Canonical is a signal for the representative page in a set of duplicate or very similar URLs. Google considers the user's canonical but may choose a different URL based on other signals such as redirects, sitemaps, internal links, content similarity, and HTTPS.
Duplicate, Google chose different canonical than user
Duplicate without user-selected canonical
Alternate page with proper canonical tag
Canonical is a signal for the representative page in a set of duplicate or very similar URLs. Google considers the user's canonical but may choose a different URL based on other signals such as redirects, sitemaps, internal links, content similarity, and HTTPS.
Distinguish between crawling, indexing, canonical, performance or ranking issue.
Compare current HTTP, HTML, header and render output with Google's recorded data.
Verify that canonical, sitemap, internal linking, robots, and redirects point to the same URL intent.
Develop content taking into account that technical suitability is not a guarantee of index or ranking.
Do not consider canonical as a ranking trick or forced redirect.
Meaning: Google chose a different URL as the representative.
Possible cause: Canonical signals are conflicting.
Meaning: User preference is not available in the duplicated group.
Possible cause: Self canonical missing or different URL versions.
Meaning: Alternative URL with correct canonical linked to another page.
Possible cause: Expected repeat behavior.
Meaning: The canonical target is not the final 200 URL.
Possible cause: Old canonical or chain transfer.
Meaning: Representative URL is closed to indexing.
Possible cause: Noindex and canonical conflicts.
Meaning: Both protocols are accessible and signals are mixed.
Possible cause: Missing redirect or incorrect sitemap.
Meaning: Filter/UTM URL is using different content or wrong target.
Possible cause: General canonical template.
Meaning: Canonical is not an absolute command.
Possible cause: Google also evaluates other signals.

Compares protocol, host and slash versions.
curl -s https://example.com/sitemap.xml | grep -F 'https://example.com/page'
Shows whether the preferred URL is present in the sitemap.

Examines the host/URL formats used in special projects.
curl -sI https://example.com/page | grep -i 'x-robots-tag'; curl -sL https://example.com/page | grep -iE 'noindex|canonical' | head -n 20
It checks the index permission of the Canonical target.
SEO plugin output should be checked in attachment, feed, pagination, variation and filter URLs.
Canonical route should be generated based on query string and language parameters with a central helper.
TR/EN URLs should not be canonicalized together; hreflang should remain as an alternative.
After removing the technical barrier, the re-crawl and re-evaluation period by Google varies depending on the URL, site, and issue type; there is no certain time or index guarantee.
No. The request is only a re-crawl signal; if technical issues, canonical, content quality, and internal linking problems are not resolved, the result may not change.
No. It serves as a helper signal for sitemap discovery and canonical preference; it does not guarantee crawling and indexing.
The plugin facilitates meta and sitemap production, but does not solve content, server, internal link, canonical, and Search Console analysis on its own.
Google does not specify a technical character limit; the result view may be shortened depending on the device and query. The title should be short, descriptive, and unique.
Google has removed the rich results feature from the FAQ section as of May 7, 2026. The FAQ section can be kept for user benefit, but there is no guarantee of rich results.
No. The guide helps to systematically solve technical and content issues; ranking depends on competition, quality, authority, user demand, and Google systems.
