the rate of new ones. If your 'impressive' blended ROAS is driven by existing customers, you are not growing — you are retaining. Separate these segments in reporting. If new customer ROAS is below break-even, you are losing money on every new customer regardless of how good the blended number looks.
Contribution margin per order
The metric that determines whether you can actually scale. Formula: revenue − COGS − shipping − returns − ad spend − platform fees. Track this per campaign, not just account-wide. Some campaigns look profitable on ROAS but lose money when all variable costs are counted.
Feed quality — the most underinvested performance lever.
Google Shopping and Meta Catalog ads are entirely feed-driven. Most brands set up their feed at launch and never touch it again — which means missing attributes, generic titles, and poor image quality slowly bleed impression share and CTR for the life of the account.
Title optimisation
High impactInclude brand, product type, key attribute (color, size, material) in the first 70 characters. Google matches Shopping ads to search queries using product titles. Generic titles = missed matches = lost impressions.
Image quality
High impactWhite background for main image. Lifestyle images in supplemental feeds. Mobile-first rendering — product must be identifiable at 100×100px. Low-quality images reduce CTR 20–40%.
Custom labels
Medium impactTag products by margin tier, bestseller status, and seasonality. Use custom labels to separate high-margin products into separate campaigns with higher bids.
Missing attributes
Medium impactGTIN, brand, category, size, color. Missing attributes reduce eligibility for Shopping slots. Run a feed diagnostic monthly in Merchant Center.
Seasonal planning — Q4
Start Q4 planning in August. Build warm audiences through October Meta and YouTube campaigns. Reserve 20–30% of October/November budget for BFCM week. Produce BFCM-specific creative — generic creatives in a sale environment see 30–50% lower CTR. Plan landing pages for BFCM deals before October.

FAQ
Common questions about eCommerce paid media.
What is a good ROAS for eCommerce?+
A blended ROAS of 4–6x is healthy for most established eCommerce brands, but the number is meaningless without knowing your margin. A brand with 30% gross margin needs a 3.3x ROAS just to break even on ad spend before other costs. Calculate your break-even ROAS first: 1 / gross margin. Then set your target above that. Chasing a high ROAS number without knowing your margin is a common way to run at a loss while feeling profitable.
Should I separate new customer and returning customer campaigns?+
Yes, if you have the volume to support it. Returning customers convert at 3–5× the rate of new customers, which inflates your blended ROAS artificially. If you are primarily converting existing customers via paid retargeting, your CAC for new customers is likely much higher than your blended numbers suggest. Separating new vs returning gives you an honest new customer CAC — which is the number that determines whether your business is actually growing.
How should I plan paid media budget for Q4 / Black Friday?+
Start Q4 planning in August. Decisions to make: budget reserve (hold 20–30% of monthly budget in reserve for BFCM week), creative production (BFCM creatives need to be ready 3 weeks before), bid adjustments (CPCs spike 40–80% in BFCM week — plan for higher CPAs). Run awareness campaigns in October to build warm audiences before BFCM retargeting season. The brands that win BFCM prepared their audience pools in September.
Why does feed quality matter so much for Google Shopping?+
Google Shopping and Meta Catalog performance is entirely dependent on feed quality. Missing attributes (size, color, material), generic titles, low-quality images, and incorrect categorization all reduce your product eligibility and impression share. Optimised feed titles that match search queries can increase Shopping CTR by 30–60%. It is the most underinvested lever in eCommerce paid media — most brands set it up once and never touch it again.
What is contribution margin and why does it matter more than ROAS?+
Contribution margin = revenue − COGS − shipping − returns − ad spend − platform fees. ROAS only measures revenue / ad spend and ignores every other cost. A campaign with 8x ROAS can run at a loss if COGS is 60%, returns are 15%, and shipping is $8/order. Contribution margin per order tells you the actual profit generated after all variable costs. Track this number, not ROAS, when evaluating whether to scale.
