import { defineConfig } from 'astro/config';
import { aeoAstroIntegration } from 'aeo.js/astro';

export default defineConfig({

    aeoAstroIntegration({

import { useEffect } from 'react';

export function AeoWidgetLoader() {
  useEffect(() => {
    import('aeo.js/widget').then(({ AeoWidget }) => {

          url: 'https://mysite.com',

        },
      });
    });
  }, []);
  return null;
}

React and Vue wrapper components are also available:

import { AeoReactWidget } from 'aeo.js/react';

<AeoReactWidget config={{ title: 'My Site', url: 'https://mysite.com' }} />

<script setup>
import { AeoVueWidget } from 'aeo.js/vue';
</script>

<template>
  <AeoVueWidget :config="{ title: 'My Site', url: 'https://mysite.com' }" />
</template>

Why AEO?

• 58% of searches end without a click — AI gives the answer directly
• 40% of Gen Z prefer AI assistants over traditional search engines
• 97% of sites have no llms.txt or structured data for AI crawlers
• 1 minute to set up with aeo.js

If your site isn't optimized for AI engines, you're invisible to a growing share of users who never open a search results page.
