WWW Canonical Checker
Verify if www and non-www versions converge to one canonical URL.
Example inputs: webboar.com, github.com, wikipedia.org
Why canonical host consistency matters
When both www and non-www versions of a site remain accessible without clear convergence, search engines may split crawl attention and ranking signals across duplicate hosts. Teams often notice this as inconsistent indexation, fluctuating canonical picks, or analytics fragmentation where sessions appear on multiple hostnames. This checker compares both entry points and shows whether they land on one final canonical target.
Use this during migrations, CDN reconfiguration, SSL renewals, and any routing change touching edge rules. A practical pattern is to test homepage + 3–5 top landing pages after each deploy. If either host resolves differently or requires multiple hops, fix edge redirect logic first (single permanent redirect to preferred host), then validate canonical tags with Meta Tag Inspector. Keep the same host policy in sitemaps, internal links, and hreflang to avoid mixed signals.
For operators, the biggest win is consistency, not complexity. Pick one host standard, enforce it everywhere, and re-check regularly. This reduces crawl waste, improves cache predictability, and keeps measurement cleaner across SEO, paid landing pages, and conversion reporting.
Practical FAQ
Should I choose www or non-www?
Either can work. The important part is strict consistency: one canonical host, one redirect policy, and matching canonical tags/sitemaps/internal links.
Is one redirect hop acceptable?
Yes. One permanent hop is normal. More than one hop adds latency and can create crawler inefficiency, especially across large URL sets.
Why can this pass on homepage but fail on deeper pages?
Because route-level rewrite rules may differ from root behavior. Always test representative page types, not just the homepage.
