Home Features Link masking

Keep your link in the address bar.

Link masking — also called link cloaking or URL masking — shows your short URL in the browser address bar the whole visit while the destination loads underneath. Branded, white-label on a custom domain, and safe for SEO.

Destination page

Spring launch is live

your URL stays put

What it is

Your short link stays visible.

A normal short link redirects: click it and the destination’s long URL takes over the address bar. Link masking keeps your short URL in the bar the entire visit while the destination loads in a full-viewport frame underneath. The visitor reads your brand, not someone else’s domain.

One toggle on any link.

Flip Keep my link in the address bar on a link and slsh.me serves the destination inside your own branded wrapper. No redirect away, no other name in the bar, no second tab.

It works on a slsh.me subdomain out of the box and becomes a full white-label on your custom domain.

  • Affiliate links that keep your domain in the bar, not the merchant’s.
  • Campaign links where the short URL is the brand on every channel.
  • Creator bio links that never flash a raw destination URL.

Branded — on a custom domain it is a full white-label
One toggle — turn it on per link, no setup thread

White-label

Pair it with your domain for the full brand experience.

Masking is good on a slsh.me link. It’s complete on yours. Point a custom domain at slsh.me and the address bar shows go.yourco.com/launch the whole visit — the destination’s domain never appears.

Add a branded social card and the three things a visitor sees all wear your domain: the short link they click, the preview that unfurls in the chat, and the page that loads. One coherent brand, end to end.

  • The link: go.yourco.com/launch
  • The preview: your title, description, and image
  • The page: loads masked, your URL stays in the bar

How it works

Three steps, and a pre-flight check.

Turn masking on per link. Before it goes live, slsh.me checks whether the destination allows being framed and warns you up front if it doesn’t — so you never publish a masked link that lands on a blank frame.

1

Paste your URL

Create a short link and paste the HTTPS destination you want to mask. Masked pages are https only — no mixed content.

2

Toggle the mask

Flip Keep my link in the address bar. We run a pre-flight check for X-Frame-Options / CSP and warn you if the site blocks framing.

3

Save

Save the link. Visitors now see your short URL the whole visit while the destination loads underneath. On a custom domain it’s a full white-label.

Is masking safe?

Transparent masking, not deceptive cloaking.

“Cloaking” has a bad name because Google penalizes deceptive cloaking — showing crawlers different content than users. And naive masking can create duplicate content or block indexing. slsh.me masking is the legitimate, transparent kind, built so neither problem can happen.

Built so it can’t hijack your SEO.

The masked frame is served noindex,nofollow with a canonical pointing at the destination — so there’s no duplicate-content footprint and nothing for search engines to index in place of the real page.

  • noindex frame + canonical to destination — no duplicate content, no index hijack.
  • HTTPS only — the masked page is always secure, no mixed content.
  • Pre-flight check — we warn you up front if a site blocks embedding.
  • Iframe-based, not a proxy — your own branded wrapper, not content rewriting, and not deceptive crawler cloaking.

Same content for everyone, real page stays canonical. That’s the whole difference between transparent masking and the cloaking Google penalizes.

noindex,nofollow — the frame is never indexed
canonical → destination — the real page keeps its ranking
HTTPS only — no mixed content, no proxy rewriting

Link masking vs redirect

Same click. Different address bar.

Both start with a short link. The difference is what the visitor sees in the address bar once the page loads.

Plain redirect

go.yourco.com/launch → longsite.com/...

  • The destination URL replaces your short link in the bar.
  • Fastest path to the page; nothing loads in a frame.
  • Best when you don’t mind the destination domain showing.

Link masking

go.yourco.com/launch stays in the bar

  • Your short URL stays in the bar the entire visit.
  • The destination loads in a full-viewport frame underneath.
  • Best when your branded link should stay visible the whole time.

Questions

The honest answers.

How do I turn on link masking?
Open any link, flip Keep my link in the address bar, and save. slsh.me runs a pre-flight check for X-Frame-Options / CSP and warns you up front if the destination can’t be framed — so you never publish a masked link that lands on a blank frame. On your own custom domain it becomes a full white-label.
Is link masking safe for SEO?
Yes — the transparent kind is. The masked frame is served noindex,nofollow with a canonical pointing at the destination, so there’s no duplicate-content or index-hijacking risk, and it’s not the deceptive crawler cloaking Google penalizes.
