Frequently Asked Questions
Everything you need to know about Open Graph images, checking your tags, and generating new designs.
OG Image Checker
What is an Open Graph image?
An Open Graph (OG) image is the preview image that appears when you share a link on social media platforms like Twitter, LinkedIn, Facebook, and Slack. It's defined using the og:image meta tag in your page's HTML head. A good OG image increases click-through rates and makes your links stand out in social feeds.
How do I check my website's OG tags?
Enter your URL in the checker and click 'Check OG'. LinkGlow will fetch your page, extract all Open Graph meta tags (og:title, og:description, og:image, og:url), and show you exactly how your link will appear when shared on different platforms.
What OG image size should I use?
The recommended OG image size is 1200x630 pixels with a 1.91:1 aspect ratio. This works well across all major platforms. Keep important content in the center 800x400 safe zone, as some platforms crop the edges.
Why isn't my OG image showing when I share my link?
Common reasons include: the og:image meta tag is missing or has a typo, the image URL is relative instead of absolute, the image file is too large (keep under 8MB), the image format isn't supported (use JPG or PNG), or your server blocks social media crawlers. Use the checker to diagnose the issue.
How often do social platforms refresh OG images?
Each platform has different caching behavior. Twitter caches for about 7 days, Facebook for 24 hours, and LinkedIn for 7 days. You can force a refresh using each platform's debugging tool: Twitter Card Validator, Facebook Sharing Debugger, or LinkedIn Post Inspector.
AI OG Image Generator
How does the AI OG image generator work?
Enter any URL and LinkGlow's AI analyzes your page content, brand colors, and messaging to generate four unique Open Graph image designs. Each image is optimized at 1200x630 pixels for perfect display across all social platforms.
Can I customize the generated OG images?
The AI generates four different design variations for each URL. You can download any of them and use them directly, or use them as inspiration for your own designs. Each generation costs 4 credits.
What makes a good OG image?
The best OG images have a clear headline, brand colors, readable text at small sizes, and a visual that represents the page content. Avoid clutter — the image appears as a small thumbnail in most feeds. Our AI follows these best practices automatically.
How many credits does it cost to generate OG images?
Each generation produces 4 image variations and costs 4 credits (1 credit per image). New accounts start with 12 free credits. You can purchase more credits from our pricing page.
