Generate and Preview Social Media Meta Tags Instantly
Meta Tag / OG Preview Generator helps you create, preview, and validate Open Graph and Twitter Card meta tags before deploying your page. Enter your page details, see a live visual mockup of how the share card will look on Facebook and Twitter, and copy the ready-to-use HTML.
Why Meta Tags Matter for SEO and Engagement
Proper Open Graph tags boost click-through rates by controlling exactly how your content appears in social feeds. A well-crafted preview card with a compelling title, clear description, and high-quality image can significantly increase shares and engagement. This tool takes the guesswork out of formatting the HTML correctly.
Frequently Asked Questions
Q:What are Open Graph meta tags?
Open Graph (OG) meta tags are HTML snippets that control how a webpage appears when shared on social media platforms like Facebook, LinkedIn, and Twitter. They define the title, description, image, and URL that get displayed in a link preview card. Without OG tags, platforms fall back to guessing this content, often giving poor results.
Q:What is the difference between OG tags and Twitter Cards?
Open Graph tags (og:*) are the standard protocol used by Facebook, LinkedIn, and many other services. Twitter Cards use both OG tags (twitter:title, twitter:description, twitter:image fall back to og:*) and their own namespaced tags (twitter:card, twitter:site). For best results you should include both — this generator produces both sets automatically.
Q:How can I test if my OG tags are working?
Use platform-specific debuggers: Facebook Sharing Debugger (developers.facebook.com/tools/debug), Twitter Card Validator (cards-dev.twitter.com/validator), and LinkedIn Post Inspector (linkedin.com/post-inspector). These tools fetch your URL and show exactly how your tags are being parsed. Paste your URL into any of these to verify the output matches your intent.
Q:What size should my OG image be?
The recommended OG image size is 1200x630 pixels with a 1.91:1 aspect ratio. Images should be under 8 MB and use JPEG or PNG format. Facebook recommends images with <20% text overlay for optimal display. Twitter large-card images also use 1200x630, while small-card images use 800x400.
Q:Do I need a trailing slash in my og:url?
Yes, or be consistent. The og:url should exactly match the canonical URL of the page — including or excluding the trailing slash. Inconsistency can confuse social crawlers and lead to duplicate shares. If your site uses trailing slashes, include one in og:url. If it does not, omit it.
