§05 — FAQ
Questions, briefly answered.
Everything you need to know before you paste a URL.
01 What does an Open Graph Checker do? +
It fetches a public URL, parses the HTML, and reports whether the Open Graph and Twitter Card meta tags are present, correct, and ready for social previews across platforms like X, Facebook, LinkedIn and Discord.
02 Is my URL data stored? +
No. Anonymous checks are cached in memory for 10 minutes to reduce duplicate work. The website never stores fetched HTML on disk. Your last URL is only used to render the result.
03 How is the score calculated? +
We evaluate deterministic checks across OG tags, the OG image, Twitter cards and technical metadata. Each check has a fixed weight, and the score is the sum of earned weight expressed as a percentage from 0 to 100.
