Multiple title tags

The page has no <title> tag. Search engines fall back to the URL or a fragment of body text, which hurts click-through.

Titles wider than what Google shows (~580px on desktop) are truncated in search results, hiding the part that converts. Truncation depends on the rendered width of the characters, not just their count.

Very short titles miss ranking-relevant keywords and look thin in SERP listings.

Two or more pages share the same title, making them compete in search results.
