Treat old terminology as an audit clue
When a website, slide deck, or media kit still says Twitter, use it as a prompt to inspect the actual destination. The important question is whether the link reaches the intended account and whether the visible identity remains clear.
This page focuses on historical references and maintenance. For selecting a current handle, use the separate X usernames guide. Keeping the tasks distinct helps you avoid treating an old link audit as a reason to rename a perfectly usable account.
Build a link inventory
Collect references from your website, email signatures, partner biographies, presentation templates, and downloadable documents. Record the visible label and the underlying address separately; one may have changed while the other has not.
Prioritize material you control and material likely to be reused. A template can reproduce an old address repeatedly. For an external article or an old printed item, record what cannot be edited and decide whether a practical continuity measure is available.
Verify before replacing
Open each important link and inspect the destination. Do not perform a blind text replacement across every file without checking the result. A username may have changed independently of a service's branding.
For account-setting questions, consult X's official handle-change guidance. Use the process appropriate to your actual account, and distinguish an ordinary rename from a marketplace allocation.
Explain continuity to people
When a name really has changed, provide collaborators with the exact current handle and a working link. Explain whether the same person or project remains behind the account. A short, factual note helps more than a vague announcement.
Use the social rebrand checklist for a coordinated change. The aim of this audit is to make the existing identity dependable, not to erase every historical reference that happens to use an older label.
