常見問題
03
Does this fetch a live page?
No. It checks the URLs you enter and generates the tag snippet locally.
What is a self-canonical?
A self-canonical is when a page declares itself as its own canonical, signaling that it is the preferred version of that URL.
When would a cross-domain canonical be used?
When content appears on multiple domains and you want search engines to consolidate authority on one preferred version.
