How Link Previews Boost Your Click-Through Rate

Understanding the basics
How Link Previews Work
Link previews are generated using the Open Graph protocol — a set of meta tags that tell social platforms how to display your content. Without these tags, platforms may show a blank card or pull incorrect information from your page. Sharing links offline? Create a URL QR code to make any link scannable — and learn the difference between static vs dynamic QR codes to pick the right type for your use case.
- You Share a URL
- When you paste a link on Facebook, X, LinkedIn, or any social platform, the platform's crawler visits your page to fetch metadata.
- Crawler Reads Meta Tags
- The crawler looks for Open Graph tags (og:title, og:description, og:image) and Twitter Card tags in your page's <head> section to build the preview.
- Preview Card Is Generated
- The platform uses these meta tags to render a rich preview card with your page's title, description, and image — what your audience sees before they click.

Troubleshooting
Common Link Preview Issues & How to Fix Them
Having trouble with your link previews? Here are the most common issues and how to resolve them quickly.
Marketing impact
Why Link Previews Matter for Marketing
Link previews aren't just a nice-to-have — they directly impact your marketing performance. Studies show that social posts with properly configured Open Graph images see 2-3x higher click-through rates compared to posts with missing or broken previews. When your audience scrolls through their feed, the preview card is your first impression.
For marketers running campaigns across multiple channels, consistent link previews ensure your brand looks professional everywhere — whether someone shares your link on Facebook, pastes it in a Slack channel, or posts it on LinkedIn. A broken preview with a missing image or wrong title undermines trust before the user even clicks.
Link previews also play a role in SEO. When your pages are shared on social media with rich, clickable preview cards, they earn more engagement signals. More clicks, more shares, and more time on your content — all of which correlate with improved search rankings over time.
If you're already optimizing your link previews, consider the full picture: when you create a social media QR code for your profiles or share URLs via dynamic QR codes, the landing page preview matters just as much. A scannable code that leads to a page with broken OG tags creates a poor first impression. Use this tool to check every URL before you share it — whether digitally or in print.
