What Can a Link-Checking Tool Like What's the link? Help You Find Out?

Updated

A link-checking tool like What's the link? (whatslink.info) is typically used to inspect a URL before you open it or share it, so you can see where it actually points and what kind of content sits behind it. The useful takeaway is practical: it helps you make a quick judgment about a link's destination, not a full security audit. The available site information for whatslink.info is minimal, so the specifics below describe what this category of tool generally does and how to use one sensibly.

Common situations where a link checker helps

  • You receive a shortened link (bit.ly, t.co, and similar) in a message, email, or comment and want to see the full destination before clicking.
  • You are about to share a link with others and want to confirm it resolves to the page you intend.
  • You want a quick read on whether a link points to a file, a video, a social post, or a regular web page.
  • You are checking a link that looks slightly off — a misspelled domain or an unfamiliar subdomain — and want to see where it really goes.

What information you can usually get

What you want to know What the tool typically shows What to keep in mind
Final destination The expanded URL after redirects Redirect chains can pass through several hops; check the last one
Redirect path Intermediate URLs Some tools show only the final URL, not every hop
Content type Whether the target looks like a page, image, video, or file Detection is often based on headers and can be wrong
Page title or preview A title, description, or thumbnail Preview data comes from the destination and can be misleading
Basic safety signals Warnings about suspicious patterns Not a substitute for a real security scan

Who benefits most

  • Everyday users who want a second look before clicking a link from an unknown sender.
  • Community moderators and support staff who need to check links posted by others.
  • People sharing links who want to confirm a shortened URL still points where they expect.

If you need deep malware analysis, reputation scoring across threat databases, or legal takedown evidence, a dedicated security or threat-intelligence service is the better fit.

How to use one, step by step

  1. Copy the full link — including any query string — rather than retyping it.
  2. Paste it into the tool's input field and submit.
  3. Read the result in this order: final destination first, then the redirect path, then any content-type or preview information.
  4. Compare the final domain with the domain you expected. A mismatch is the main red flag.
  5. Verify before acting. If the destination looks unfamiliar, open it in an isolated browser session or check the domain through a separate reputation source.

Expected result: you should end up with the expanded final URL and enough context to decide whether to open, share, or discard the link.

Common pitfalls

  • Shortened links can be re-pointed. A short URL that was safe last week can redirect somewhere else today, so check at the moment you plan to click.
  • A clean result is not a guarantee. A tool that resolves redirects does not necessarily scan the destination for malware or phishing.
  • Preview data can be spoofed. Titles and thumbnails are supplied by the destination page.
  • Privacy matters. Avoid pasting links that contain personal tokens, session IDs, or private document keys into any third-party tool.
  • Login walls and region blocks can make a destination look different to the checker than it will to you.

Bottom line

Use What's the link? and similar tools to answer one question quickly: where does this link actually go? They are good for expanding shortened URLs, spotting domain mismatches, and previewing content type. Treat the result as a first filter, and pair it with your own judgment — or a dedicated security tool — when the stakes are higher.
