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

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.

15 characters Too short
Title: badge-app-store
H1: The free, fun, and effective way to learn a language!
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.

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.
