How to Bypass adf.ly & adfoc.us Instantly

Published July 5, 2026 · 5 min read · LINKCUT

adf.ly is the original monetized URL shortener, launched in 2009. adfoc.us is a near-clone that copied its ad flow almost line-for-line. Both use a 5-second countdown, a "Skip Ad" button in the top right, and an interstitial ad banner. Because their DOM structure is 95% identical, any bypass tool that handles one handles the other.

The Shared Ad Engine

Both sites work the same way: request the shortened URL, get a countdown page, wait 5 seconds, then fetch the "final" URL from a signed endpoint (/go.php?u=... on adf.ly, /serve/?h=... on adfoc.us). The signing key is embedded in the page JavaScript and rotates every few hours.

What Broke and What Still Works

In 2024, both services added a browser fingerprint check that rejects bypass attempts from headless browsers with the default User-Agent. LINKCUT rotates realistic Chrome UAs and passes an audio-fingerprint header that mirrors real Chrome behavior, so the check passes.

Using LINKCUT to Bypass

1. Copy the adf.ly or adfoc.us link.
2. Open LINKCUT bypass tool.
3. Paste and click Bypass — 3–4 seconds later, the destination URL appears.

Why Not Just Use "Skip Ad"?

The Skip Ad button is real, but it counts as an ad impression, which is why publishers still get paid even when you skip. If you want to skip without incrementing the publisher's ad view (or without exposing your browser to the ad iframe), a server-side bypass is the only clean option.

Frequently Asked Questions

Is adf.ly the same as adfoc.us?

Different companies, same ad engine architecture. Bypass method is identical.

Do bypass tools support the old adf.ly custom domains?

Yes — q.gs, ay.gy, j.gs and other adf.ly aliases route through the same backend and are supported by LINKCUT.

Why does the destination URL sometimes redirect again?

Some publishers chain adf.ly through ouo.io to double their ad revenue. LINKCUT resolves the full chain in one bypass call.

Are adf.ly ads dangerous?

The countdown ads themselves are usually safe display banners. The real risk is the "Continue" button occasionally leading to malicious redirects. Server-side bypass sidesteps that entirely.

Can I bypass adfoc.us in bulk?

Yes, LINKCUT accepts bulk URL lists.
