01 / How it works
Checked in seconds, no AI needed
01
We read your tags
Open Graph and Twitter card tags from your page's HTML.
02
We render the card
A preview of how your link shows up when shared.
03
We check the image
That the preview image exists and loads.
02 / What works
What works, and why
A 1200×630 preview image
That size displays sharply on X, LinkedIn, Slack and Facebook without awkward cropping.
A title written for sharing
The og:title can be shorter and punchier than your SEO title, since people see it in a feed.
summary_large_image on X
It shows the big image card instead of a small thumbnail, which gets far more attention.
03 / What to avoid
What doesn't work, and why
No og:image
Shared links show as a bare grey box or plain URL, which few people click.
Relative image URLs
og:image needs a full https:// URL, or most platforms can't load it.
04 / FAQ
Questions
What are Open Graph tags?
Meta tags like og:title, og:description and og:image that tell social platforms and chat apps what to show when someone shares your link.
I fixed my tags but the old preview still shows. Why?
Platforms cache previews. LinkedIn's Post Inspector and similar tools can refresh it, and new shares usually pick up the change.
