Can a canonical tag point to a completely different domain?

Yes, cross-domain canonicals allow syndicated content to attribute ranking power back to original author sources.

Should every single page have a canonical tag?

Yes! Every indexable page should have a self-referencing canonical tag to protect against accidental duplicate scrapers.

Can I use relative paths in canonical tags?

No! Always use absolute URLs (https://example.com/page) to prevent crawling ambiguities.
