What Our Partners Say
Don’t just take our word for it. Here’s what advertisers and publishers say about working with L3K.
“L3K transformed our affiliate program completely. We went from 200 to 2,000 active publishers in just 6 months, and our CPA dropped by 35%. The quality of affiliates in their network is unmatched — every single one goes through a rigorous vetting process.”
Marcus Chen
VP Growth, FinanceLeads Pro
“The SmartTrack™ technology is a game-changer. We used to spend hours reconciling conversion data across platforms. Now everything is server-to-server accurate in real-time. Our team saves 20+ hours per week on reporting alone.”
Sarah Williams
Head of Performance, DirectResponse Media
“Weekly payouts, no excuses, no delays. In 10 years of affiliate marketing, L3K is the most reliable network I’ve ever worked with. My revenue grew 17x in the first year because their offer catalog is massive and the EPCs are consistently higher than competitors.”
Alessandro Rossi
Publisher, MediaTraffic EU
“Our CPA dropped 40% after switching to L3K, and the quality of leads improved dramatically. Their FraudShield™ technology caught fraudulent traffic that our previous network completely missed. We’ve since expanded to 5 new markets through their global network.”
Priya Sharma
CMO, SwiftLoans Digital
“Their account managers genuinely care about your success. My AM responds within minutes, provides strategic insights, and proactively suggests optimizations. It’s rare to find this level of partnership in the industry.”
James O’Brien
Affiliate Director, PeakConvert
“From application to first payout in 48 hours. That’s the L3K difference. We tested them with a small budget and within 3 months, they became our top-performing network generating $1.2M in annual revenue.”
Yuki Tanaka
CEO, AdFlow Networks
“L3K’s vertical expertise in iGaming and finance is second to none. They connected us with premium publishers we couldn’t reach on our own, and the compliance team ensures everything stays within regulations. True professionals.”
Elena Kovacs
Director of Partnerships, BetPro Group
“As a publisher running high-volume search arbitrage, I need a network with rock-solid tracking and high-EPC offers. L3K delivers on both. Their API integration was seamless, and the real-time reporting helps me optimize campaigns on the fly.”
David Okonkwo
Founder, ClickForge Digital
“We were skeptical about CPA networks after bad experiences with fraudulent traffic. L3K’s FraudShield™ changed our mind entirely. Less than 0.5% fraud rate vs. 15% with our previous network. The ROI speaks for itself.”

Frequently Asked Questions
Everything you need to know about L3K.
L3K is a premium performance marketing network that connects top-tier advertisers with vetted, high-quality publishers. We specialize in CPA (Cost Per Action) advertising, meaning advertisers only pay when a user completes a desired action — whether that’s a sale, lead, signup, or install. With proprietary tracking technology and a dedicated team, we help both sides of the marketplace maximize ROI.
Cost Per Action (CPA) advertising is a performance-based model where advertisers pay only when a specific action is completed. Unlike CPM or CPC models, you’re not paying for impressions or clicks — you’re paying for results. Advertisers set the payout for each conversion, publishers promote the offers to their audience, and L3K’s SmartTrack™ technology tracks every conversion in real-time with server-to-server accuracy.
We support 30+ verticals including finance, eCommerce, health & wellness, insurance, gaming, dating, education, SaaS, home services, travel, and more. Our diverse advertiser base means publishers always have access to high-converting offers in their niche, and advertisers can tap into traffic from publishers who specialize in their vertical.
Publishers receive weekly payouts via wire transfer, PayPal, Payoneer, or cryptocurrency. Our minimum payout threshold is $100. We pride ourselves on a 98% on-time payment rate — no net-60 terms, no excuses. Reliable payouts are a cornerstone of L3K’s reputation in the industry.
L3K uses our proprietary SmartTrack™ platform, which provides real-time tracking with server-to-server (S2S) postbacks, cookie-based tracking, and advanced fraud detection powered by AI. Features include multi-touch attribution, custom conversion funnels, granular reporting by sub-ID, geo, device, and more — all accessible from a single intuitive dashboard.
Getting started is simple. Sign up on our platform, submit your offer details (landing pages, payout structure, targeting criteria), and our team reviews your application within 24 hours. Once approved, your offers go live to our network of 2,000+ vetted publishers. You’ll receive a dedicated account manager to help optimize your campaigns from day one.
We accept traffic from search (SEO/SEM), social media (paid and organic), native advertising, email marketing (with compliance), push notifications, and display advertising. We strictly prohibit incentivized traffic, bot traffic, cookie stuffing, and any form of fraudulent activity. Our AI-powered fraud detection system monitors traffic quality 24/7.
L3K has offices in New York, London, and Singapore, with a fully remote team of 80+ professionals across 15 countries. Our global presence allows us to provide localized support and market-specific expertise to advertisers and publishers in 40+ countries worldwide.
