Title: 12 chars

Title: 12 chars
Info::
Page title is set
Got: Lien externe
Warning::
Title is only 12 characters — consider expanding
Info::
Title and H1 have very different wording
Alignment helps users confirm they've reached the right page.
Title

"Lien externe"

12 characters Too short
Title: Lien externe
H1: Institut national de recherche en sciences et technologies du numérique
Match: Very different
Robots: Indexable (no restrictions)

Alignment helps users confirm they've reached the right page.

Why this matters

Title and H1 disagree significantly — Google may treat one as the canonical topic and the other as off-topic, weakening ranking.

Title is the SERP headline; H1 is the on-page headline. They should describe the same page. Large divergence (different topics, different keywords) signals confusion and Google may rewrite the title in SERP. Align both to the same primary topic.
