About This Tool
Twitter Card meta tags allow social media crawlers (such as the Twitter / X web bot) to display rich visual media previews, article headlines, and publisher summaries when links are shared. This browser-based inspector extracts and verifies your raw HTML <head> meta markup to confirm all required Twitter Card directives are formatted properly before deploying pages to production.
### How the Parser Evaluates Twitter Markup
The tool scans pasted HTML source code using regex pattern matching: - **twitter:card:** Detects the preview layout directive, commonly `summary` or `summary_large_image`. - **twitter:title:** Extracts the headline text (optimal under 70 characters). - **twitter:description:** Parses the summary copy displayed beneath the card image (recommended 150-200 characters). - **twitter:image:** Identifies the direct URL path to the preview thumbnail graphic (recommended 1200x630 pixels for large cards).
### Worked Parsing Example
Pasting the following HTML header snippet into the editor: ```html <meta name="twitter:card" content="summary_large_image"> <meta name="twitter:title" content="Electric Vehicle Charging Station Directory"> <meta name="twitter:description" content="Locate fast DC charging stations nationwide with real-time port availability and route planning."> <meta name="twitter:image" content="https://example.com/assets/ev-hero-card.jpg"> ```
The parser immediately extracts and structures the tags: - **Card:** `summary_large_image` - **Title:** `Electric Vehicle Charging Station Directory` - **Description:** `Locate fast DC charging stations nationwide with real-time port availability and route planning.` - **Image:** `https://example.com/assets/ev-hero-card.jpg`
### Pure Client-Side Parsing Note
The parser runs entirely inside your browser using client-side JavaScript regex extraction. No HTML documents, proprietary page templates, or unpublished staging URLs are sent across the network.
How to Use
- 1
Copy the <meta name="twitter:..."> tags or the complete <head> block from your web page.
- 2
Paste the HTML snippet into the input text area.
- 3
Inspect the extracted Card type, Title, Description, and Image URL lines in the output preview.
- 4
Verify that all tags contain non-empty values and match your target social preview specifications.
Frequently Asked Questions
What is the difference between summary and summary_large_image card types?
A summary card displays a small square thumbnail image to the left of the title and description, whereas summary_large_image features a prominent full-width banner image above the text.
Why should I define both Open Graph (og:) and Twitter Card meta tags?
While Twitter / X falls back to Open Graph tags (og:title, og:image) when Twitter tags are missing, explicitly declaring twitter:card is mandatory to enable the large banner preview layout.
Is my pasted source code transmitted to remote servers?
No. Tag parsing occurs 100% locally in your web browser. No HTML code, domains, or metadata strings leave your device.
