Warning::

Page URL https://51job.com 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.

Match: Very different

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.

Learn more ▾

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.
