Automate Image Alt Text Auditing with AI
detail.loadingPreview
Streamline your website's accessibility and SEO by automatically auditing and generating alt text for your images. This workflow leverages AI to identify images with missing or insufficient alt text and provides suggestions for improvement.
About This Workflow
This n8n workflow automates the critical task of ensuring your website images have descriptive alternative text. It begins by extracting all images and their existing alt text from a specified page. The workflow then analyzes the length of the alt text and identifies images that fall short of best practices (under 100 characters in this configuration). For these images, it uses advanced AI (GPT-4o) to generate relevant and concise alt text suggestions. Finally, the entire audit and the AI-generated suggestions are neatly organized and saved into a Google Sheet for easy review and implementation, helping you boost both SEO and web accessibility.
Key Features
