How Erik Cagi Earns $12K+/Month with Spanish Course Ads

Case Study Overview

Affiliate marketer Erik Cagi discovered a high-margin opportunity in the language niche by promoting Synergy Spanish courses on YouTube. Rather than creating his own videos, heextracted tutorial contentfrom the affiliate sales page, re-uploaded it to his channel, and combined that with targeted Google Ads using a $500 coupon deal. Within weeks, Erik saw an average daily revenue of $830 per product, which scaled to over $12,000 net profit each month across five offers.

Niche Selection & Product Choice

Most affiliates target health, finance, or dating. Erik chose the Spanish-learning niche—an under-served market on ClickBank. He pickedSynergy Spanishfor its $50.25 average commission and its tutorial-style sales video. This combination of uniqueness and high perceived value laid the foundation for his campaign.

Extracting & Hosting Tutorial Videos

Instead of filming his own demo, Erik used the Wistia Video Downloader Chrome extension to pull the sales page video directly. Then he uploaded it to his YouTube channel under an optimized title: “An Easy Way to Get By in Spanish — And You Only Need 138 Words.” This instantly gave him a professional, tutorial-based creative that built trust with viewers.

YouTube SEO & Tag Generation

Next, Erik ran the title and description through RapidTags to generate SEO-effective tags like “how to learn Spanish fast” and “Spanish lessons.” He pruned irrelevant tags, ensuring each keyword directly connected to the Synergy Spanish offer. This organic SEO push drove free traffic and initial sales.

Leveraging Google Ads Coupons

Erik claimed a $500 Google Ads credit by spending $500, then created a Custom Video Campaign targeting non-Spanish regions with skippable in-feed ads. He set a €0.30 max CPV bid, used a Canva-made thumbnail, and geo-targeted markets like Spain, Mexico, and Argentina. This low-risk ad test generated instant sales within 24 hours.

Results & Scaling

The first product averaged $3,320 in monthly revenue after ads, netting $2,820 profit. By replicating this process across four more offers, Erik reached $16,600 revenue and $12,100 profit each month. The system is simple: find tutorial-style offers, extract the video, optimize on YouTube, and boost with ads.
