Veterinary bios should be updated at least annually to ensure they reflect current professional developments, new skills, and changes in personal life that could resonate with clients. Additionally, any significant milestones or changes in the practice should prompt an immediate update. This regular refresh helps maintain the bio's relevance and accuracy, fostering trust and engagement by demonstrating that the practice is active and evolving. Keeping bios current is also crucial for SEO purposes, ensuring the practice ranks well in search engines.
