CohesionStack — metadata packs in minutes

Submit a list of links and get a compact, reviewable package: a CSV of extracted metadata plus the downloaded images and favicons used to render previews. Teams use the output to audit previews, assemble media packs, or prepare content for publishing and campaigns.

Open Graph (OG) meta tags are small snippets in a page's HTML that suggest which title, description and image to use when a link is shared. They help platforms and tools show a consistent, attractive preview for links.

OpenGraph tags are metadata embedded in a webpage's HTML that help control how the page appears when shared on social media platforms. They specify the title, description, image, and other attributes of the shared content.

When a URL is shared, social platforms and many crawlers look for OG and Twitter Card metadata (and sometimes JSON-LD) to build the card: title, description and image. Collecting those tags and the actual image bytes makes it easier to diagnose and fix preview problems.

This approach is aimed at batch work and handoffs: quickly review metadata across many links, bundle the images and favicons, and hand the ZIP to designers, editors or analytics teams. If you only need a single link preview for occasional checks, lightweight preview tools may be sufficient.

The CSV columns capture OG/Twitter/JSON-LD fields, fetch URLs, HTTP status, and media dimensions. Use filters in a spreadsheet or import into your CMS to find missing images, inconsistent titles, or broken links — then re-run after fixes to confirm changes.

When an image or favicon is downloaded and saved for a run you'll see a run-relative path (for example images/foo.png). Click the thumbnail to open the served asset. If it doesn't load in your browser, follow the Troubleshooting checklist below (refresh, open in a new tab, clear cache, try another browser/device, confirm the preview link) and share the failing URL with the preview host if it still fails.

If an image or favicon appears missing (404), try these steps in order:

1. Refresh the page (press Ctrl/Cmd+R).
2. Open the thumbnail or image in a new tab (right‑click → "Open image in new tab") to see the direct asset URL.
3. Clear your browser cache or try a private/incognito window to rule out caching issues.
4. Try a different browser or device on the same network to check if it's local to your browser.
5. Confirm you're using the exact preview link you were given ("localhost" only works if you're on the hosting machine).
6. If the asset still doesn't load, take a screenshot and copy the failing asset URL into a message for the person who shared the preview; include the run ID if visible.
