About meta tags & Open Graph
The HTML head of a page carries metadata that controls how search engines and social platforms render that page. The classic tags — title and meta description — drive how the result looks in Google. Open Graph tags (og:title, og:description, og:image) control link previews on Facebook, LinkedIn, Slack, Discord, iMessage, and most messaging apps. Twitter Cards add a second layer that X uses for richer previews.
Missing or mis-sized Open Graph images are the most common share-preview problem. Facebook\'s recommended og:image size is 1200×630 pixels, and most platforms reject images smaller than 200×200 or larger than around 5 MB. This tool fetches the URL, parses the head, and surfaces every relevant tag — including OG, Twitter, canonical, and JSON-LD — so you can see exactly what crawlers see.
Frequently asked questions
What is a meta description?
A short summary tag in the HTML head that search engines use as the snippet under the page title in results. It does not directly affect ranking but materially affects click-through rate.
What is Open Graph?
A small set of meta tags (og:title, og:description, og:image, og:url, og:type) defined by Facebook and adopted by most social and messaging platforms to control link preview appearance.
How long should a meta title be?
Roughly 50 to 60 characters. Google truncates titles around 580 pixels of width, which works out to about 60 characters in most cases. Shorter is usually better.
Why aren't my Open Graph tags showing up?
Most platforms aggressively cache previews. After updating tags, force-refresh the cache with Facebook's Sharing Debugger, LinkedIn's Post Inspector, or Twitter's Card Validator. Also confirm the tags are present in the raw HTML, not injected by client-side JavaScript.
