Frequently asked questions
Are the previews exact?
They are close: each network has its own layout, cuts and cache. After a fix, a network may keep the old preview for a while.
Which tags are needed at least?
og:title, og:description and og:image (full https address, 1200 × 630 pixels recommended), plus twitter:card for X.
Why can my page not be read?
It is not responding, not a web page, or blocking automated visits.
Is it free?
Yes, free and without an account, within about twenty tests per hour.
