Link Ninja (LTK)
LTK's browser bookmarklet that turns any product page into an affiliate link with one click.
Link Ninja is a browser bookmarklet from LTK (formerly RewardStyle) that lets you generate affiliate links without leaving the retailer’s website. Instead of logging into your LTK dashboard, searching for a product, and copying a tracking link, you browse the store like a normal shopper, click the Link Ninja button in your bookmarks bar, and get a commission-trackable link immediately.
If you’re an LTK creator who links to products regularly, this is the single biggest time-saver on the platform.
What it does
You’re browsing Nordstrom. You find a jacket you want to recommend. You click the Link Ninja bookmark. A small overlay pops up with your affiliate link for that exact page, ready to copy and use wherever you want: blog post, email, Instagram story, LTK shop.
That’s it. No switching tabs, no product searching, no dashboard navigation. The link is tracked to your LTK account and earns commission the same way any other LTK link would.
Link Ninja also shows the brand’s commission tier (High, Medium, or Low) when you generate a link, so you know what you’re earning before you promote something.
How to install it on desktop
Step 1: Find Link Ninja in your LTK account
Log into your LTK Creator account on desktop. In the top menu, go to Apps, then scroll to Link Ninja. You’ll see a small black-and-white button with a karate figure icon.
Step 2: Drag it to your bookmarks bar
Click and hold the Link Ninja button, then drag it up to your browser’s bookmarks bar and release.
If you can’t see your bookmarks bar:
- Chrome: Click the three dots in the top right, go to Bookmarks and Lists, and check Show Bookmarks Bar. Or press
Ctrl+Shift+B(Windows) /Cmd+Shift+B(Mac). - Firefox: Click the menu button, go to Bookmarks, and check Show Bookmarks Toolbar.
- Safari: Go to View in the menu bar and click Show Favorites Bar.
Step 3: Start linking
Navigate to any partnered retailer’s website. Click the Link Ninja bookmark. If the retailer is in LTK’s network, you’ll get an affiliate link. If they’re not, Link Ninja will let you know.
How to use it on mobile
On mobile, Link Ninja lives inside the LTK Creator App. Open the app, tap the Link Ninja icon (the karate figure), and search for a brand or store. You can then browse and generate links from within the app.
The mobile version is functional but less seamless than desktop. On desktop, you’re already on the retailer’s site looking at the exact product. On mobile, you’re working from within the LTK app’s interface.
Tips for using Link Ninja
Rename your bookmark. The default bookmark name is long. Rename it to something compact like “LN” or “LTK” so it takes up less space in your bookmarks bar. Right-click the bookmark, select “Edit,” and change the name.
Keep it visible. Don’t bury Link Ninja in a bookmark folder. Pin it to your bookmarks bar where you can reach it with one click. Fast access is what makes it useful.
Link to large retailers when possible. Products sold at Nordstrom, Sephora, Target, and other major retailers tend to convert better than the same product on a small brand’s own website. Shoppers trust big retailers, and they’re more likely to add items to their cart once they’re browsing.
Check commission tiers before promoting. Link Ninja shows whether a brand’s commission is High, Medium, or Low. If you’re choosing between two similar products to feature, the commission tier can be a tiebreaker.
If it stops working, reinstall it. Bookmarklets occasionally break when browsers update or when LTK updates their code. If Link Ninja stops generating links, delete the bookmark and repeat the installation process. Takes 30 seconds.
Not every retailer is supported. If you click Link Ninja on a site that isn’t in LTK’s network, you won’t get a link. You can request that LTK add the retailer, and if enough creators ask, they sometimes do. But smaller independent brands are less likely to be available.
Link Ninja vs. the LTK dashboard
You can create affiliate links directly from the LTK dashboard by searching for products and brands. Link Ninja doesn’t replace that. It’s an alternative for a different workflow.
| Link Ninja | LTK Dashboard | |
|---|---|---|
| Speed | Fastest (one click from any product page) | Slower (search, browse, select, copy) |
| Best for | Linking to specific products you find while browsing | Browsing product catalogs, finding inspiration |
| Works on | Any partnered retailer’s website | LTK’s interface |
| Shows commission rate | Yes (High/Medium/Low) | Yes (exact percentage in some views) |
| Requires | Desktop browser with bookmarks bar | Any browser or mobile app |
If you’re the kind of creator who discovers products by browsing stores and wants to link them in the moment, Link Ninja is essential. If you prefer curating from within LTK’s catalog, the dashboard works fine.
Frequently asked questions
Do I need an LTK account to use Link Ninja? Yes. Link Ninja is exclusively for approved LTK creators. It generates links tied to your creator account.
Does Link Ninja work on all websites? No. It only works on websites of brands and retailers that are partnered with LTK. If a retailer isn’t in the network, Link Ninja won’t generate a link. Most major retailers (Nordstrom, Sephora, Target, Amazon, Ulta) are supported, but smaller independent brands may not be.
Can I choose the link format? Yes. In your LTK profile settings, you can choose between different link formats (such as “rstyle” or “bitly” style). All links created with Link Ninja follow whatever format you’ve selected.
Does it work in Safari, Firefox, and Edge? Bookmarklets work in most major browsers. Chrome and Safari are the most reliable. If you’re having trouble in a specific browser, try reinstalling or switching browsers.
Is Link Ninja the same as the LTK Chrome extension? They serve a similar purpose, but Link Ninja is specifically a bookmarklet (a saved JavaScript bookmark), not a traditional browser extension. LTK has experimented with different tools over the years, and Link Ninja remains the primary desktop linking tool.
