When the Open Graph Generator seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
Preview shows the wrong image
Point og:image at the absolute URL of the intended asset and clear the platform cache after fixing.
The description is ignored
Keep it concise and unique - platforms truncate or replace overly long text.
Preview still looks broken
Social platforms cache aggressively - use their debug or sharing inspection tools to refresh.
Tags are in place but nothing changes
Confirm they are inside the head and render server-side - client-only injection is often not seen.
Image dimensions are wrong
Use the recommended landscape ratio so the card does not crop awkwardly.
og:url does not match the shared link
Set it to the canonical URL of the page - mismatches confuse caching and analytics.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Using images below platform minimums
- Forgetting og:url canonical mismatch
- Reusing one image for every page
- Skipping tags and hoping for scraping
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
Which platforms read Open Graph tags?
Facebook, LinkedIn, Slack and most major social and messaging platforms.
Do I still need Twitter card tags?
Twitter/X prefers its own card tags - generate both for complete coverage.
How big should the share image be?
A landscape image around 1200 by 630 pixels works well across platforms.
Is my input stored?
No - generation happens in your browser.
