Hreflang Has No Return Tag and Google Ignores the Cluster
Search Console reports "No return tags" on your hreflang cluster. Page A points to page B, but B doesn't point back to A. Google ignores the whole annotation.
🔍 SEO Crawling & Indexing Issues
URL unknown, Crawled / Discovered not indexed, sitemap submitted but not indexed, orphan pages, category / tag pages, new-site delays.
Google indexing is complex, but 80% of cases land on a handful of Search Console states: URL is unknown, Crawled — currently not indexed, Discovered — currently not indexed, Duplicate. One article per state — what the field means, when waiting is normal vs. when your structure is broken, and the shortest path to fix. We also separate the three most-misunderstood truths: submitting a sitemap does not guarantee indexing, URL Inspection does not force indexing, and slow indexing is not always a technical error.
Common problems
- New website not showing on Google Ten most-common causes in priority order.
- What "URL is unknown to Google" means What this Search Console state really means + next step.
- Crawled — currently not indexed Quality, internal links, domain sandbox — usual reasons.
- Discovered — currently not indexed Crawl budget and site authority.
- Sitemap submitted but pages not indexed Sitemap = discovery, not indexing.
- Page indexed but has no impressions Indexed ≠ ranking — intent and depth matter.
- Pages dropped from Google index Redesign / duplication / quality drop — three causes.
- Google crawls homepage but not article pages Internal link structure and homepage outbound links.
- Internal links not discovered JS rendering / nofollow / missing anchor text.
- Orphan pages — no internal links, no indexing Listed in sitemap but never crawled.
- Large content site indexing slowly Crawl budget vs. perceived site value.
- New category pages not indexed Category pages need real content, not just lists.
- Tag pages indexed but article pages lag Crawl order and internal link weight distribution.
- Why resubmitting URL does not solve indexing URL Inspection is a request, not a command.
- When indexing delay is normal New site / new section / post-redesign — 2-8 weeks normal.
- Pages in sitemap but missing from Search Console Sitemap parse failure / non-canonical URLs.
- Infinite scroll pages don't get indexed Paginated fallback URLs; SSR critical content; list in sitemap.
