Deep links send readers straight to the product, plan or category you recommend instead of a homepage. Here's how they work, when programs restrict them, and how to set them up without breaking tracking.

A deep link in affiliate marketing is a tracking link that sends the reader to a specific page — a product, a category, a pricing plan — instead of the merchant's homepage. It sounds like a small detail, but it is where a lot of affiliate revenue is quietly won or lost: every extra click between your recommendation and the checkout is a chance for the reader to wander off.
This explainer is for publishers, bloggers and creators who use network links today and want to understand how deep linking works under the hood, when it is allowed, and how to set it up without breaking tracking.
A deep link skips the homepage detour and lands the reader where your recommendation pointed.
What deep linking means
When you join a program, the network usually gives you a default tracking link. Click it and you land on the brand's homepage with your affiliate ID attached. A deep link carries the same tracking but points at a page you choose.
Two related terms get mixed up:
Affiliate deep link — a web tracking link with a custom destination URL. This is what this article covers.
Mobile app deep link — a link that opens a specific screen inside an installed app (via iOS Universal Links or Android App Links). Some programs support app deep links too, which matters for retail and travel brands with heavy app traffic.
If you are new to the tracking side, start with how affiliate tracking works — deep linking sits on top of the same click-and-cookie mechanism.
How a deep link works
A deep link is usually just the network's tracking URL with an extra parameter holding your destination, URL-encoded so it survives the redirect. A simplified example:
When the reader clicks, four things happen in a fraction of a second:
The tracking hop is identical to a homepage link; only the final destination changes.
01Click — the reader taps your link in an article, video description or email.
02Tracking hop — the network's server logs the click, your publisher ID and any sub IDs.
03Attribution set — the network sets its cookie or stores a click ID that the merchant will pass back on purchase (see pixel vs postback tracking).
04Redirect — the server decodes the destination parameter and sends the reader to that exact page.
Because the tracking hop is the same, commission rules don't change. The cookie window, attribution model and rate are identical whether the reader lands on the homepage or a product page. What changes is the reader's path.
Why product-page links beat homepage redirects
A homepage forces the reader to search for the thing you just recommended. Some will, many won't, and a few will find a different product with a different commission rate — or leave for a marketplace.

The trade-off is maintenance. A homepage link never 404s; a product link can die when stock or URLs change. That is a manageable cost, not a reason to avoid deep links.
Ways to create deep links
Most networks give you at least one of these:
Deep link generator in the dashboard — paste a merchant URL, get a tracking link back. This is the safest route because the network handles encoding.
Manual parameter — append your own encoded destination to the tracking URL, following the network's documented format.
Browser extension or bookmarklet — builds a tracking link from whatever merchant page you are viewing.
Automated linking tools — services like Skimlinks and Sovrn //Commerce rewrite ordinary outbound links into tracked deep links at click time, across thousands of merchants.
API or product feeds — for larger sites that build product pages or price widgets programmatically.
Whichever method you use, add sub IDs so you can tell which article, placement or platform drove the sale. Our sub ID guide covers a naming scheme that works across networks.
Where to start
The major networks below all support custom-destination links, and the automated tools handle deep linking for you across many merchants. Check each program's terms, since individual brands can still restrict it.
The mechanism is the same everywhere, but each channel has its own quirks:
Channel
Where the deep link goes
What to watch
Blog posts and reviews
Inline text links, buttons, comparison tables
Keep product links fresh on evergreen pages
YouTube and podcasts
Description or show notes
Use a short, readable redirect on your own domain that forwards the full tracking link
Instagram and TikTok
Link-in-bio pages, stories, shop tools
Some platforms wrap links in their own redirect, so test the full path on mobile
Email newsletters
Product blocks and CTAs
Email click tracking adds another hop; confirm parameters survive it
Mobile app traffic
App deep links, where the program supports them
Without app support, the link may open the mobile site instead of the app
For creators on social platforms, a clean link-in-bio page with one deep link per featured product usually beats a single homepage link for every post.
Is deep linking always allowed?
Usually, but not always. A program can:
Disable deep linking entirely, forcing all traffic through approved landing pages.
Restrict destinations — for example, banning links to sale pages, gift card pages or specific categories that carry no commission.
Exclude products from commission even when the link tracks, such as gift cards or some electronics.
Require approved domains when a brand runs several country sites.
Read the program terms or ask your affiliate manager before building a big content cluster around deep links into one merchant.
Common deep linking mistakes
Not URL-encoding the destination. An unencoded ? or & in the destination can be read as part of the tracking URL, breaking the redirect or dropping your ID.
Pasting tracking links inside other trackers. Chaining a network link through a link shortener or a second redirect can strip parameters. Test the final click path.
Linking to pages that carry no commission. Excluded categories still track the click but pay nothing.
Letting product links rot. Seasonal products disappear; a dead page loses the reader and the sale.
Forgetting sub IDs. Without them, you know a post earned money but not which link did.
Copying links from the browser bar. A plain merchant URL earns nothing; always run it through the generator or your auto-linker.

Step-by-step: set up and test a deep link
01Choose the exact page your recommendation refers to — the product, plan or category the reader expects.
02Check the program terms to confirm deep linking is allowed and the page earns commission.
03Generate the link in your network's deep link tool, or apply the documented parameter format with an encoded destination.
04Add sub IDs for the post, placement and platform.
05Test it in a private browser window: click, confirm you land on the right page, and check the click appears in your network dashboard.
06Track performance by sub ID and compare against any homepage links you still run.
07Audit monthly for broken or redirected destinations, especially on evergreen posts.
Affground's verdict
Deep linking doesn't change what a program pays per sale; it changes how many sales you actually get. Link to the page the reader wants, encode the destination properly, tag it with sub IDs and test the click path. Homepage links have their place, but for reviews, comparisons and tutorials, the deep link should be your default.
Frequently asked questions
What is a deep link in affiliate marketing?
It is an affiliate tracking link that sends the reader to a specific page, such as a product, category or pricing plan, rather than the merchant's homepage, while still crediting the sale to you.
Does deep linking change my commission rate?
No. The tracking hop, cookie window and commission terms are the same as the program's default link. Deep linking changes where the reader lands, which usually improves the chance they buy.
How do I create an affiliate deep link?
Use your network's deep link generator, apply the documented destination parameter with a URL-encoded target, use a browser extension, or let an automated linking tool convert ordinary links for you.
Why do I need to URL-encode the destination?
Characters like ? and & in the destination can be read as part of the tracking URL. Encoding them keeps the destination intact so the redirect works and your publisher ID isn't dropped.
Can a merchant block deep linking?
Yes. Some programs disable deep linking, restrict certain destinations such as sale or gift card pages, or exclude products from commission. Check the program terms before building content around it.
What's the difference between affiliate deep links and app deep links?
An affiliate deep link points a web tracking link at a specific page. An app deep link opens a specific screen inside an installed mobile app, which only works when the program supports app tracking.
How do I test a deep link?
Click it in a private browser window, confirm you land on the intended page, and check that the click shows in your network dashboard with the right sub IDs.
Do deep links break?
They can when a product is discontinued or a page URL changes. Audit evergreen posts regularly and update links to moved or removed pages.
