eCommerce Google Ads Agency Singapore

Drive Business Growth With an eCommerce Google Ads Agency That’s Focused on Maximising your ROI

There are only 24 hours in a day, and within that span, every eCommerce brand is competing for that same pool of attention against marketplaces, against direct to consumer (D2C) competitors, and increasingly against rising costs per click. 

Winning that competition isn’t (as many believe) about spending more. It’s about running the right campaign types, feeding Google the right product data, and measuring performance against revenue, not clicks.

That’s a different discipline from general Google Ads management, and it’s what we do at Rogue Digital for eCommerce brands.

Key Takeaways

• eCommerce Google Ads success is built primarily on Shopping and Performance Max campaigns. 93% of retailers running Google Shopping ads now use Performance Max as their primary format.
• Shopping and Performance Max CPCs rose 15% year-over-year while average ROAS fell 43–46% over the same period, making efficient account management more valuable, not less.
• Retail and apparel categories convert at notably lower rates than the cross-industry Google Ads average, which means ecommerce accounts need to be benchmarked against ecommerce norms, not generic PPC standards.
• 97% of first-time website visitors leave without making a purchase. Remarketing is the mechanism that gives ecommerce brands a second chance at the large majority of visits that don’t convert immediately.

Why eCommerce Needs a Different Google Ads Approach

Generic PPC advice such as, improving Quality Score or testing ad copy still applies to eCommerce, but it misses what actually drives most eCommerce ad performance: product feed quality, Shopping and Performance Max structure, and remarketing built around the buying journey.

Because consumer journeys cut across multiple platforms, retailers are moving to Performance Max to automatically capture shoppers across the entire Google ecosystem (YouTube, Search, Maps, and Display) from a single campaign. 

In fact, 93% of retailers running Google Shopping ads have already moved to Performance Max as their primary format. Which means that campaign structure, and not just bidding, is central to how competitive an ecommerce account actually is. 

It doesn’t help that the margin for error is narrowing: recent data on ecommerce ad spend in some regions found Shopping and Performance Max CPCs rising 15% year-over-year, while average ROAS fell 43% on Standard Shopping and 46% on Performance Max over the same period. 

The rising costs and thinner margins mean the accounts that are actively, skilfully managed are pulling further ahead of the ones left on autopilot.

What Makes eCommerce PPC Different

Dimension	General / Service-Based PPC	eCommerce PPC
Primary ad format	Mostly text Search ads, often paired with Display or YouTube	Compared to traditional Search Ads, Shopping and Performance Max tend to work better for eCommerce brands, with dynamic remarketing playing a role in capturing potential customers who haven’t made a purchase
Core data input	Keywords and ad copy drive most targeting decisions	Keywords still matter for Search campaigns, but product feed (Merchant Center) data drives Shopping and PMax targeting
Primary KPI	Usually cost per lead or conversion rate	Usually ROAS and revenue per click, since the conversion event is a purchase
Conversion event	Typically a form submission, call, or booking	A purchase with an actual transaction value attached
Biggest lever	Ad relevance and landing page experience	Feed quality and structure, product-level bid decisions, and remarketing
Seasonality	Usually moderate	Events like Black Friday, 11.11, Christmas, or CNY can define a large share of annual revenue

Because the conversion event is a purchase with a real dollar value attached, eCommerce accounts can, and should, be optimised at a level of granularity most service businesses never touch: individual product performance, category-level ROAS targets, and margin-adjusted bidding.

The Rogue Digital Approach eCommerce Google Ads

Product Feed & Merchant Center Optimisation

Shopping and Performance Max campaigns are only as good as the product feed behind them. We optimise titles, descriptions, categorisation, and image quality in Google Merchant Center, the single highest-leverage lever in eCommerce PPC, since a poorly structured feed suppresses performance no matter how well the campaign itself is built.

Shopping & Performance Max Campaign Structure

Rather than dropping every product into one undifferentiated campaign, we structure Shopping and Performance Max campaigns by margin, product tier, and performance data. New products, “hero” bestsellers, and long-tail catalogue items each need different budget treatment and bidding logic to perform well.

