Frequently Asked Questions
What are open graph tags?
Open graph tags are meta tags in your page's HTML, like og:title, og:description and og:image. LinkedIn, Facebook, Slack and most messaging apps read them to build the preview card when someone shares your link.
What size should my og:image be?
Use 1200 × 627 px (a 1.91:1 ratio). That works for LinkedIn, Facebook and X. Images under 600 px wide may show as a small thumbnail, and other ratios get cropped. Keep important text away from the edges.
Why is LinkedIn still showing my old preview?
LinkedIn caches previews for about 7 days. After you change your tags, paste the URL into LinkedIn's Post Inspector to refresh it. Facebook has a similar Sharing Debugger.
Do I need separate tags for X (Twitter)?
Mostly no. X falls back to your open graph tags for the title, description and image. The one tag you do need is twitter:card set to summary_large_image, otherwise X shows a small square preview.
Do open graph tags help SEO?
Not directly, since Google doesn't use them to rank pages. But a clear title and a strong image get more clicks and shares on social and in chat apps, which brings traffic and links that do help.
