Google Shopping agency as an external ecommerce performance partner
For many industries: Google Shopping Ads that fit assortment and margin
No matter the industry: the pitfalls in Google Shopping are similar. The Shopping Feed is incomplete, products get rejected, categories are incorrect, or Merchant Center and campaign logic do not integrate cleanly – and potential is lost as a result.
This is exactly where Nakaryu comes in: You get a well-coordinated shopping team consisting of Feed Strategy, Data Quality, Product Texts, Campaign Management, Remarketing, Reporting, Testing and Merchant Center Setup – with clear processes, rapid iterations, and a focus on Performance. Instead of „somehow running“ campaigns, we build a reliable system: clean feed structure, title & attribute optimization, exclusions, product group logic, and evaluations that show which levers really work.
The special thing: We don’t think of Google Shopping as „a few product ads“, but as a repeatable revenue channel – with feed hygiene, testing, and clear learning logic. We translate your goals into a suitable campaign architecture, prioritize products by margin/availability, and optimize based on data. Whether a small shop or a large assortment – Nakaryu adapts setup and pace to your structure.
Plannable, fast and transparent: as monthly support with clear deliverables, fixed processes, and a team that continuously optimizes. So that spend turns into measurable shop results – and clicks into real purchases – sustainably, scalable, and without chaos in the Merchant Center.

We manage Merchant Center & Google Shopping for many industries
When do I need which package?
Google Shopping Start with Clean Product Data
Farbwerk Süd GmbH
„The painting company launched a small webshop with 45 specialty paints and tools but failed due to constant rejections in the Merchant Center because of missing GTINs. With the Starter Package, we technically set up the feed cleanly, standardized all product attributes, and placed the products error-free on Google – the perfect, straightforward entry for a clear, manageable assortment.“
Expand Assortment & Stabilize ROAS via Shopping
Tanzraum Leipzig
„Tanzraum Leipzig has evolved from a local dance school into a small online shop for dance shoes, training clothing, and accessories. The assortment grows every month, but not all categories perform equally well. Now, bestsellers should be scaled more strongly, weak products limited, and the feed regularly further developed. For this, the shop needs more testing and continuous optimization.“
Google Shopping Agency with Feed Pipeline & Testing
NadelKunst Berlin
„NadelKunst Berlin sells high-quality piercing jewelry in dozens of variants made of titanium, gold, and surgical steel. Manual feed maintenance was no longer sustainable with over 5,000 SKUs. With the Hero Package, we built an automated feed pipeline including regular A/B testing for ad texts and images – as a true Google Shopping agency that ensures scaling and data quality simultaneously across all channels.“
Multi-Assortment Google Shopping Management
Klangwerkstatt Süd
„With over 12,000 items, multiple brands, and complex inventories, the retailer needed comprehensive multi-assortment management. The Legend Package takes over complete handling: subfeeds for special promotions, automatic exclusion of unavailable items, cross-channel PMax testing, and continuous profitability control across all product groups – the all-round care for demanding large assortments with high transaction volume.“

Questions about the Google Shopping Agency? We have answers
FAQ
What is the difference between Google Merchant Center and Google Shopping?
The Merchant Center is the platform through which product data (feed) is submitted to Google. Google Shopping is the advertising format that displays this data in search results and in the Shopping tab. Without a clean Merchant Center, no Shopping campaign works.
How does Nakaryu work?
Nakaryu handles Merchant Center management and Google Shopping as a predictable subscription: You choose your hourly package, we flexibly take care of feed, setup, optimization, and reporting – transparently, scalable, and efficiently.
Who is Nakaryu suitable for?
For shops, brands, and teams who want to run Google Shopping Ads measurably without permanently building internal capacity for Shopping Feed, Merchant Center, and ongoing optimization.
What happens if Google rejects products or warns the account?
Product disapprovals usually arise from missing required attributes (e.g., GTIN, brand), price/availability discrepancies, or policy violations. We analyze the error diagnosis in the Merchant Center, clean the data directly in the feed or shop, and request re-approval from Google after correction.
How quickly can I get started?
Usually within a few days after orderconfirmation and a brief kick-off – so that Merchant Center, feed, and campaigns run smoothly and initial learnings emerge quickly.
What costs will I incur?
You only pay your booked monthly price. No hidden fees. External costs (e.g. tools, licenses, or advertising budgets) are transparently agreed with you in advance.
Additional Costs
We procure tools or licenses in consultation and pass them on 1:1. Advertising budgets for Google Shopping run transparently through your own ad accounts.
How are additional or overtime hours billed?
If the quota is used up, you can book additional hours – at a fixed rate of 95 € /h.
Is there a minimum term and notice period?
No, the package can be canceled monthly at any time.
What services are included?
Merchant Center setup, shopping feed optimization, product group logic, exclusions, budget control, reporting, and iteration – a shopping team without coordination chaos.
Which shop systems are supported (e.g., WooCommerce, Shopify)?
We primarily support WooCommerce- and WordPress-based online shops but also assist common e-commerce systems. A clean interface (feed export via XML/CSV or API) is crucial to ensure product data is transmitted automatically and error-free.
How quickly are tasks implemented?
Usually within a few days. Depending on priority, we coordinate timings with you; urgent matters (e.g., sale start, launch, seasonal peak) can be implemented at short notice by arrangement.
Are websites or shops included?
Web design is not part of shopping support but can be booked as an add-on. Since websites incur ongoing costs (hosting, maintenance, licenses), we offer a separate web design flat rate for this. You can even book this directly as an add-on at the top of the configurator.
Which feed attributes are indispensable in 2026?
At least 8 attributes per product: title (keyword-optimized), GTIN (mandatory for branded products), product type, brand, category, price, availability, image. Custom labels for margin, bestsellers, or seasonality enable KPI-driven campaigns.
How flexible is the collaboration?
You book monthly plannable hour packages. Unused hours can be carried over for one month. The subscription can be canceled monthly at any time.
How does communication work?
You have a dedicated contact person and can reach us by email, chat, phone, or video call. We work like your internal shopping team – fast, efficient, and clearly structured. We are also happy to visit you on-site at your expense.
How is support handled during the collaboration?
Regular coordination, simple approval processes, and clear reporting ensure that Merchant Center management runs smoothly and you always keep an overview.
Can I add or change services at any time?
Yes. Within your hourly quota, we prioritize tasks flexibly. If you need more, you can book additional hours or switch to a larger package.
How are hours documented?
We record all hours in an online tool. Upon request, you will receive monthly summaries so you can see exactly how your quota was used.
This fits the Google Shopping management subscription
