Canonical URL

Minor issues

REVIEW

Minor issues

No canonical tag found

Search engines will determine the canonical URL themselves, which may cause duplicate content issues.

No Canonical URL Set

Page URL https://nextjs.org Canonical (not set)

Search engines will determine the canonical URL themselves, which may cause duplicate content issues.

Why this matters

Without a canonical, Google may treat each URL variant (with/without slash, with tracking params, http/https) as duplicate content and split ranking.

Learn more ▾

A canonical link tells Google which URL is the 'real' one when multiple URLs serve identical content. Without it, link equity gets split across variants and none of them rank as well as a single canonical version would. One <link rel="canonical"> tag in <head> covers it.

Search engines use filenames as a signal. Rename to descriptive names like 'team-photo.jpg'.

Why this matters

Most image filenames are non-descriptive (hash/IMG_X) — small SEO miss for Image Search ranking.
