Google Search Console

최종 업데이트:

Definition

Google Search Console (GSC) is a free tool from Google for monitoring site search performance, diagnosing indexing issues, and submitting sitemaps. It is the only official source for Google search data.

Summary

GSC is the foundation of SEO measurement. Performance reports show clicks, impressions, CTR, and average position. Indexing reports diagnose crawl and index problems. URL Inspection checks individual page status. Register every site and review weekly.

Why GSC is essential

Only official Google search data source

Third-party tools (Ahrefs, Semrush, etc.) estimate rankings and traffic. GSC provides actual Google search data — clicks, impressions, queries, and pages that actually appeared in results.

Free and comprehensive

No cost. Covers performance, indexing, sitemaps, manual actions, Core Web Vitals, and more.

Required for indexing requests

After fixing indexing issues, GSC URL Inspection is the only way to request re-indexing.

GSC registration and setup

Step 1: Add property

  1. Visit search.google.com/search-console
  2. Add property — choose domain or URL prefix
  3. Verify ownership (DNS, HTML file, HTML tag, Google Analytics, etc.)

Recommendation: Domain property (example.com) covers all subdomains and protocols.

Step 2: Submit sitemap

GSC → Sitemaps → enter sitemap URL (e.g., https://example.com/sitemap.xml)

Step 3: Connect Google Analytics (optional)

Linking GA4 and GSC enables combined analysis in GA4 Search Console reports.

GSC data limitations

2–3 day delay

Performance data is not real-time. Expect 2–3 days before new content or changes appear.

Query data sampling

GSC may sample query data on high-traffic sites. Very low-volume queries may not appear.

16-month data retention

Performance data is kept for 16 months. Export regularly for long-term analysis.

No competitor data

GSC shows only your site's data. Use Ahrefs, Semrush, etc. for competitor analysis.

Weekly GSC checklist

  1. Performance: Clicks and impressions trend — up or down?
  2. Indexing: New "Not indexed" pages or reason changes?
  3. Manual actions: Any new penalties?
  4. Core Web Vitals: Pages failing LCP, FID, CLS?
  5. Top queries/pages: New opportunities or drops?

Local market application

GSC for local-language sites

GSC works for any language. Filter by country to see local market performance. Use hreflang for multi-language sites.

Naver vs GSC

Naver Search Advisor is the Naver equivalent but with fewer features. Google-focused SEO uses GSC as primary; Naver requires separate setup. See Naver Search Advisor Registration Guide for details.

Frequently asked questions

Q. Do I need GSC if I use Ahrefs or Semrush?
A. Yes. Third-party tools estimate data; GSC is the only official Google source. Use both — GSC for accuracy, third-party for competitor and keyword research.

Q. How often should I check GSC?
A. Weekly for most sites. Daily during core updates or after major changes. Set up email alerts for manual actions and security issues.

Q. Why don't my GSC clicks match Google Analytics?
A. GA counts all traffic sources; GSC counts only Google organic search clicks. Attribution, sampling, and date ranges also differ.

Q. Can I share GSC access with my team?
A. Yes. GSC → Settings → Users and permissions. Add users with Full, Restricted, or Owner access.

Q. What if I see "Discovered — currently not indexed"?
A. Google found the URL but hasn't crawled it yet. Strengthen internal links, add to sitemap, and request indexing. See Indexing Coverage Diagnosis for full process.
