Who this is for
- Brands with an English product catalog preparing to sell directly to Korean consumers
- Companies listing on Korean marketplaces like Coupang, Naver Smart Store, or Gmarket for the first time
- Teams whose translated product pages have low conversion despite reasonable traffic
What changes on a Korean product page
Sizing and measurements need real conversion and, where relevant, Korean-market sizing standards, not a raw unit swap; clothing and footwear sizing in particular follows different conventions than US or EU sizing, and a mismatch here directly drives returns and complaints.
Korean shoppers also look for specific trust signals before purchasing: clear return and exchange policy details, delivery timeframes, a visible customer service contact method (often a Kakao channel rather than only email), and, for certain categories, certification or origin information displayed prominently rather than buried in a policy page.
Product imagery frequently includes in-image text (size charts, feature callouts, usage instructions) that needs to be localized as image text, not just the surrounding page copy, or Korean shoppers are left working from an English infographic embedded in an otherwise Korean page.
How SWIN approaches product page localization
We start with a review of your current product catalog and page template to identify what needs full rewriting versus targeted adaptation, since not every product page needs the same level of rework.
We localize core copy, specifications, and sizing with correct conversions and Korean-market conventions, then rebuild or overlay in-image text where product photography includes size charts or feature graphics.
Where you're launching on a Korean marketplace specifically, we adapt content to that platform's template and formatting constraints, which often differ meaningfully from what your own DTC site allows.
What's included
- Product copy and specification localization with correct sizing and units
- In-image text localization for size charts and feature graphics
- Trust-signal review: returns, delivery, and customer service presentation
- Marketplace-specific formatting for Coupang, Naver Smart Store, or Gmarket where applicable
Process
We typically start with a small pilot batch of product pages to confirm tone, sizing conventions, and template fit before scaling across a full catalog, since catching conversion issues in a pilot of ten pages is far cheaper than finding them after localizing a thousand-item catalog.
Deciding where to start
If your catalog is large, prioritizing your top-selling or highest-margin products for a first pass usually produces faster, more visible results than localizing the entire catalog evenly. We can help identify which products to prioritize based on your existing sales data if you share it.
Measuring results
- Conversion rate on localized product pages versus prior English or machine-translated versions
- Return and exchange rate tied to sizing or description mismatches
- Customer service inquiry volume related to product information gaps
Common mistakes we see
- Sizing shown only in the source market's units, with no Korean-standard equivalent
- Size charts and feature callouts left as untranslated text baked into product images
- Return and delivery policy details buried in a separate page instead of shown near the buy button
- No visible Korean-language customer service contact method on the product page itself
Risks and constraints
Sizing and specification accuracy depends on the source data you provide being correct and current; we localize and convert what you give us, and we're not positioned to catch manufacturing or specification errors in the original English listing. Marketplace-specific requirements (business registration, category approval) are the seller's responsibility to secure and fall outside this service.
Business value you can expect
Product pages that present sizing, policies, and trust signals the way Korean shoppers expect reduce the friction and hesitation that translated-but-unadapted pages create, without needing to overhaul your entire ecommerce platform.
