Complete Meta Tags Generator

You paste your site link into WhatsApp and get a bare URL — no title, no image, nothing. On LinkedIn it renders as a grey rectangle. The cause is almost always the same: no Open Graph block in the head, or one that points at a relative image path, which no crawler will resolve. Typing those lines from scratch under deploy pressure is where the typos come from.

Seven inputs produce sixteen lines: charset, viewport, theme-color, title, description, canonical, five og properties and five twitter ones. Values are escaped for &, < and quotes, so an ampersand in the title will not break it. Two conventions worth knowing: og:type is hard-coded to website (switch it to article on posts) and twitter:card is fixed at summary_large_image. The language field feeds og:locale only, and Open Graph expects an underscore there, en_US, not the hyphenated form prefilled in the box.

The tool summary mentions hreflang, but the generated block contains no link rel=alternate hreflang line at all — that stays manual, one line per language plus x-default. It also omits the html lang attribute and the robots meta. Your image must be an absolute URL, ideally 1200 by 630. After pasting, run the page through the Facebook sharing debugger to force a cache refresh. It all runs in the browser; nothing leaves your machine.
