What are Open Graph tags?

Open Graph (og:) tags control how your page appears when shared on Facebook, LinkedIn, and other social platforms. They set the title, description, and thumbnail image for link previews.

What is a Twitter Card?

Twitter Cards are meta tags that control how your URL looks when tweeted. Summary cards show a small thumbnail, while summary_large_image cards show a large banner image.

What should the meta description length be?

Google typically displays 150–160 characters of the meta description. The generator shows a live character count and highlights if you exceed the limit.

What is a canonical URL?

A canonical URL tells search engines which version of a page is the primary one, preventing duplicate content issues when a page is accessible via multiple URLs.
