# Open Graph Preview Tool: Common Mistakes and Best Practices

Most problems with open Graph Preview Tool aren't caused by not knowing what to do — they're caused by small, easy-to-miss mistakes that compound quietly over time. Here are the ones that come up most often.

Mistake 1: Leaving Open Graph tags entirely unset and letting each platform guess a preview, which often picks an irrelevant image or a truncated auto-generated description.

Mistake 2: Using an image with small text or fine detail that becomes unreadable at the tiny sizes most feed previews render it at.

Mistake 3: Changing a page's Open Graph tags and never re-scraping the URL, so old shared links keep displaying stale preview data indefinitely.

The fix for most of these isn't more effort, it's a regular check. A few habits that prevent them from creeping back in:
- Test previews on every major platform separately — Facebook, LinkedIn, and X/Twitter each cache and render Open Graph data slightly differently.
- Refresh cached previews after changing tags — most platforms cache the old preview aggressively and need a manual re-scrape via their own debugging tool.

Worth reading alongside this: our guide to SERP snippet preview, which covers the adjacent side of the same part of a technical SEO audit.
