# Make articles eligible for Discover

For AI agents: the [site map](https://agentwranglers.se/llms.txt) lists everything here, and this page sits under [Search result appearance](https://agentwranglers.se/playbook/seo/search-result-appearance.md).

By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers.md). Updated 2026-10-22.

- ID: SEO-83
- Level: Optional
- Chapter: [Search result appearance](https://agentwranglers.se/playbook/seo/search-result-appearance.md)
- Rule: Give every article a large image at least 1200 pixels wide, allow it with `max-image-preview:large`, and name it in `og:image` or the article's structured data.
- Check: A build test reads every article. Its robots meta tag allows `max-image-preview:large`, and the image named in `og:image` is at least 1200 pixels wide and not the logo file.
- How: Google Discover shows articles in a feed people did not search for, and it favours large images. Google asks for images at least 1200 pixels wide, with more than 300,000 pixels in total, in 16 by 9 where you can. Without `max-image-preview:large`, Discover shows a small thumbnail. No special markup is needed beyond that. Use a picture of the story, not the site logo. Show the date and author as [Show the same date to people and machines](https://agentwranglers.se/playbook/seo/search-result-appearance/publication-dates.md) says.

## Examples

**Using these examples:** they show one way to follow this rule. Keep the behaviour and the check, not the syntax. Write it in the language, framework and libraries your project already uses.

### HTML example

```html
<meta name="robots" content="max-image-preview:large">
<meta property="og:image" content="https://example.com/images/oak-floor-before-after-1600.jpg">
```

### JavaScript example

```js
// Build test with sharp
const { width } = await sharp(imageFileFor(article.ogImage)).metadata();
assert(width >= 1200 && !article.ogImage.includes('logo'), article.path);
```

### Python example

```python
from PIL import Image
width, _ = Image.open(image_file_for(article.og_image)).size
assert width >= 1200 and "logo" not in article.og_image, article.path
```
