X Profile Optimisation: Bio, Pinned Post, Header, Handle

Your profile is the conversion page for every post you have ever written. A post's job is to earn the tap; the profile's job is to turn that tap into a follow. Most accounts spend all their effort on the first half of that sentence, which is why so many of them have high impressions and flat follower growth.

The whole pass takes an afternoon, it is the only work on X that improves the return on every future post at once, and it is worth redoing whenever what you post about changes.

The handle

Short, memorable, typeable from hearing it out loud. Avoid numbers and underscores where you can — they are the shape people associate with throwaway accounts, and they make the handle hard to relay verbally. If your name is taken, adding a topic word usually reads better than adding digits.

Changing a handle later is possible and does not delete your history, but it does break every link anyone has ever shared to your profile and every mention that pointed at the old name. Worth getting right early; not worth agonising over at a thousand followers.

The display name

This is the string that appears beside every post you make, everywhere, including under other people's posts where most strangers will first see you. It has room for a name plus a short qualifier, and the qualifier is where the value is: a name alone tells a stranger nothing.

• Name plus what you do is the reliable pattern — a person and a category, separated by a divider.
• Keep it short enough to survive truncation on a narrow phone. Long names get cut off and the cut usually removes the useful half.
• Avoid decorative characters. Emoji and symbol clutter read as spam at a glance and can make the name harder to search for.

The bio

You have 160 characters and about one second of attention. The bio should answer what this account posts about and why a stranger should care, in that order. Almost every weak bio fails by describing a person instead of a feed.

1. Lead with the subject, not the job title. Readers are deciding whether to subscribe to a topic.
2. Add one piece of specific evidence if you have it — something concrete and checkable, not an adjective.
3. Say what to do next if there is a next step, in three or four words.
4. Cut every generic word. Passionate, enthusiast, guru and thought leader are pure filler and cost you the characters that could have carried information.

The photo and the header

The profile photo is displayed small and circular almost everywhere it appears, so it has to work at the size of a fingernail. A face cropped close beats a full-body shot, and a logo works for a company but reads as corporate for a person. Upload it square, around 400 pixels, and check it at thumbnail size before committing.

The header is roughly a three-to-one banner, around 1500 by 500, and it is the one place a profile has room to state something. It gets cropped differently across devices, so keep anything important away from the edges and out of the bottom-left where the avatar overlaps it. A header with a single clear line works; a busy collage does not.

The pinned post

This is the most under-used asset on the platform. Every visitor sees it, which makes it the only post you can guarantee an audience for — and most accounts have a months-old announcement sitting there doing nothing.

Pin your single best piece of work, or the one post that best explains what the account is for. If you have something to offer, the pinned post is also the best place to make that ask, because the reader arrived deliberately rather than while scrolling. Review it monthly; an out-of-date pin is worse than none.

The link and the rest of the fields

One link, one destination, matching whatever the pinned post promised. A link-in-bio page listing six options converts worse than a single page asking for one thing — readers who have to choose usually choose nothing, which is the same rule that governs converting followers into customers generally.

Fill in the location if it is relevant to what you post about, and switch to a professional account if you want the analytics — they are free and post-level impressions are the data every other decision on this site depends on. The join date and follower count are not editable; they are simply part of what a visitor weighs, which is why the profile has to do its job well enough to survive being new.

The bottom line

Handle you can say out loud, display name with a qualifier, a bio about the feed rather than about you, a photo that survives a thumbnail, a header with one clear line, your best work pinned, and a single link to a single destination. An afternoon of work that raises the yield on every post you make from then on.
