Canonical tag
A hint that identifies the preferred version of near-duplicate pages so signals consolidate to the canonical URL.
The canonical tag suggests the primary URL when multiple pages have similar or duplicate content (e.g., tracking parameters, pagination). It matters because dispersion of signals can weaken rankings. Canonicals influence crawling and indexing by consolidating link equity and clarifying which version should appear in results. They should align with internal linking and sitemaps; mismatches confuse crawlers.
Key Takeaways:
- •Match canonicals to internal links and sitemaps
- •Use self‑canonicals on unique pages
Context:
A blog uses UTM parameters for campaigns.
Action:
Self‑canonicals point to clean URLs; sitemaps list canonical versions.
Result:
Consolidated signals reduce duplication; performance reporting remains accurate.
