About Result Caching

This Tool's Cache

This tool caches results server-side for up to 5 minutes to improve performance:

  • When checking the same URL repeatedly, the latest changes may not be immediately reflected
  • Cache is automatically refreshed after 5 minutes. To check the most up-to-date information, please try again after 5 minutes

Social Media Platform Caching

Each social media platform also maintains its own cache of OGP information, so changes to your webpage's OGP settings may not be immediately reflected when shared on these platforms.

OGP Optimization Guide

Appropriate OGP Image Sizes

OGP images have optimal sizes according to each social network's specifications. Using inappropriate sizes may result in images being cropped or distorted, diminishing their visual appeal.

Recommended sizes as of 2025:

Social Media PlatformRecommended SizeAspect RatioNotes

X (formerly Twitter)1200×628px1.91:1For large image cards

LinkedIn1200×627px1.91:1Similar to Facebook
Pinterest1000×1500px2:3Vertical images are more effective

Important points about image size:

  • Minimum size: Use at least 600×315px (smaller images may be displayed in reduced size)
  • File size: Keep under 5MB for improved load times
  • Image quality: Use crisp images with minimal text
  • Important elements: Position them centrally (elements at the edges may be cropped)

Troubleshooting

Common Errors and Solutions

"URL error or analysis failure occurred"

  • Check if the site is accessible
  • Try again after some time

OGP Configuration Best Practices

Recommended practices for effective OGP configuration:

  • Image size: Use high-quality images 1200×630px or larger
  • Title: Set an attractive title within 60 characters
  • Description: Clearly describe content within 160 characters
  • URL format: Write all URLs as absolute URLs (starting with https://)

Verification Steps

  1. Check metadata configuration status with this tool
  2. Clear cache with official social media debuggers
  3. Test with actual social media posts

For X, you can also configure Twitter Cards with specialized tags:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Page Title</title>

  <!-- Basic OGP tags -->
  <meta property="og:title" content="Page Title" />
  <meta property="og:description" content="Concise description of the page" />
  <meta property="og:url" content="https://example.com/page-url" />
  <meta property="og:image" content="https://example.com/image-url.jpg" />
  <meta property="og:type" content="website" />
  <meta property="og:site_name" content="Site Name" />

  <!-- Tags for X (Twitter) Cards -->
  <meta name="twitter:card" content="summary_large_image" />
  <meta name="twitter:site" content="@YourXAccountName" />

  <!-- The following can be omitted if OG tags are already present -->
  <meta name="twitter:title" content="Page Title" />
  <meta name="twitter:description" content="Page description" />
  <meta name="twitter:image" content="https://example.com/image-url.jpg" />
</head>
<body>
  <!-- Page content -->
</body>
</html>

Important Notes:

  • Use absolute URLs for all image and URL properties
  • The prefix attribute on the <html> element is no longer required for modern platforms
  • Test your implementation using validation tools after setup

X (Twitter) Cards mainly come in these types:

  • summary: Card with a small square image
  • summary_large_image: Card with a large landscape image (most common)
  • app: Card promoting app installation
  • player: Card for video or audio content
