Title

"Lan Tian @ Blog"

15 characters Too short
Title: Lan Tian @ Blog
H1: AI Agent 试图扫描 DN42 时把主人搞破产了
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.

REVIEW
Sitemap exists but no <lastmod> entries
Info::
Sitemap has no <lastmod> entries
Without lastmod, Google can't tell which URLs have changed since the last crawl -- it falls back to crawling everything periodically. Adding lastmod (date or ISO 8601 timestamp) on each <url> entry signals freshness so the crawler prioritizes recently-modified pages.
