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.

Meta Tags

Title: 61 chars

PASS

Title: 61 chars

Page title is set

Got: Free K–12 Curriculum for Computer Science and AI | Code.org

Title is 61 characters — may be truncated in search results

Title and H1 have very different wording

Alignment helps users confirm they've reached the right page.

Title

"Free K–12 Curriculum for Computer Science and AI | Code.org"

61 characters Will truncate

Title: Free K–12 Curriculum for Computer Science and AI | Code.org

H1: AI is reshaping the world

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.
