Rich previews

Why previews matter for safety

When you receive a short link in a message, you have almost no context. Attackers exploit this lack of context by using urgent wording and hiding the destination behind a shortener. Rich previews restore some of that missing context: the page title, description, and preview image often reveal whether a link matches what the sender claims.

TechLinkss reads the public HTML metadata and extracts Open Graph and standard meta tags. The result is a quick “identity check” for the destination. You can compare what the preview says with the message you received and decide whether it looks consistent.

What TechLinkss extracts

• Title: from Open Graph (og:title) or the HTML <title>.
• Description: from og:description or meta name="description".
• Image: from og:image when available.

This data is intentionally limited to what is publicly visible and useful for humans. We do not execute scripts, and we do not interact with the page beyond safe HTTP requests.

How previews can reveal deception

Common scams can be spotted by mismatch signals:

• The preview title mentions a different brand than the message.
• The description is generic, spammy, or unrelated to the claimed content.
• The image is missing or looks like a template used by many scam sites.
• The final domain is unfamiliar, newly registered, or a strange subdomain.

Even legitimate sites can have poor metadata, so this is not a binary “safe/unsafe” test. Think of it as an extra clue to reduce uncertainty.

SEO and quality considerations

Open Graph tags were created to improve link sharing on social platforms. Many professional websites maintain them carefully. That means a good preview is often a sign of a real site, while missing or broken metadata can be a warning—especially for pages that claim to represent well-known brands.

TechLinkss also cleans up common HTML entities so titles and descriptions render correctly. This matters because broken previews can hide important words, or make a page look suspicious when it is not.

FAQ

Why is the image sometimes missing?

Some pages do not publish Open Graph images, block bots, or require authentication. In that case TechLinkss shows a placeholder and still displays the rest of the metadata.

Can metadata be faked?

Yes. Attackers can set misleading titles and images. Always combine the preview with the domain and the redirect chain.

Does TechLinkss store cookies from the destination?

No. We do not keep tracking cookies and we do not run scripts. The scanner reads public HTML and headers only.
