Woh 5-6 meta tags jo har social platform ko batate hain ke tumhara link ka preview kaisa dikhna chahiye. 2 minute ka kaam hai aur tum ne nahi kiya. Aaj fix karte hain — step by step, har platform ke liye, complete code ke saath.
What Are Open Graph Tags?
Open graph tags are HTML meta tags that control how your web pages appear when shared on social media platforms. Originally created by Facebook in 2010, the Open Graph protocol has become the universal standard for link previews across virtually every platform — Facebook, LinkedIn, WhatsApp, Telegram, Discord, Slack, iMessage, and more.
When someone shares your URL, the receiving platform's crawler fetches your page and looks for open graph tags in the <head> section. These tags specify the title, description, image, and URL that should appear in the link preview card. Without them, platforms guess — pulling random text, wrong images, or showing nothing at all.
Think of open graph tags as the packaging for your content when it travels outside your website. You control exactly how your pages look in someone's WhatsApp chat, Twitter feed, or LinkedIn post. Given that social sharing drives a significant portion of web traffic, getting this right directly impacts your click-through rate and brand perception.
Check if your pages have proper OG tags right now — run a full site audit and the On-Page SEO report will flag every page with missing or malformed open graph markup.
Why Open Graph Tags Matter for SEO and Marketing
Social Sharing CTR
A link with a compelling image, clear title, and strong description gets dramatically more clicks than a link with a grey placeholder box. Studies show that social posts with optimized preview images receive 150-200% more engagement than posts with missing or default previews.
This isn't just vanity. More clicks from social sharing means more traffic. More traffic signals to Google that your content is valuable and relevant. While social signals aren't a direct Google ranking factor, the secondary effects — increased traffic, lower bounce rate, more backlinks from people who discover your content via social — absolutely influence rankings.
Brand Perception and Trust
When your link previews look professional and intentional, people trust your brand more. A broken preview signals "this site doesn't pay attention to details" — which makes users wonder if the content itself is equally careless.
For agencies, freelancers, and SaaS products, open graph tags are non-negotiable. Every link you share with clients or prospects is a mini-advertisement for your brand. Make it count.
AI and Rich Previews
Modern messaging apps and AI assistants increasingly use OG tags to generate rich previews, summaries, and recommendations. Properly tagged pages get better treatment in AI-powered discovery tools, chat summaries, and link aggregators.
Essential Open Graph Tags (The Core Five)
og:title
The title that appears in the link preview. Should be compelling, clear, and under 60 characters. This can differ from your HTML <title> tag — use it to optimize for social engagement rather than search rankings.
og:description
A 2-3 sentence summary that appears below the title in the preview. Keep it under 200 characters for consistent display across platforms. Make it actionable — tell users what they'll get by clicking.
og:image
The preview image. This is the single most important open graph tag because humans are visual creatures. A strong image dramatically increases click-through rates. Requirements:
- Minimum size: 1200 x 630 pixels (Facebook's recommended ratio is 1.91:1)
- Maximum file size: 8 MB (keep under 1 MB for fast loading)
- Format: JPG or PNG (WebP not universally supported for OG yet)
- Text on images: Keep any text large enough to read on mobile thumbnails
og:url
The canonical URL for the page. This tells platforms which URL to associate with the shared content, preventing duplicate previews for the same content accessed via different URLs.
og:type
Defines the content type. Common values: website (default for most pages), article (for blog posts and news), product (for e-commerce). The type affects how some platforms display the preview.
Twitter Card Tags
Twitter (X) uses its own meta tag system alongside Open Graph. While Twitter falls back to OG tags when its own tags are missing, setting Twitter-specific tags gives you more control over how your content appears on the platform.
The two essential Twitter tags:
- twitter:card — the card type:
summary(small image),summary_large_image(full-width image),player(video), orapp - twitter:site — your brand's Twitter handle (e.g.,
@slapmyweb)
For most content, summary_large_image is the best choice — it displays a full-width image that dominates the timeline and gets more engagement than the small square thumbnail of summary cards.
Generate both OG tags and Twitter Card tags simultaneously using the SlapMyWeb Twitter Card Generator — it outputs the complete set of meta tags you need.

