What Is a Meta Tag Generator?
A Meta Tag Generator helps you create HTML meta tags for your web pages. Meta tags provide structured metadata about your page to search engines (SEO), social media platforms (Open Graph, Twitter Cards), and browsers (viewport, charset, theme color). They are placed inside the <head> section of an HTML document and play a crucial role in how your website appears in search results and when shared on social networks.
This tool generates standard meta tags (title, description, keywords, author, robots, viewport), Open Graph tags for Facebook and LinkedIn sharing, Twitter Card tags, and other common tags like canonical URL and theme color. All sections are optional and can be toggled on or off to produce exactly the meta tags you need.
Common use cases include preparing SEO metadata for new web pages, ensuring correct social media previews when sharing links, generating complete <head> content for static site generators, and auditing existing pages for missing meta tags.
Meta Tag Reference

Frequently Asked Questions
Which meta tags are essential for SEO?
At minimum, every page should have a title tag and meta description. For social sharing, add og:title, og:description, og:image, and twitter:card.
How long should my meta description be?
Aim for 155-160 characters. Google typically displays up to 160 characters in search results. Longer descriptions will be truncated.
What is Open Graph and why do I need it?
Open Graph is a protocol that enables rich social sharing previews on Facebook, LinkedIn, and other platforms. When you share a link with OG tags, the platform displays a title, description, and image card instead of just a plain URL.
Is this tool safe to use?
Yes. All processing happens entirely in your browser. No data is sent to any server.
How do I verify my meta tags work correctly?
Use the Facebook Sharing Debugger or Twitter Card Validator to preview how your tags appear when shared. Our Meta Tag Reference table above also helps you understand each tag's purpose.
