About Signet
Signet builds the head-tag markup a page needs for search engines and social sharing: title, description, canonical link, Open Graph, and Twitter Card tags. Fill in the fields, watch the preview update, and copy the finished block into your page's <head>.
Features
- Basic SEO tags: title, description, robots, canonical
- Full Open Graph set for Facebook, LinkedIn, and more
- Twitter Card tags with automatic fallback to Open Graph values
- Character counters that flag when a title or description runs long
- Live search-result and social-card previews

How to use it
- Fill in the Basic tab with your title, description, and canonical URL.
- Switch to Open Graph and Twitter Card to add sharing details, or leave them blank to reuse the Basic values.
- Check the preview cards to see how the page might appear in search and on social feeds.
- Copy the generated tags and paste them into your page's
<head>.
Frequently asked questions
Why do title and description have character counters?
Search engines typically truncate titles beyond about 60 characters and descriptions beyond about 160, so the counters turn red once you pass a length that's likely to get cut off in results.
Do I need to fill in Open Graph and Twitter separately?
No — if you leave those fields blank, Signet reuses your Basic title, description, and canonical URL automatically, so filling in just the Basic tab still produces complete tags.
What image size works best for sharing previews?
Most platforms display Open Graph images at roughly a 1.91:1 ratio, so an image around 1200 by 630 pixels tends to display cleanly across Facebook, LinkedIn, and similar feeds.
Where do these generated tags go?
They belong inside the <head> section of your HTML page, alongside your existing title and stylesheet links.
Is my data uploaded anywhere?
No. The tags are assembled locally in your browser from what you type, and nothing is sent to a server or stored once you leave the page.
