Creator Guidelines & Practical Tips
When posting on X / Twitter, keeping captions and subtitles within visible safe zones prevents your message from being covered by mobile app icons (like buttons, comment trays, usernames, or audio tags). For text posts, proper line spacing ensures your paragraphs remain clean and readable across both iOS and Android apps.

💡 Frequently Asked Questions
Q: Who can publish Articles on X / Twitter?
Long-form publishing features are available to subscribers of X Premium+ as well as verified organizations.
Q: How do I structure an X Premium Long-Form Article headline so the thumbnail summary card doesn’t truncate on mobile?
Target ~55–70 characters for the headline and put the core keyword + outcome before any brand name. Use simple punctuation (no fancy dashes) and avoid emojis in the first line, since they often trigger earlier truncation.
Q: What’s the best way to A/B test headline + card preview so I can pick the winning version quickly?
Run two variants that differ by only one element: either the headline wording OR the first summary sentence. Post both within 24–48 hours, then compare CTR to the long-form article link (not likes) and pick the version with higher clicks per impression.
Q: What headline length gives an X Premium Article the best timeline card preview?
Aim for 55–70 characters and put the core subject in the first 40 characters, because longer headlines can truncate on narrow mobile cards. Preview at 320 px and 390 px widths, then shorten any headline that hides the promise or key entity.
Q: Why does my X Article thumbnail look blurry or lose its focal point in the card preview?
Use a 1200×628 px or larger source image, export at 80–90% JPG quality, and keep faces, logos, and product details within the central 80% safe area. Avoid screenshots with tiny text; timeline cards are often rendered near 320 px wide, where fine detail disappears.
