About Caching Results

This Tool's Cache

For performance reasons, this tool caches results on the server side for up to 5 minutes. This means:

  • If you check the same URL multiple times in succession, recent changes may not be immediately reflected
  • The cache is automatically refreshed after 5 minutes. For the most up-to-date information, check 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
Common (Standard)1200×630px1.91:1Most widely supported size
X (formerly Twitter)1200×628px1.91:1For large image cards
Facebook1200×630px1.91:1Standard size for posts and shares
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)

About OGP (Open Graph Protocol)

Basic Concept of OGP

OGP stands for "Open Graph Protocol," developed by Facebook in 2010 and subsequently adopted by many social media platforms as a web standard. This system allows web pages to be displayed as rich cards (attractive display formats including images, titles, and descriptions) when shared on social media.

Proper OGP implementation offers several benefits:

  • Enhanced visual appeal: Transformation from text-only display to visually attractive content with images
  • Improved click-through rate (CTR): Studies suggest rich card displays can increase CTR by up to 3 times
  • Strengthened brand recognition: Enhanced brand image through consistent visual representation
  • Content clarification: Content is immediately understandable when shared

How to Implement OGP Tags

To implement OGP tags, add meta tags to the <head> section of your HTML document. Here's the complete implementation method:

Required OGP Tags

Here are the minimal OGP tags you should implement:

<!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 (about 100-150 characters)" />
  <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" />  <!-- can also be article, book, profile, etc. -->
  <meta property="og:site_name" content="Site Name" />
</head>
<body>
  <!-- Page content -->
</body>
</html>

Additional Settings for X (formerly Twitter)

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

For more details, refer to the Official X Developer Documentation.

A: OGP tags are not a direct SEO ranking factor, but they can indirectly benefit SEO through increased social sharing, traffic improvement, and higher engagement rates.
