Questions
What are Open Graph tags?
Meta tags that tell Facebook, LinkedIn, WhatsApp, Slack and others what to show when someone shares your page — the headline, the blurb and the image. Without them each platform guesses from the page, and the guess is often an unhelpful crop and the wrong sentence.
Which Open Graph tags actually matter?
og:title, og:description and og:image do nearly all the work. og:url helps consolidate shares of the same page under one address, and og:type tells platforms what kind of thing they're showing. The rest is optional.
Why isn't my image showing when I share the page?
The two usual causes are a relative og:image URL (platforms need an absolute one starting with https://) and a cached preview from before you added the tag. This tool catches the first. For the second, use the platform's own debugger to force a re-scrape.
Do I need Twitter card tags as well as Open Graph?
Not strictly — X falls back to Open Graph when Twitter tags are absent. But without twitter:card you usually get a small preview instead of a large one, which is a meaningful difference in how much space your link takes up in a feed.
Do Open Graph tags help SEO?
Not as a ranking signal. They affect how often a shared link gets clicked, which drives real traffic and, indirectly, the kind of engagement and linking that does matter.
