Page with no data for sharing on social networks
When someone shares your link, every network and every app decides for itself what to show. The image and the headline you appear with are not yours to choose.
When we count it as met
When we measure the same pages again, all of them declare at least one Open Graph tag. We check that there is one, not which ones.
How to check it yourself
Confirm it in the page head: the Open Graph tags appear.
Measure it on your site
UXMachine measures it in a real browser, on desktop and mobile, together with the other checks.
