Facebook Online Checker App

The tool analyzes public Facebook page URLs to verify accessibility and the presence of metadata that influences how pages render in social previews. It performs an HTTP request to determine status and redirects, then parses the HTML to extract the title, meta description, canonical link, and Open Graph tags (og:title, og:description, og:image). Results are reported per URL with a simple quality indicator and actionable findings. This helps social media teams confirm that pages will display proper previews when shared, and SEO teams ensure metadata aligns with brand and campaigns. The approach is automation-focused and non-intrusive, relying only on publicly accessible content. It supports batch checks for multiple pages and produces structured outputs suitable for export or integration with QA pipelines. Unique value lies in combining accessibility, metadata validation, and performance signals into a single, repeatable check that mirrors how Facebook and other platforms will fetch and render a page. Use cases include campaign launches, page relaunches, and ongoing governance of social previews across an index of pages.
