Title

"ZDF Streaming-Portal: Filme, Serien und Dokus online anschauen"

62 characters Will truncate
Title: ZDF Streaming-Portal: Filme, Serien und Dokus online anschauen
H1: Zweites Deutsches Fernsehen
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.
