How bonus tracking works (and why offers fail to register)

A frustratingly common story: someone reads about a welcome offer, signs up, deposits — and the bonus never lands. Support says the account wasn't eligible. Usually nothing was rigged. The attribution simply broke: the operator's system never registered which offer or referrer the signup belonged to. Understanding the mechanism takes five minutes and saves a lot of annoyance, whichever site's link you use.

Three moving parts: • The tracking link. The URL you click carries parameters identifying the referrer and, often, the specific campaign or offer. • The cookie. On arrival, the operator stores a small marker in your browser recording where you came from, valid for a set window (commonly 30 days, sometimes much shorter). • The attribution. When you complete registration, the operator reads that marker and assigns the account to the campaign — which is also what makes you eligible for the offer attached to it. Some operators also use a bonus code typed at registration instead of, or on top of, the cookie. If a code is shown with an offer, it usually is the attribution.

• Ad blockers and privacy extensions. Many block tracking parameters outright, so you land on the site with no attribution at all. This is the single most common cause. • Cookie clearing or strict privacy modes. Clearing cookies, or a browser that purges third-party storage aggressively, wipes the marker. • A long gap. Clicking today and registering three weeks later can fall outside the cookie window. • Switching device or browser. Clicking on your phone and registering on your laptop generally loses attribution — the cookie lives on the first device. • Private/incognito windows. Closing the window discards the session and its cookies. • Registering through a different route. Landing via the link but then navigating away, or opening the operator's app instead, can drop the reference. • Skipping the bonus code. Where a code is required, no code usually means no offer, however you arrived.

A short checklist that avoids nearly every failure case: 1. Pause ad-blocking on the operator's site before clicking through. 2. Click the offer link, then register in the same session — don't leave it for next week. 3. Stay on the same device and browser from click to signup. 4. Don't clear cookies between clicking and registering. 5. Enter the bonus code if one is shown with the offer. 6. Read the terms before depositing — minimum deposit, eligible payment methods and time limits all affect eligibility. Some offers exclude certain deposit methods, which catches out crypto users in particular. 7. Check the bonus is showing in your account before you deposit, where the operator displays it.

Start with the operator's support — they own the account and are the only ones who can apply a bonus. Have ready: the date and rough time you registered, the offer you expected, and any code you used. If that stalls and you signed up through our link, tell us. We have a partner contact at the operators we list and we'll raise your case with them directly, which is usually faster than a generic support queue. Be realistic about the outcome, though. Getting your case in front of the right person is not the same as overturning a decision: if a term genuinely wasn't met, the answer may still be no. We can escalate, not overrule. And before you chase a bonus at all, it's worth checking whether it's worth chasing: our bonus wagering calculator shows the turnover a given offer really demands.
