Introduction
Have you ever shared a link on social media only to find the preview looks terrible — wrong image, missing description, or a cut-off title? That's because social platforms rely on Open Graph (OG) tags to render link previews, and most websites either don't set them properly or don't test them at all. An Open Graph preview tool lets you see exactly how your links will appear on Facebook, Twitter, LinkedIn, Slack, and other platforms before you hit share.
In this guide, we'll walk through what Open Graph tags are, how they work across different platforms, and how to use Risetop's OG image preview tool to ensure your content always looks its best when shared.
What Is Open Graph Protocol?
Open Graph is a protocol created by Facebook in 2010 that allows web pages to become rich objects in a social graph. When you add OG meta tags to your page's <head> section, social media platforms can extract structured information about your page and display it as a rich preview card instead of a plain text link.
Without OG tags, platforms scrape your page and try to guess the title, image, and description. The results are often unpredictable and frequently poor. With proper OG tags, you have full control over your link's appearance across every social platform.
Essential Open Graph Tags
- og:title — The title displayed in the link preview card.
- og:description — A brief description of the page content.
- og:image — The image shown in the preview. Should be at least 1200×630 pixels.
- og:url — The canonical URL of the page.
- og:type — The type of content (website, article, product, etc.).
- og:site_name — The name of your website.
How to Use the OG Preview Tool
Risetop's Open Graph preview tool works in three simple steps:
- Enter your URL — Paste any webpage URL into the input field.
- Preview across platforms — The tool fetches your page's OG tags and renders previews for Facebook, Twitter, LinkedIn, Slack, Discord, and more.
- Identify and fix issues — Missing tags, undersized images, and truncated text are highlighted so you can fix them before sharing.
Unlike manual testing (which requires actually posting links), the preview tool shows you results instantly and side-by-side across multiple platforms.
Step-by-Step Examples
Example 1: Blog Post Preview
<meta property="og:title" content="How to Double Your Traffic in 90 Days">
<meta property="og:description" content="A data-driven strategy that helped us grow from 10K to 20K monthly visitors in just three months.">
<meta property="og:image" content="https://example.com/images/traffic-growth.jpg">
<meta property="og:url" content="https://example.com/blog/double-traffic">
<meta property="og:type" content="article">
<meta property="og:site_name" content="GrowthHub">
When shared on Facebook, this would render a card with the image on the left, the bold title, the description text, and the site name below. On Twitter, it would display as a large image card with the title overlaid at the bottom.
Example 2: Product Page with Twitter Cards
<meta property="og:title" content="Wireless Noise-Cancelling Headphones — SoundPro X1">
<meta property="og:description" content="Premium ANC headphones with 30-hour battery, Hi-Res Audio, and ultra-comfortable memory foam ear cushions.">
<meta property="og:image" content="https://example.com/products/soundpro-x1.jpg">
<meta property="og:type" content="product">
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:title" content="SoundPro X1 — Wireless ANC Headphones">
<meta name="twitter:image" content="https://example.com/products/soundpro-x1-twitter.jpg">
Pro tip: Twitter uses its own twitter:card meta tags but falls back to OG tags if Twitter-specific tags aren't present. For maximum control, set both.
Example 3: Event Page
<meta property="og:title" content="TechConf 2026 — The Future of AI in Business">
<meta property="og:description" content="Join 5,000+ tech leaders at TechConf 2026. September 15-17, San Francisco. Early bird tickets available now.">
<meta property="og:image" content="https://techconf.com/og-banner-2026.jpg">
<meta property="og:type" content="website">
Event pages benefit from large, visually striking OG images that communicate the event's branding at a glance.
| Platform | Image Size | Layout | Special Notes |
|---|
| Facebook | 1200×630px | Horizontal card | Caches previews aggressively — use Facebook Sharing Debugger to refresh |
| Twitter | 1200×600px (large card) | Large image or summary | Requires twitter:card meta tag for large images |
| LinkedIn | 1200×627px | Horizontal card | Has its own Post Inspector for testing |
| Slack | Variable | Inline preview | Very literal OG parsing — errors are visible to teammates |
| Discord | Variable | Embed card | Supports color theming via theme-color meta tag |
Common Use Cases
Content Marketing Campaigns
Before launching any content campaign, preview your links across all target platforms. A single broken OG image can undermine an entire social media campaign. Use the preview tool as a QA step in your publishing workflow.
E-commerce Product Launches
When launching a new product, the social media preview is often the first impression potential customers get. Ensure your product image, title, and key selling points are all visible in the OG preview card.
PR and Media Outreach
Journalists and bloggers frequently share links on social media. If your OG tags are missing or broken, your coverage may look unprofessional. Test before sending press releases.
Newsletter Link Previews
Many email clients now render OG previews for links. Make sure your links look good in email as well as on social media.
OG Image Best Practices
- Use 1200×630 pixels minimum — This is the standard size that works across all major platforms.
- Keep text readable at small sizes — Avoid tiny fonts; many users view these previews on mobile devices.
- Use under 5MB file size — Large images may fail to load on some platforms.
- Use absolute URLs for images — Relative paths won't work when social platforms fetch your tags.
- Use JPG or PNG format — WebP support varies across platforms.
- Test with the actual URL — Always preview before sharing, especially after site updates.
Frequently Asked Questions
Why does Facebook show an old image for my page?
Facebook caches OG data aggressively. Use the Facebook Sharing Debugger to force a cache refresh. LinkedIn and Twitter have similar tools: LinkedIn Post Inspector and Twitter Card Validator.
Do I need both OG tags and Twitter Cards?
For best results, yes. Twitter Cards use their own meta tags (twitter:card, twitter:title, etc.) but fall back to OG tags if Twitter-specific ones are missing. Setting both gives you the most control.
Can I have different OG images for different platforms?
Yes. Set the default with og:image, then override with platform-specific tags like twitter:image. This is useful when platforms have different aspect ratio requirements.
What if my OG image doesn't appear?
Common causes include: relative image URLs (use absolute), robots.txt blocking the image, missing og:image tag, or the image exceeding the platform's file size limit. Use our preview tool to diagnose the issue.
How do OG tags affect SEO?
While OG tags don't directly impact search rankings, they significantly affect click-through rates from social media, which drives traffic and signals to search engines that your content is valuable. They're an essential part of a holistic SEO strategy.
