How to Make SPAs Readable for AI Crawlers
Single-page applications built with React, Vue, or Angular are often invisible to AI crawlers. This guide explains why AI systems struggle with SPAs and how to fix it with SSR, static generation, or pre-rendering.
Why AI Crawlers Struggle with SPAs
Most AI crawlers, including GPTBot, ClaudeBot, and Google-Extended, do not execute JavaScript. When they visit a client-side-rendered SPA, they see an empty <div id="root"></div> with no actual content. Glippy's machine readability checker detects this issue.
