See Accessibility tab for detailed alt text quality analysis.

Search engines use filenames as a signal. Rename to descriptive names like 'team-photo.jpg'.

Why this matters

Most image filenames are non-descriptive (hash/IMG_X) — small SEO miss for Image Search ranking.

Sitemap Freshness
Action
Sitemap exists but no <lastmod> entries
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.

Title

"Treccani, il portale del sapere - Treccani"

42 characters Optimal ✓
Title: Treccani, il portale del sapere - Treccani
H1: EVOLUZIONE
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.

Very low ratio suggests heavy framework overhead or boilerplate.

Why this matters

Informational: ratio of visible text bytes to total HTML bytes. Very low ratios suggest excessive markup overhead.

PASS
1 markup-quality issue(s) detected
Info::
`<meta charset>` declared at byte 121115 -- past the 1024-byte spec window
The HTML5 spec requires the encoding declaration to appear in the first 1024 bytes. Browsers that started parsing in a default encoding and discover the real charset later DISCARD parsing state and re-parse from the top -- a measurable hit to First Contentful Paint. Move the `<meta charset>` tag to be the first child of `<head>`.
