Tagging images for SEO is crucial for both users and search engines, as it enriches page content and ensures accessibility standards compliance. Selecting highly relevant images, applying alt text attributes with descriptive text (3-15 words), and using image title tags can improve relevance and contextual understanding of pages. While manual tagging can be labor-intensive, automated solutions like AI-powered tools or DAMs can save time at scale. Prioritizing image optimization is essential, as neglecting to do so leaves opportunities on the table for improved traffic and accessibility compliance. By implementing SEO image tags, users and search engines alike benefit from a more inclusive web experience.
