Frequently Asked Questions #
Should I write my bio in first or third person?
Write in third person for professional content. “Sarah Chen is an SEO Director...” reads more authoritatively than “I am an SEO Director...” Third person is the standard for byline bios and what AI systems expect to find.
How often should I update my author bio?
Update your bio at least annually, or whenever you have significant changes: new role, new certifications, major achievements, or updated expertise areas. Stale bios with outdated information can undermine credibility.
Can I use the same bio across all articles?
You can use a consistent base bio, but consider creating variations that emphasize different expertise areas depending on the article topic. For SEO content, emphasize SEO expertise; for content marketing pieces, highlight content strategy experience.
