Privacy And Limitations
Meta tag validation runs locally in your browser and does not fetch URLs.
- This parser checks syntax patterns, not live crawler rendering behavior.
- Platform caches and policy changes can still alter final preview output.
- Tag validity does not replace image quality and content relevance.
FAQ
What fields are considered required?
At minimum, title, description, URL, and image are recommended for consistent previews.
Should OG and Twitter titles match?
Usually yes for consistency, unless there is a platform-specific messaging reason.
Can this emulate social crawler output?
No. It validates tag blocks but does not replicate platform rendering engines.
Does it fetch remote pages?
No. Paste the tag snippet directly for local analysis.
Will passing this test guarantee rich cards?
No. Cards depend on crawler access, cache state, and platform rules.
