A practical map of Google Search Console indexing statuses (Coverage): what each status means, the most common root causes (canonicals, duplicates, robots, redirects, soft 404s), and the fastest way to validate fixes.
A practical guide to the GSC status "Indexed, though blocked by robots.txt": why it happens, why blocking can freeze bad URLs in the index, and the safest resolution paths (allow crawl + noindex vs allow crawl + index).
A practical guide to the GSC status 'Not found (404)': how to classify URLs (keep/move/remove), when to 301 vs 410, and how to stop crawl waste.
A practical guide to the indexing status "Page with redirect": why it happens, when it's normal, and how to fix redirect chains so Google indexes the right URL.
A practical guide to redirect loops: common causes (www/apex, http/https, trailing slash), how to diagnose quickly, and how to fix without creating chains.
