Share preview
When someone pastes your link in a post or a message, the network reads a few hidden tags to build the card. See what they show, and what to fix before you share.
The tags that matter
og:image
The image
1200 × 630 px, JPEG or WebP, under 300 KB. Keep text away from the edges: some networks crop.
og:title
The title
Written for people, not for Google: what will they get by clicking?
og:description
The description
One or two sentences. Facebook shows about two lines, Google about 155 characters.
After a change
Facebook, LinkedIn and messaging apps keep the preview in memory. Once your tags are fixed, paste the address into Facebook's Sharing Debugger or LinkedIn's Post Inspector to force them to read it again.
On WordPress, an SEO plugin (Yoast, Rank Math, SEOPress) writes these tags for you: set a default image in its settings and a specific one on important pages.
Frequently asked questions
What does my link look like when it is shared?
Enter the page address: the tool reads the Open Graph and X tags hidden in the page, then shows the card as it will appear on Facebook, LinkedIn, X, iMessage, Slack and Google, along with what to fix.
What image do I need for a good preview?
Aim for an og:image of 1200 × 630 px, in JPEG or WebP, under 300 KB. Keep text away from the edges, because some networks crop the image.
I fixed my tags but the old preview still shows. Why?
Facebook, LinkedIn and messaging apps keep the preview in memory. Paste the address into Facebook's Sharing Debugger or LinkedIn's Post Inspector to force them to read the page again.
