> What the twitter:card tag does and why it still matters for consistent link previews.

Many platforms fall back to Open Graph, but the Twitter card tag is still a useful explicit signal.

A missing card type can reduce consistency in how the link is previewed.

## What It Is

The `twitter:card` meta tag tells X which preview format to use, such as `summary` or `summary_large_image`.

```html
<meta name="twitter:card" content="summary_large_image">
```

## Why It Matters

- It gives a direct preview-format instruction.
- It works well alongside your Open Graph tags.
- It helps keep social previews more predictable.

## Best Practices

1. Use `summary_large_image` when you have a quality preview image.
2. Keep related social metadata aligned.
3. Test one real share after deployment.

## Common Mistakes

- No twitter card tag.
- Using a large-image card without a real preview image.
- Letting card metadata drift away from actual page content.

## Quick Checklist

- twitter:card present.
- Card type matches available media.
- Social preview tested.

## Final Takeaway

Small tag, useful consistency. Add it when you care about clean shared-link presentation.
