# X profile optimization and AI footprinting

> This file defines how to structure an X profile so it is easy to understand by people, searchable on-platform, and useful as a conversion point for profile visitors.

---

## 1. Overview

An X profile acts as a compact public identity surface. X documents editable profile fields, a 160-character bio limit, pinned posts, and account-search preference for complete name, username, and bio fields.

The primary audience for this file is an agent tasked with rewriting a user's X profile. The outcome is a profile that clearly communicates authority, uses relevant keywords naturally, and provides a structured funnel for profile visitors.

## 2. Rules

### 2.1 The display name and handle

**Recommendation:** Include the primary keyword or job title in the display name when it improves immediate clarity and people-search discoverability.

**Recommendation:** Ensure the handle (`@username`) matches the user's brand across other platforms to build cross-platform entity trust for external search engines.

### 2.2 The Bio formula

The 160-character bio functions like a compact profile summary for people, search surfaces, and external previews. This is methodology layered on top of the official field limit, not a platform ranking guarantee.

**Recommendation:** Structure the bio using this formula: `[Who I help] + [How I help] + [Social Proof] + [Call To Action]`

**Recommendation:** Place the most critical niche terms early when doing so reads naturally.

### 2.3 The funnel (Pinned post and Highlights)

Historical ranking snapshots suggest profile clicks and downstream engagement can matter, and X search guidance favors complete profiles. The profile should therefore offer a useful next step without forcing weak proof.

**Recommendation:** Use a Pinned Post when the account has a strong evergreen asset. This acts as the top of the funnel (e.g., a lead magnet, a high-performing thread, or a newsletter link). If there is no strong evergreen asset yet, leave the pinned slot empty rather than pinning weak content. **Recommendation:** If the account has access to Highlights, curate testimonials, high-signal threads, and case studies to build authority for new visitors.

## 3. Examples

### Bio formatting

Good example:
```text
Helping SaaS founders scale organic traffic via programmatic SEO. Grew 3 startups to 1M+ monthly visits. Get my free technical SEO checklist:
```
*Why this is good:* It follows the formula precisely. Who/How: "Helping SaaS founders scale organic traffic via programmatic SEO". Proof: "Grew 3 startups...". CTA: "Get my free...". It reads naturally while hitting major keywords.

Bad example:
```text
SEO Expert | Growth Hacker | Digital Marketing | Coffee Addict | Views are my own
```
*Why it fails:* Keyword stuffing without context. It lacks a value proposition, social proof, and a CTA, providing no reason for a user to follow or understand the account's authority.

## 4. Anti-Patterns

### The misleading bio

**What it looks like:** A profile bio filled with provocative keywords outside the core professional niche, or a pattern of aggressive follow/unfollow behavior. **Why it fails:** Misleading positioning attracts the wrong audience and can lead to negative feedback events such as blocks, mutes, or reports. **What to do instead:** Ensure the bio accurately reflects the content to avoid misleading users who might otherwise mute or report the account.

### Link-tree only bios

**What it looks like:** A bio that only says "Links below" and points to a link hub. **Why it fails:** It wastes the limited bio space that search surfaces and profile visitors use to understand the account. **What to do instead:** Define the user's niche and expertise before adding the CTA for the link.
