Affiliate Link Cloaker

Cloak long affiliate URLs with branded short links. Generate redirect codes for Apache, nginx, and JavaScript. Free, offline, and secure.

What you can do with marketing tools

  • Replace long affiliate URLs like amazon.com/dp/B08XYZ?tag=yoursite-20&linkCode=ll1&ref=abcd... with a clean branded short link such as yoursite.com/go/item: Affiliate Link Cloaker.
  • Generate the matching redirect snippet for your server (Apache .htaccess, nginx rewrite, or JavaScript client-side redirect) so the short link actually works on day one.
  • Keep affiliate tracking parameters intact through the redirect so attribution, commissions, and conversion events still reach the network.

Reach for marketing tools when the job is preparing a link, a tracking snippet, or a campaign asset for publication. If the job is inspecting meta tags, schema, or sitemap output, the SEO tools are closer. For URL-encoding or decoding, percent-encoding, or inspecting query strings, the developer category has the low-level utilities.

The Marketing toolkit

Tool What it does When to use
Affiliate Link Cloaker Takes a long affiliate URL, a desired branded short path, and a redirect type. Generates the short URL plus server config for Apache, nginx, or JavaScript. Preserves all tracking query parameters through the redirect. Cleaning up a batch of Amazon Associates links before publishing a product roundup; generating redirect rules for a WordPress site where plugins feel like overkill; creating a set of branded short links that survive if the underlying affiliate program changes.

How to choose the right marketing tool

  • If the input is an affiliate URL and you want it cloaked for a branded domain, start with Affiliate Link Cloaker. Pick the redirect type that matches your hosting (Apache for most shared hosts, nginx for VPS and containers, JavaScript if you cannot edit server config).
  • If you need to add UTM parameters to a URL rather than hide them, wait for the UTM builder or paste the URL plus parameters into a text editor for now. A short URL alone is not a tracking URL.
  • If the goal is pretty URLs for internal site navigation rather than affiliate cloaking, your CMS probably has a native redirect module that is a better fit.

Frequently asked questions

Q: Is link cloaking allowed by affiliate networks?

Most major networks permit cloaking as long as tracking parameters pass through cleanly and the final destination matches the affiliate offer. The Affiliate Link Cloaker preserves every query parameter by default so commission tracking continues to work. Amazon Associates, ShareASale, and Impact all allow branded short links. Check specific program terms before a large campaign.

Q: What redirect type should I use?

Apache .htaccess works on almost every shared host (Hostinger, Bluehost, SiteGround). nginx rewrite blocks fit VPS, containers, and most modern hosting stacks. JavaScript redirects run client-side with no server config at all, useful on static sites or when server access is limited. For SEO value, 301 server redirects beat JavaScript redirects because search engines pass authority through them.

Q: Will cloaked links still pass affiliate tracking and commission attribution?

Yes. The generated redirect uses a 301 or 302 and keeps the full query string intact, so the affiliate cookie is still dropped at the destination. If the network uses a pixel or postback instead of a cookie, the same passthrough works because the final URL is unchanged from the user's perspective.

Q: Are my URLs stored or shared?

No. Affiliate Link Cloaker generates everything in the browser. The long URL, the short path, and the redirect snippet never touch a server.
