Claude Skill: SEO and AIO-Optimized Alt Text Generator for Substack
By Karo
Category: Substack Mastery
How AI Overviews changed what image descriptions need to do. And a Claude skill that writes them for us.
Google used to treat alt text like a metadata field. A label for crawlers. We typed productivity-chart.png, maybe threw a keyword in, and moved on.
That is not how it works anymore.
AI Overviews and multimodal search engines like Gemini do not just read our alt text. They parse it as a semantic unit. They extract meaning, map entities, and decide whether our image deserves to show up as a standalone answer snippet.
Our alt text is not a label anymore. It is a micro-piece of content.