</head>For Next.js apps, use the metadata API instead of raw HTML:
// app/blog/[slug]/page.tsx
import type { Metadata } from 'next';
export async function generateMetadata({ params }): Promise<Metadata> {
const post = await getPost(params.slug);
return {
title: post.title,
description: post.excerpt,
openGraph: {
title: post.title,
description: post.excerpt,
url: `https://example.com/blog/${params.slug}`,
type: 'article',
publishedTime: post.publishedAt,
modifiedTime: post.updatedAt,
images: [
{
url: post.ogImage,
width: 1200,
height: 630,
alt: post.ogImageAlt,
},
],
},
twitter: {
card: 'summary_large_image',
site: '@exampleblog',
title: post.title,
description: post.excerpt,
images: [post.ogImage],
},
};
}OG Image Requirements and Best Practices
The og:image is responsible for the vast majority of social sharing engagement. Get it wrong and your beautifully crafted content gets shared with an ugly grey box.
Sizing guidelines across platforms:
| Platform | Recommended Size | Aspect Ratio |
|---|---|---|
| 1200 x 630 | 1.91:1 | |
| Twitter (large card) | 1200 x 628 | ~1.91:1 |
| 1200 x 627 | 1.91:1 | |
| 1200 x 630 | 1.91:1 | |
| Discord | 1200 x 630 | 1.91:1 |
The universal safe size is 1200 x 630 pixels. Create one image at this size and it works everywhere. Keep important text and visual elements within the center 80% of the image — some platforms crop the edges.
Always include og:image:width and og:image:height properties. Without explicit dimensions, platforms have to download the full image to determine its size, which can delay preview generation or cause it to fail entirely.
Use the SlapMyWeb Open Graph Generator to create the complete tag set with proper image specifications.
Testing and Debugging Open Graph Tags
After implementing your open graph tags, test them before sharing. Each platform caches OG data aggressively, so a bad first impression persists for hours or days.
Testing tools:
- [SlapMyWeb Social Media Preview](/tools/social-media-preview) — see how your URL will appear on Facebook, Twitter, LinkedIn, and WhatsApp simultaneously
- Facebook Sharing Debugger (developers.facebook.com/tools/debug) — preview and clear Facebook's OG cache
- Twitter Card Validator (cards-dev.twitter.com/validator) — verify Twitter card rendering
Clearing cached previews:
When you update OG tags but platforms show old data, you need to clear their cache. For Facebook, paste your URL into the Sharing Debugger and click "Scrape Again." For Twitter, the Card Validator automatically refreshes. For WhatsApp, you may need to wait up to 24 hours or share the URL with a cache-busting parameter.
Common Open Graph Mistakes
Missing og:image or Using a Tiny Image
The single most common mistake. Without og:image, platforms either show nothing or pull a random image from your page (often a logo, icon, or advertisement). Images under 200x200 pixels may be ignored entirely by Facebook and LinkedIn.
Using Relative URLs Instead of Absolute
All open graph tags require absolute URLs. og:image="/images/hero.jpg" won't work — it must be og:image="https://example.com/images/hero.jpg". Same for og:url. This is the second most common implementation error.
Not Setting og:url (Causing Duplicate Previews)
Without og:url, each URL variation (with/without trailing slash, with/without www, with query parameters) generates a separate preview with separate share counts. Set og:url to your canonical URL to consolidate all sharing signals.
Forgetting Twitter-Specific Tags
While Twitter falls back to OG tags, it doesn't support all of them equally. Without twitter:card, Twitter defaults to the small summary card type even if you have a beautiful 1200x630 og:image. Always set twitter:card to summary_large_image for maximum visual impact.
Not Adding og:image:alt
Accessibility matters everywhere, including in social previews. The og:image:alt and twitter:image:alt tags provide alternative text for screen readers and improve the content's metadata quality signal for platform algorithms.
FAQ
Do open graph tags directly affect Google search rankings?
Open graph tags don't directly influence Google's search rankings. However, they indirectly impact SEO through increased social sharing, higher referral traffic, and more backlink opportunities. Google also uses og:image for Google Discover recommendations, making open graph tags relevant for visibility beyond traditional search.
Can I use different titles for OG and SEO?
Yes, and you often should. Your HTML <title> tag should be optimized for search intent and include target keywords. Your og:title should be optimized for social engagement — more conversational, curiosity-driven, and compelling. A page can have a keyword-focused SEO title and a click-worthy social title simultaneously.
How often should I update my OG images?
Update OG images when you significantly refresh content, rebrand, or when A/B testing reveals low social engagement. For evergreen content, create strong OG images once and leave them. For time-sensitive content (annual guides, trend reports), update images to reflect the current year or data.
What happens if og:image fails to load?
If the image URL returns a 404 or times out, platforms show a blank preview or pull a fallback image from your page. This is especially problematic because platforms cache the failure — even after you fix the image URL, the broken preview persists until you manually clear the cache. Always verify image URLs are accessible before deploying OG tags.
