How to Use the Meta Tag Previewer
- Type your intended page title (counter shows characters against a 60-character limit, optimal 50–60).
- Type your intended meta description (counter shows characters against a 160-character limit, optimal 150–160).
- Enter the page URL, an Open Graph image URL, your site name, and your Twitter handle (without the @).
- Review the Google Search Preview and Social Media Preview mockups that appear once title and description are filled in.
- Copy the Generated Meta Tags block and paste it into your page’s <head> section.
What is a Meta Tag Previewer?
This previewer shows a live character counter against the two limits that matter most for search snippets — 60 characters for title (optimal 50–60) and 160 for meta description (optimal 150–160) — updating as you type so you can trim copy before it gets cut off in real search results. Below the inputs, a Google Search Preview mockup renders your URL, title, and description in the familiar blue-link layout, and a Social Media Preview mockup shows how the same content plus your image would appear as a shared card.
Once title and description are filled in, a Generated Meta Tags panel produces a complete, ready-to-paste HTML block covering the basic title/description tags, Open Graph tags (title, description, url, type, image, site_name), Twitter Card tags (summary_large_image, title, description, site, image), plus viewport and charset tags — all copyable with one click. A Load Sample Data button fills every field with example values so you can see the full preview flow immediately.
Search engines and social platforms read specific meta tags to build the preview cards users see before clicking — <title> and the description meta tag for search results, and Open Graph / Twitter Card tags for social shares. Getting these right before publishing avoids truncated titles, missing images, or generic fallback text appearing when your page is shared. This tool is a manual preview-and-generate workbench: you type the values you plan to use, and it shows you exactly how they will likely render and gives you the tag markup to paste into your page head.
How it works
You set code, css values, or structured text in the editor in the live panel. Meta Tag Previewer then preview how your website appears in search results and generate SEO meta tags. Results show as formatted / generated code you can copy.
To create SEO-friendly URLs for your pages, use our URL Slug Generator.
Usage scenarios
- Pre-publish SEO check: Draft a title and description, watch the character counters, and adjust wording until both fit within the optimal ranges before publishing.
- Social share preview: Confirm the OG image and description will render as expected in a social card before a link gets shared widely.
- Meta tag handoff to developers: Fill in all fields, then copy the generated tag block directly into a ticket or pull request instead of hand-writing the HTML.

Frequently Asked Questions
What are meta tags and why are they important?+
Meta tags provide information about your webpage to search engines and social media platforms. They control how your content appears when shared, improving click-through rates and SEO.
What's the difference between Open Graph and Twitter Cards?+
Open Graph is used by Facebook, LinkedIn, and other platforms, while Twitter Cards are specific to Twitter. Both control how your content appears when shared.
What image size should I use for social sharing?+
Recommended sizes are 1200x630 pixels for Facebook/Open Graph and 1200x600 pixels for Twitter Cards. Images should be under 1MB for optimal loading.
How do I add meta tags to my website?+
Copy the generated meta tags and paste them in the <head> section of your HTML document, before the closing </head> tag.

When to Use Meta Tag Previewer
- Drafting and checking title/description length before publishing a new page

Tips
- Front-load your most important keywords in the title, since search engines and readers scan the first several words first.
- Keep descriptions action-oriented — this tool shows you the space you have, but the wording still needs to earn the click.
- Always fill in the OG image field before checking the social preview, since platforms fall back to generic or blank cards without one.
Common Mistakes
Assuming this tool reads your live, already-published page — it only previews the values you manually type into the fields.
Leaving the OG image field blank and being surprised the social preview shows no image.
Writing a title right at 60 characters without checking how it looks — some platforms truncate slightly before the hard character limit.
Summary
Type your title, description, and image details above to see exactly how your page will likely appear in Google search and on social cards — then copy the generated tag block straight into your page head.
