原文外掛簡介
A link shared with no image gets ignored. This plugin shows you, before anyone shares it, exactly what Facebook, LinkedIn, X and WhatsApp will display for a page, and tells you what is missing.
It does not generate Open Graph tags: it checks the ones your site already outputs, whoever put them there. It reads the published page the way a social network does, so it does not care how the page was built: block editor, classic editor, Bricks, Elementor, Divi, a custom theme, Yoast, Rank Math, or nothing at all. If the tags are in the output, it sees them.
Where you find it
In the admin bar, on any page of your site and on any edit screen, so it works inside page builders too.
As a panel in the post editor sidebar.
Under Tools > Social previews, to check the latest published content in one table.
What it checks
Preview image: missing, relative path, or served over http.
Title: missing or too long for the platforms to show in full.
Description: missing, too short, too long, or only inherited from the meta description.
Twitter card.
Alt text for the preview image.
Tags printed twice by the theme and the SEO plugin together, naming which ones.
Your site name repeated at the end of the title, where the platform already shows the domain.
