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.

11 characters Too short
Title: Information
H1: BMC, Research in progress
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.
