Description
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.
FAQ
-
Does it work with my page builder?
-
Yes. It reads the final HTML of the published page, not the editor, so every builder is supported.
-
Does it change my site?
-
No. It only reads. Fix the issues wherever you set them today: your SEO plugin, your theme or the featured image.
-
A page times out
-
The plugin waits 30 seconds for your site to answer itself. If a template makes its own remote calls, that can take longer. Raise the wait with the
cardlens_request_timeoutfilter, or better, cache those calls. -
Why does it say the page must be published?
-
Social networks can only read a publicly reachable URL, and so does this plugin.
-
The preview looks outdated
-
Results are cached for five minutes. Use “Check again” in the preview window to force a fresh read. Facebook and LinkedIn also keep their own cache: use their official debuggers to refresh it.
