Frequently Asked Questions
Q.Can I use both canonical and noindex on the same page?
No, this sends conflicting signals to Google. A canonical tag says "index the other version of this page," while a noindex tag says "drop this page entirely." Google may ignore the canonical if a noindex is present.
Q.Why did Google ignore my canonical tag?
Canonical tags are "hints," not directives. If the two pages are too different, or if internal linking heavily favors the non-canonical URL, Google may choose to index the non-canonical version instead.
