Minor issues
Warning::
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://lwn.net 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.

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.

Title: 28 chars

Title: 28 chars
Info::
Page title is set
Got: Welcome to LWN.net [LWN.net]
Warning::
Title is only 28 characters — consider expanding
Info::
Title and H1 are identical
Consider differentiating — the title is for search results, the H1 is for the page.
Title

"Welcome to LWN.net [LWN.net]"

28 characters Too short
Title: Welcome to LWN.net [LWN.net]
H1: Welcome to LWN.net
Match: Similar ✓
Robots: Indexable (no restrictions)

Consider differentiating — the title is for search results, the H1 is for the page.

Why this matters

Title and H1 match exactly — internally consistent but misses an opportunity to optimize each for its audience (Title for SERP CTR, H1 for on-page).

Learn more ▾

Title and H1 don't have to be identical — and often shouldn't be. The Title competes for SERP click-through (lead with keyword + value prop), while the H1 confirms to the visitor they're on the right page (more conversational is fine). Differentiating gains both surfaces.
