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.

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.
