Cross-Channel Optimization of Marketplace and External Ads to Maximize ROAS
"ROAS keeps improving, but profits aren't growing" -- this is one of the most common concerns we hear. An ad agency's job is to optimize ad performance. That is valuable work. But maximizing profitability across the entire EC business is not always the same thing. Product cost ratios, marketplace fees, logistics costs, repeat purchase rates -- to judge whether ad spend on a given product is worthwhile, you need to understand the EC business itself. Meets Consulting directly operates EC stores through our group company, investing our own ad budget to generate revenue and profit. Because we experience advertising as a "cost," we can design ad strategies reverse-engineered from operating profit, not just ROAS.
Spending on ads every month, but no profit remains
Your ad agency's reports don't align with actual sales figures
Unsure how to allocate budget across Amazon ads, Rakuten RPP, Google ads, etc.
ROAS looks fine, yet profit margins are declining
Marketplace ads and external ads (Google/Meta) managed by different teams with no coordination
Need strategic recommendations beyond "increase your ad budget"
Unable to determine whether to boost ads during sales events or invest steadily year-round
Cannot track whether ad-acquired customers are making repeat purchases
If any of these resonate, let's talk.
Get Free ConsultationEC advertising effectiveness cannot be measured by ad dashboard metrics alone. "Did this ad drive actual purchases?" "Are ad-acquired customers making repeat purchases?" "Did boosting ads during sales events increase or decrease profit?" -- the real impact on revenue and profit is only visible when you operate EC yourself.
Meets Consulting directly operates EC stores through our group company, running continuous PDCA with our own ad budget. Marketplace algorithm changes affecting ad performance, seasonal CPC fluctuations, varying ad responses across product categories -- instead of experimenting with client budgets, we validate strategies with our own budget first, then apply proven approaches to your advertising.
ROAS is the most common KPI in advertising. It is an important measure of ad efficiency, but improving ROAS does not automatically improve profit. Applying a uniform ROAS target to high-cost products can result in losses even with good ROAS. Increasing ad spend may grow revenue while consuming all gross margin.
Meets Consulting factors in product-level cost ratios, marketplace fees, and logistics costs to determine "which products to push with ads" and "which products to grow through organic search". Ad budgets are designed within the overall EC business P&L. Aligning advertising KPIs with business KPIs is the foundation of our approach.
Amazon Sponsored Products, Rakuten RPP and TDA, Yahoo! Item Match -- marketplace ads. Google Ads, Meta Ads (Instagram/Facebook), LINE Ads -- off-platform ads. In many companies, marketplace ads are managed by the EC team while external ads are handled by an ad agency -- separate people, separate organizations.
This fragmentation is the problem. Which channel acquires new customers more efficiently? Which brings in higher-LTV customers? Without cross-channel comparison, optimal budget allocation is impossible. Meets Consulting manages all ad channels -- marketplace and off-platform -- through a single team, delivering true cross-channel optimization.
Advertising is a "traffic" tool. But traffic alone does not grow revenue. If product page conversion rates (CVR) are low, ad spend is wasted. If ad-acquired customers do not return, LTV does not improve.
Meets Consulting positions advertising as part of the overall EC growth strategy. Alongside ads, we improve product pages, marketplace SEO, and LINE CRM for repeat customer development -- holistic optimization from acquisition to conversion to retention, all designed and executed by a single team. Optimizing ads in isolation cannot maximize business-wide profitability.
We design and manage end-to-end digital advertising strategies to maximize EC business revenue and profitability.
A dedicated team with deep expertise in each marketplace's ad products designs and manages bidding strategies based on product-level profit margins.
We manage Google Search Ads and Yahoo! Search Ads to drive off-marketplace traffic. From sending visitors to your own EC site to directing traffic to marketplace product pages, we design campaigns for brand keyword defense and new customer acquisition through generic keywords.
Instagram, Facebook, LINE, TikTok -- unlike search ads, social ads can reach potential customers who are not yet ready to buy. For EC businesses, we design a two-pronged approach: expanding new awareness and retargeting for conversion.
Display and video ads are effective for brand awareness and retargeting site visitors. For EC businesses, video creatives that showcase product use cases and brand storytelling are particularly impactful.
Ad performance depends not only on targeting and bidding but heavily on creative quality. Because our ad operations and creative teams are in the same organization, we run rapid A/B testing driven by performance data to continuously improve creative effectiveness.
"ROAS in the ad dashboard looks good, but actual profits are not growing" -- to close this gap, Meets Consulting performs integrated analysis combining ad data with EC business data.
We audit your current ad accounts, cross-referencing ad dashboard data with overall EC business revenue and profit data to assess "whether ad spend is actually contributing to profitability." If you currently work with an ad agency, we also evaluate the quality of their management.
Based on audit findings, we design an advertising strategy factoring in product-level margins, sales channels, and competitive landscape. This includes marketplace vs. off-platform ad allocation, product-level investment priorities, and a monthly budget plan reverse-engineered from your P&L.
We restructure ad accounts and begin operations. The first 1-2 months focus on data collection and hypothesis testing -- intensive A/B testing of bidding strategies, targeting, and creatives to establish optimal patterns for your products and market.
Building on patterns established during initial optimization, we progressively scale ad budgets and introduce new initiatives. Weekly performance reviews and monthly strategy meetings ensure sustained profit growth.
New product launches, new channel expansion, seasonal adjustments -- as your EC business evolves, your advertising strategy evolves too. We also recommend product page improvements and CRM integration as needed.
Digital advertising management pricing is tailored to your specific situation and needs. We start with a free consultation to understand your current state and provide a customized proposal.

The role and KPI setting differ. Ad agencies specialize in optimizing ad performance, which is critical expertise. Meets Consulting focuses on maximizing profitability across the entire EC business. We go beyond ad management to recommend "this product should be sold through SEO, not ads" or "reallocating ad spend will improve margins" -- strategic proposals grounded in the EC business context. We can also work alongside your existing agency with a "Meets handles strategy, agency handles execution" model.
We do not set a strict minimum, but our support delivers the greatest impact with monthly ad budgets of 300,000 yen or more. For smaller budgets, we may recommend first building an organic revenue base through marketplace SEO and product page optimization.

Yes. From banner design and video ad production to landing page creation, our advertising operations and creative teams work together. We conduct continuous A/B testing driven by performance data to keep improving creative quality.
That is precisely our strength. Advertising is just one traffic tool. Product page CVR improvement, marketplace SEO, LINE CRM for repeat customer development -- we design and execute holistic optimization from acquisition to retention, all through a single team. This delivers greater business-wide profit improvement than optimizing ads alone.
We send weekly flash reports on key KPIs and monthly detailed analysis reports. Monthly reports include not only ad performance but also contribution analysis to overall EC business revenue and profit, next-month action plans, and ad budget adjustment recommendations. We also hold monthly strategy meetings (online).
We will audit your current ad accounts at no charge. By cross-referencing ad dashboard data with your EC business revenue and profit data, we make visible "how much of your ad spend is actually contributing to profit."
