Why it matters
A canonical link tells search engines which URL to show when the same page is reachable at several addresses.
How to fix it
Add a self-referencing canonical link to every indexable page, using the final https:// URL.
How we check
The homepage includes <link rel="canonical">.
Observed: Canonical link present.
Not observed: No canonical link.
Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
