Why link previews matter more in India
A huge share of discovery in India happens in WhatsApp groups, Instagram DMs and LinkedIn feeds. When someone pastes your URL, the app reads your Open Graph tags to build a card: image, title, description and site name. A missing or broken image turns a rich card into a plain blue link, and click-through drops accordingly.
How to read the results
The preview switches between approximate WhatsApp, Facebook, LinkedIn and X layouts using the tags we found. Each platform falls back differently when tags are missing, so the checks list exactly which ones exist. We also download the start of your og:image to read its real pixel dimensions and file size — the two most common reasons a preview looks blurry, cropped or doesn't appear at all.
Open Graph best practices
- Set the core four on every page: og:title, og:description, og:image and og:url. Add og:site_name and og:type for completeness.
- Write titles for humans. og:title can be punchier than your SEO title — under 60 characters, without the brand suffix.
- Use absolute https image URLs that are publicly reachable. Images behind login, hotlink protection or bot-blocking firewalls won't load in previews.
- Design for small sizes. Large type, high contrast, one focal point. Many people see your card at thumbnail size on a phone.
- Make product and article pages unique. Templates that reuse the homepage image everywhere waste the opportunity to show what the link is actually about.
- Add twitter:card = summary_large_image so X uses a large image layout.
Open Graph also feeds some AI assistants' link cards. To check the rest of your AI-readiness, run the AI Visibility Checker.
Frequently asked questions
What size should og:image be?
1200×630 pixels (a 1.91:1 ratio) works across Facebook, LinkedIn, X and WhatsApp. Keep important text and logos away from the edges, since some apps crop to a square, and keep the file under about 300 KB so WhatsApp shows it reliably.
I updated my tags but the old preview still shows. Why?
Platforms cache previews. Use Facebook's Sharing Debugger or LinkedIn's Post Inspector to force a re-scrape. WhatsApp caches per chat and usually refreshes within a day, or when the URL changes, for example by adding a query string.
Do I need Twitter card tags if I have Open Graph?
X falls back to og:title, og:description and og:image, but it needs twitter:card to choose the layout. Add twitter:card set to summary_large_image for a big image preview.
