What can I debug with this tool?
This link preview debugging tool inspects and debug metadata HTML markup, ensuring accurate titles, descriptions, and images across all major social networks.
It runs on
Metascraper
, the battle-tested library maintained by Microlink. We don't just regex HTML; we use a flexible rule-based system to normalize metadata from the wildest edge cases on the web.We normalize data into a unified JSON response, prioritizing the most relevant source automatically.
How does social media caching work?
Social networks aggressively cache link previews. This validator fetches the live version of your URL, acting as a "fresh" crawler.
- Agent Spoofing: We simulate the User-Agent of bots (Googlebot, Twitterbot) to show you exactly what they see.
- Rendered HTML: Unlike standard scrapers, we can execute JavaScript to capture meta tags dynamically injected by React/Vue apps.
Update your metadata using our recommended patterns, then re-run the test to verify the fix.
Can I automate this process?
You can automate your Open Graph and SEO audit workflow using the Microlink API. This allows you to programmatically validate metadata for thousands of URLs without manual intervention.
The following examples show how to use the Microlink API with CLI, cURL, JavaScript, Python, Ruby, PHP & Golang, targeting 'https://microlink.io' URL with 'meta' API parameter:

How can I create social media images?
In the era of link unfurling (Facebook, X, LinkedIn, etc.), your og:image is your first impression. Manually designing assets for every dynamic route is unscalable, but generic logos get ignored.
Microlink solves this by treating your screenshots as an Screenshot API.
