Server-Side vs JavaScript Cloaking: Which Is Safer?

There are two ways to make the white-page-or-offer decision: in the browser with JavaScript, or on the server before any HTML is sent. They are not equally safe. JavaScript cloaking runs after the page has already loaded. The browser downloads the page, then a script decides whether to redirect. The problem: the money content is technically delivered to the device, the logic is visible in the page source, and non-JavaScript bots (which many crawlers are) never run the script — so they can see whatever loaded first. It's convenient, but weak. Server-side cloaking makes the decision before a single byte of the offer is sent. The server checks the visitor, then renders either the safe page or the offer. A reviewer or bot never receives the money content at all, there's nothing to inspect in the page source, and there's no client-side logic to bypass. Cloackit's primary method is server-side: the generated PHP (or your connected domain) calls the decision engine and serves the result directly. That's the method we recommend for anything that matters. The lightweight JavaScript snippet exists only for quick, low-stakes embeds — it's the convenient option, not the strong one. Rule of thumb: if protecting the offer from reviewers matters, decide on the server.
