Warning::

Search engines will determine the canonical URL themselves, which may cause duplicate content issues.
No Canonical URL Set
Page URL https://www.data.gouv.fr 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.

Text-to-HTML Ratio

Very low ratio suggests heavy framework overhead or boilerplate.

Why this matters

Informational: ratio of visible text bytes to total HTML bytes. Very low ratios suggest excessive markup overhead.
