twitter:title
The title shown in X (Twitter) Card previews — falls back to og:title if not set.
twitter:title controls the headline in X/Twitter link preview cards. If this tag is absent, X falls back to og:title. Setting twitter:title explicitly allows you to use a title optimised for X's specific audience and card format — often more conversational or hook-driven than an SEO title.
For summary_large_image cards, the title is displayed below the image in bold. Twitter truncates titles at approximately 70 characters. The character limit encourages concise, punchy titles that work well in the timeline context.
Best practice: set twitter:title for important pages where you actively share content on X. For pages you rarely share, relying on og:title fallback is acceptable. Keep the value distinct from og:title only when the content is genuinely more engaging with a different angle.
