INTRODUCTION​


After years in Forex and binary options, I hit a point where returns were shrinking fast. Regulations were getting tighter, competition was fiercer, and margins weren’t what they used to be. It was time to pivot.


I decided to explore microloan offers—low-ticket but high-demand financial services. I’ve always preferred GEOs in Latin America and Europe over expensive tier-1 markets, so when I spotted a promising CPA offer targeting Mexico, I knew I had to test it. And just to make things more interesting, I combined it with one of the most talked-about ad formats in the affiliate space right now: Push Notifications.


The result? A tidy profit of $891 on a $621 ad spend. Here’s how it happened.


CAMPAIGN BASICS​


Campaign Period: July 12 – August 31
Offer Type: Responsive Microloan – Mexico
Ad Format: Push Notifications
GEO: Mexico
Traffic Source: Push ads (mobile + desktop)
Spend: $621
Revenue: $1,512.05
Net Profit: $891.05


WHY PUSH NOTIFICATIONS?​


Push has been on my radar for months, and after meeting some folks at a recent conference who swore by its performance in the finance vertical, I was convinced to test it. The direct delivery to a user’s device, coupled with native-looking creatives, seemed like a perfect match for a financial service offer.


TARGET AUDIENCE & CREATIVES​


From my Forex days, I knew the sweet spot for this type of offer:


  • Students
  • Families living paycheck-to-paycheck
  • People in need of quick, short-term financial help

That insight shaped my creative direction. No flashy images. No irrelevant clickbait. I went with simple visuals of money and bright, clean backgrounds—just enough to grab attention without overpromising.


Ad Copy Example:


  • Title: ¿Necesita efectivo hoy? (Need cash today?)
  • Description: Solicite ahora y obtenga hasta $3000 (Apply now and get up to $3000)

All copy was in Spanish, professionally localized by a native Mexican freelancer I found for $4. Worth every penny—native language always wins trust.


CAMPAIGN STRUCTURE​


I started with two campaigns:


  1. Android mobile users – Push only
  2. Windows desktop users – Push + Banner creative

Both campaigns had:


  • CPC bidding
  • Frequency cap: 1/24
  • Activity targeting: “High”
  • Initial daily budget: $15
  • Total cap per campaign: $150

RESULTS & OPTIMIZATION​


Early results: Desktop push with banners had double the CTR of mobile-only push. However, mobile still brought larger traffic volume, which meant more conversion opportunities.


Encouraged, I tested a third campaign—Android push targeted at the “Low” activity group. The logic? Lower CPC and untapped traffic could yield better ROI even if CTR dipped.


What happened surprised me:


  • CTR for “Low” activity audience was 5x higher than the “High” activity group
  • Conversion rates stayed about the same
  • ROI jumped due to the cheaper clicks

The “unexpected” low-activity campaign ended up being the most profitable of the three.


FINAL STATS​


  • Total Clicks: 122,658
  • Total Spend: $621
  • Conversions: 810
  • Revenue: $1,512.05
  • Net Profit: $891.05
  • ROI: 69%

KEY TAKEAWAYS​


  1. Don’t underestimate “Low” activity audiences—sometimes they’re gold.
  2. Test everything, even settings you think might underperform.
  3. Native language creatives are a must for trust and conversions.
  4. Simple, relevant visuals beat over-the-top clickbait in finance offers.
  5. Desktop traffic can have higher CTR, but mobile often wins on sheer volume.

Next steps for me? Testing more ad creatives, experimenting with bid adjustments, and exploring other verticals like e-commerce and nutraceuticals. And yes—push notifications with banners are staying in my toolkit.
