Why Google Is Not Indexing My Site: Practical Fixes That Work
You publish new pages, request indexing, and still see nothing in Google. This is common on JavaScript-heavy sites: your page can be crawled but still fail index quality checks.
Crawl vs index: same visit, different decision
Crawl means Googlebot can fetch a URL. Index means Google decided the rendered content is valuable, unique, and stable enough to store.
Many teams celebrate crawl logs and miss the real bottleneck: rendered output quality. If Google receives thin HTML, duplicate signals, or unstable content, the URL stays discovered but not indexed.
- Crawl success does not guarantee indexation.
- Indexation depends on rendered content quality and canonical clarity.
- Soft-404, duplicate, and thin-content signals suppress indexing.
Hvorfor det betyder noget
Technical quality protects every SEO and conversion initiative. If rendering, caching, and crawl directives are inconsistent, content quality alone cannot unlock growth.
Implementerings-tjekliste
- Document route behavior before changing render or cache settings.
- Ship changes behind measurable checks (logs, alerts, and audits).
- Validate canonical, robots, and status-code behavior in staging.
- Create rollback steps for cache and routing changes.
Almindelige fejl at undgå
- Changing multiple infrastructure variables in the same release.
- Relying on lab metrics only and ignoring field data.
- Treating cache invalidation as a manual afterthought.
Top causes: JS content, empty HTML, crawl budget leakage
When your app relies on client-side rendering, Googlebot may fetch HTML that contains only a shell. If hydration fails or scripts are delayed, the meaningful content never reaches the index pipeline.
At scale, crawl budget gets consumed by parameter URLs, faceted duplicates, and low-value pages. Important URLs are crawled less often, then indexed slowly.

How Google renders and where failures happen
Google runs a two-wave process: fetch first, render later. Rendering is resource-constrained, so heavy JS can delay or break content extraction.
If your core content appears only after chained API calls, late hydration, or blocked scripts, indexing quality drops even when crawl status is 200.

Fix plan: prerender, SSR, dynamic rendering
Ship stable HTML for bots first. Pre-rendered output gives Google immediate content, while SSR keeps dynamic pages indexable without waiting for full client execution.
Dynamic rendering is a practical bridge if full SSR migration is not immediate. Route bot traffic to reliable HTML snapshots while your app stack evolves.
- Start with your highest-converting templates.
- Align canonical, robots, and sitemap freshness after render fixes.
- Monitor index coverage weekly, not only crawl counts.

Afsluttende pointe
If your page is crawled but not indexed, treat rendering output as the first diagnostic layer. Once Google sees complete HTML consistently, indexation usually improves within the next recrawl cycles.
Målinger at følge
- Crawl success rate
- Cache hit ratio by route
- LCP/INP field data
- Indexed vs submitted URL gap
