Duplicate signal check

Why this exists
Useful first. Upgrade second.
Every free SEOGOD utility must give a business owner a useful answer without forcing them into a technical dashboard. The full product exists for the next step: monitoring, patching, proof, and ranking work across the selected project.
Can canonical tags force Google?
No. Canonical is a strong hint, not an absolute command. Consistent internal links and sitemaps help reinforce it.
Should canonical URLs include parameters?
Usually no, unless the parameterized URL is intentionally the canonical version.
What should match?
Canonical tags, internal links, sitemap URLs, redirects, and preferred URL format should all point in the same direction.
