What’s the safest way to use ChatGPT to schema markup to generate alt text that’s descriptive, not stuffed?

Question

Accepted Answer

The safest way to use ChatGPT for generating descriptive, non-stuffed alt text and schema markup involves a human-supervised, iterative process. Start by providing ChatGPT with clear, detailed prompts, including the image's context, purpose, and relevant keywords, alongside explicit instructions to prioritize description over keyword density. Crucially, instruct it to generate alt text that explains what is visible in the image and its function, always advising against keyword stuffing. Use ChatGPT as a drafting assistant, not an autonomous creator; its output should always be considered a starting point. Following generation, conduct rigorous human review and editing to ensure the alt text is concise, accurate, unique, and genuinely describes the image for accessibility and SEO. This multi-step validation process prevents inaccuracies, maintains brand voice, and ensures compliance with best practices for both users and search engines.
