Click redirection

What is Click redirection?

Click redirection is a mobile ad fraud technique in which a script automatically redirects users who click on an ad to a different website or landing page without their knowledge or consent. The technique artificially inflates click metrics, making ad campaigns appear more successful than they actually are. Fraudulent publishers exploit this mechanism to generate unearned revenue from advertisers paying on a cost-per-click or cost-per-action basis.

How it works

Click redirection operates through injected scripts or code embedded either in a publisher's webpage or within the ad unit itself. When a user clicks on a link or advertisement, the script triggers immediately and silently routes the user to a third-party destination instead of the intended landing page.

Common Redirect Techniques

Fraudsters use several technical methods to execute click redirection. HTTP redirects instruct the browser to follow a new URL before the user sees any content. HTML meta refresh tags embed a timed redirect instruction directly in the page markup, causing the browser to navigate away after a set interval. JavaScript-based redirects execute dynamically in the browser, often obscuring the redirect chain and making detection harder.

How the Fraud Propagates

In many cases, the redirect chain passes through one or more intermediary URLs before reaching a final destination. Each hop in the chain can register a trackable event, generating artificial impressions or clicks that feed inflated data back to ad servers and measurement systems. The user lands on a page unrelated to the ad they intended to click, and the advertiser is charged for a click that delivered no genuine user intent.

Detection Signals

Mobile measurement partners (MMPs) identify click redirection through several behavioral signals. Abnormally short click-to-install times suggest clicks are being generated without real user engagement. Unusual click volume spikes from specific publishers, IP address clusters, or device types indicate automated redirect activity. Mismatches between click metadata and downstream install or conversion behavior further flag suspicious traffic for review.

Why it matters

Click redirection directly harms advertisers by inflating cost-per-click and cost-per-action charges for traffic that carries no genuine user intent. Budgets are consumed by fraudulent interactions rather than real prospects, which reduces the effective return on ad spend and distorts campaign performance data. When inflated click counts feed into attribution models, optimization algorithms make decisions based on corrupted signals, compounding the damage over time.

Beyond financial losses, click redirection erodes trust in the publisher ecosystem. Advertisers who detect fraudulent traffic must audit their media partners, often pausing or terminating relationships with networks that fail to maintain clean inventory. For legitimate publishers, the presence of redirect fraud in a network devalues genuine placements and suppresses fair market rates.

Using an MMP like Airbridge enables advertisers to flag and filter redirect-driven clicks before they influence attribution decisions, protecting both budget and data quality.

How to protect against click redirection fraud

Start by partnering with a mobile measurement partner that provides fraud protection and click validation capabilities. An MMP monitors click signals in real time, comparing metadata such as click origin, IP address, device fingerprint, and click-to-install time against expected behavioral patterns to identify redirect anomalies.

Apply a blocklist to known fraudulent publishers, IP ranges, and ad networks with a documented history of redirect activity. Regularly audit your media mix and review publisher-level reporting to identify traffic sources with disproportionately high click volumes but low conversion or engagement rates.

Set click-to-install time thresholds as part of your fraud filtering rules. Clicks that convert to installs within an implausibly short window are strong indicators of automated redirect fraud rather than genuine user intent.

Work exclusively with reputable ad networks that enforce app-ads.txt and supply-side transparency standards. Requiring partners to adhere to supply chain verification reduces the risk of redirect-prone inventory entering your campaigns.

Monitor your campaigns continuously rather than reviewing performance at fixed intervals. Redirect fraud campaigns often spike quickly before detection and then shift to new traffic sources. Real-time alerting through your MMP allows you to pause affected placements before significant budget is wasted.
