TechySEO audits every canonical tag across your entire website β checking HTML head canonicals and HTTP header canonicals simultaneously β to detect missing tags, chains, conflicts, and misdirected authority before they cause indexation problems.
Canonical tags tell Google which version of a page is the authoritative one to index. When a canonical points to the wrong URL, link equity flows to the wrong page. When a canonical is missing entirely, Google must decide on its own which URL to treat as canonical β and it often chooses differently than you'd prefer.
Canonical chains β where Page A canonicalizes to Page B, which canonicalizes to Page C β are inefficient and unreliable. Google will usually resolve the chain eventually, but this is wasted crawl budget and creates fragile canonicalization that breaks when any link in the chain changes.
Pages that are both noindexed and have an outgoing canonical create a direct conflict that confuses crawlers about your true intent β TechySEO detects every one of these contradictions.
TechySEO checks every canonical signal source and every possible conflict type β HTML, HTTP headers, and directive interactions.
TechySEO audits every canonical tag on every page β detecting conflicts, chains, and missing tags before they split link equity or cause indexation problems.
