How Social Preview Tester Works

The tool utilizes a server-side proxy to bypass CORS restrictions and fetch the raw HTML of your target URL. It parses the document head for specific meta properties (`og:title`, `og:image`, `twitter:card`, etc.). It then feeds this data into pixel-perfect CSS replicas of the Facebook, X (Twitter), LinkedIn, and Google Search feed layouts, immediately highlighting missing tags or cropped images.

Key Features of Social Preview Tester

Pixel-perfect visual simulations for Facebook, X (Twitter), LinkedIn, and Google.

Interactive metadata editor to tweak titles and descriptions in real-time before updating your actual code.

Detailed tag extraction report highlighting missing or malformed Open Graph properties.

Server-side fetching to accurately simulate how external bots view your website.

Practical Application & Code Integration

Use-Case Context

Social preview cards (OpenGraph and Twitter Cards) are the primary drivers of organic click-through rates (CTR) on platforms like X, LinkedIn, and iMessage. Missing or improperly sized `og:image` tags cause platforms to fall back to generic link previews, drastically reducing user engagement and viral coefficient.

Common Questions About Social Preview Tester

What is an Open Graph (OG) tag?

Open Graph is a protocol originally created by Facebook that allows web pages to become 'rich objects' in a social graph. By adding `<meta property='og:title' content='...'>` to your HTML, you dictate exactly what title, description, and image social networks will use when generating a preview card.

What is the best size for an OG Image?

The industry standard size for a social sharing image is 1200 x 630 pixels. This 1.91:1 aspect ratio ensures the image spans the full width of the feed on Facebook, LinkedIn, and X (Twitter) without vertical cropping.

Why doesn't my new image show up when I share the link?

Social networks heavily cache metadata. If you change your `og:image`, Facebook or LinkedIn might still show the old one for days. You must force the networks to clear their cache by running your URL through the official Facebook Sharing Debugger or LinkedIn Post Inspector.
