Who this is for
- Global companies adding a Korean-language section or subdomain to an existing site
- Teams whose Korean pages rank inconsistently on Naver despite reasonable Google visibility
- Organizations relaunching or migrating a Korean site who need a pre- or post-launch technical check
Why a Korean-specific technical audit is different
A generic technical SEO audit checks crawl errors, sitemaps, and page speed the same way for any market. A Korean-specific audit adds checks a global template misses: whether Naver Search Advisor can verify and crawl the site at all, whether hreflang and canonical tags correctly separate Korean and non-Korean versions of the same page, and whether structured data is written in Korean rather than left in the source language where the visible content has been translated.
Mobile rendering is a second area global audits often skip. Korean text behaves differently from Latin text in the same layout: line height, word spacing, and font fallback can break on templates built and tested only in English, and a majority of Korean search traffic is mobile.
We also see sites where the Korean version exists but was never submitted to Naver Search Advisor, or where a sitemap update process built for Google Search Console never extended to Naver, leaving an entire platform blind to new or updated pages.
How SWIN runs the audit
We start with a full crawl of the Korean-facing pages using the same tools search engines use, checking response codes, redirect chains, robots.txt rules, and sitemap accuracy against what is actually live.
From there we review indexation status directly in Naver Search Advisor and Google Search Console (where access is available), hreflang and canonical implementation across Korean and non-Korean versions, and structured data validity for every schema type present on the site.
We finish with a mobile rendering pass specifically on Korean text and a prioritized list of fixes, ordered by how much each issue is likely limiting visibility versus how much engineering effort it takes to resolve.
What's included
- Full crawl and indexation review across Naver and Google
- Hreflang, canonical, and sitemap accuracy check
- Structured data validation for every schema type in use
- Mobile rendering review for Korean-language text
- Prioritized, engineering-ready fix list
How the engagement runs
Most audits run over one to two weeks: crawl and data collection first, then manual review of the areas automated tools cannot judge on their own, such as whether structured data actually matches the visible Korean content it describes. We deliver findings as a written report your development team can act on directly, and we're available to answer implementation questions as fixes go in, though we do not require you to hire us for the fix work itself.
Is this the right starting point for you?
If your Korean content strategy already exists but visibility is inconsistent or you are not sure Naver can even see your pages correctly, an audit is usually the right first step, before investing further in content. If you have no Korean-language content yet, Korean website design or Korean content localization is a more direct starting point, and a technical audit fits better once real pages exist to check.
Measuring the result
- Indexed-page ratio on Naver Search Advisor and Google Search Console
- Number of crawl errors and broken redirects resolved
- Structured data validation pass rate across page types
- Mobile rendering issues identified and fixed on Korean-language templates
Risks and constraints
An audit is diagnostic, not a guarantee of ranking improvement: fixing technical issues removes barriers to visibility, but content quality, competition, and publishing consistency still determine how far that visibility goes. Some findings require development resources beyond what a marketing team can implement alone, and we're upfront in the report about which fixes are quick wins versus larger engineering work.
Business value you can expect
Resolving indexing and structured data issues clears the technical ceiling on a Korean site's visibility, so the content and localization work you invest in afterward has a real chance to be found and understood by Naver, Google, and AI search tools.
