Frequently Asked Questions
What are Open Graph (OG) tags?
Open Graph tags are meta properties introduced by Facebook that web developers put in the head of a webpage to control how it compiles its thumbnail, title, and preview structure when shared on social apps.
Why does this scraper return a different image than my browser?
It parses the static HTML headers immediately returned by the target server. If your website is a single-page app (SPA) that loads content dynamically via JS, raw crawlers may see empty structures unless you use pre-rendering or SSR.
Why are some fields missing?
If the webpage does not explicitly declare tags like `og:image` or `twitter:description`, we fall back to standard HTML structures (like <title> or <meta name="description">).