Dynamic Remarketing

97% of first-time website visitors leave without making a purchase, a striking reminder that most first-time visitors to an ecommerce store are not lost causes, but simply need a second, well-timed nudge. We build dynamic remarketing campaigns that show visitors the exact products they viewed or abandoned in cart, layering in urgency or incentive where appropriate.

Dynamic remarketing campaigns show visitors the exact products they viewed or abandoned in cart.

Seasonal & Promotional Campaign Planning

Black Friday, 11.11, Christmas, and Chinese New Year can define an entire year’s ecommerce revenue in a matter of weeks. We plan budget scaling, promotional Shopping feed updates, and creative refreshes well ahead of these periods, rather than reacting once competitors have already claimed the auction.

ROAS-Focused Measurement & Bidding

We set Target ROAS based on your actual margin structure. A 3x ROAS on a high-margin product can be highly profitable, while the same 3x ROAS on a thin-margin category might not clear costs at all. Bidding strategy is calibrated to what’s actually profitable for your business, not a generic ROAS target copied from a benchmark report.

Why Work With Rogue Digital

A Full-Service Team Behind Every Campaign

Ecommerce performance depends on more than the ad account; product photography, landing pages, and content all affect conversion rate. As a full-service agency with in-house SEM, SEO, Content Writing, and Social Media advertising teams, we can support the whole conversion path, not just the ad spend.

Strategists Who Think in Margin, Not Just ROAS

A headline ROAS number means little without knowing your margin structure. Our strategists build bidding targets around what’s actually profitable for your specific catalogue as opposed to generic benchmarks pulled from an industry report.

Transparent, Revenue-Focused Reporting

We report on the metrics that matter to an ecommerce business, such as revenue, ROAS, cost per acquisition, and blended performance across campaigns, in plain language, with full access to your own ad account and Merchant Center.

Honest Recommendations

If your product feed needs work before your ad spend will perform, or if a particular category isn’t worth advertising given its margin, we’ll tell you directly. Our recommendations are built around what grows your revenue, not what grows your ad spend.

What Does eCommerce Google Ads Management Cost?

eCommerce accounts are typically priced with a management fee separate from ad spend, since ad spend scales directly with revenue goals and catalogue size. Singapore ecommerce brands generally invest SGD 500 to over SGD 10,000+ per month in ad spend, plus a management fee, with the right spend level depending heavily on catalogue size, category competitiveness, and how aggressively you’re looking to scale.

Feed quality drives cost-efficiency more than budget size. 

A well-optimised product feed can meaningfully lower CPCs and improve ROAS at the same spend level. It is often a higher-leverage investment than simply increasing the budget on a poorly structured account.

The PSG Grant applies to ecommerce PPC management too. 

Eligible Singapore SMEs can offset up to 50% of digital marketing management fees through the Productivity Solutions Grant when working with a pre-approved vendor.

Frequently Asked Questions

Do I need Shopping ads, Performance Max, or both? 

For most ecommerce brands, Performance Max, which now includes Shopping inventory, is the right starting point, since it lets Google’s automation allocate budget across Search, Shopping, Display, and YouTube based on where conversions are most likely. Standard Shopping campaigns still have a role where you want tighter manual control over specific high-value products.

How quickly will we see results? 

Shopping and Performance Max campaigns typically generate traffic within days, but meaningful optimisation usually takes 3 to 6 months as Google’s algorithms accumulate enough conversion data per product to bid effectively. New products in particular need a data-gathering period before judging their performance.

What ROAS should we be targeting? 

There’s no universal answer. It depends entirely on your margin. A useful starting point is calculating your break-even ROAS (based on gross margin) and setting targets above that, rather than adopting a generic “good ROAS” figure from an industry report that may not reflect your actual profitability.

Can you work with our existing Shopify, WooCommerce, or Lazada/Shopee presence? 

Yes. We work with your existing product feed and platform setup. The priority is usually improving feed quality and campaign structure rather than requiring a platform change.

Do you manage Meta and TikTok ads alongside Google Ads? 

Our core paid media expertise is built around Google Ads and SEM, and we can advise on how it should work alongside your other paid channels as part of a broader strategy.

Who owns our Google Ads and Merchant Center accounts? You do. We build and manage everything inside your own accounts, so all data, history, and learnings remain fully yours regardless of engagement length.
