Rule page.opengraph.image-missing

Add an og:image so shared links render a preview card

page.opengraph.image-missing is a check in Crawlmind's site audit that grades medium-impact issues of this kind. This page explains why the rule matters and the exact fix.

Impact: mediumEffort: low

Why it matters

When someone shares this page — in Slack, iMessage, LinkedIn, or an AI assistant that shows link previews — the platform looks for an `og:image` to build the card. Without one it falls back to a blank box or scrapes an arbitrary image. A deliberate preview image measurably lifts click-through on shared links, and shared links are a growing referral source as AI assistants surface citations.

The fix

Add these to the page `<head>` (absolute https URL, ~1200×630, under ~1MB):

```html
<meta property="og:image" content="https://example.com/share/your-page.png" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
<meta property="og:image:alt" content="Short description of the image" />
```

Use an absolute URL — relative paths are silently dropped by most scrapers. If every page shares one brand image that is fine, but a per-page image (e.g. an auto-generated card with the page title) performs better.
