Hey everyone


As affiliate marketers, we all know that having strong creatives can make or break a campaign. But how do you consistently create high-performing ad creatives without reinventing the wheel every time?


Most of us turn to spy tools for inspiration—those familiar platforms that show you what’s working for others. However, as someone who has worked extensively with both free and paid tools, I can confidently say: you might be overlooking one of the best free tools out there—Facebook Ads Library.


In this post, I’ll walk you through how I’ve used the Facebook Ads Library to find winning creatives, gain targeting insights, and even discover stealthy affiliate strategies—all without paying a dime.


Why Most Paid Spy Tools Don’t Deliver What You Expect​


Spy tools are helpful—but far from perfect. Many of them show only a fraction of what's actually being run on platforms like Facebook and Instagram. Worse, they often come with hefty monthly fees. Some popular ones cost $50–$80 per month or more, which is no small expense—especially for beginners trying to test multiple tools, landing page builders, cloakers, and trackers.


Another issue? No spy tool guarantees profitability. Just because a creative is running doesn’t mean it’s converting profitably.


Why Facebook Ads Library Is a Game-Changer​


Now, here’s the kicker: Facebook’s Ad Library offers access to a massive archive of ads currently or recently running on both Facebook and Instagram, completely free.


It was initially created to increase transparency in political advertising, but it now includes all types of ads, across any niche or industry. You don’t need to register, verify your identity, or pay anything to use it.


So why don’t more affiliates talk about it? Maybe because it’s too good—and no one wants to give away their edge.


What You Can Do With It​


Here’s what makes Facebook Ads Library especially powerful:


  • Search by product or keyword – Want to find ads promoting a specific supplement or skincare offer? Just type it in and you’ll see all related creatives.
  • See ads by domain – This is great for tracking affiliates running gray-hat offers. You can find ads pointing to Shopify, Google Sites, or Tilda domains.
  • Explore ads by app name – Searching for gambling, betting, or casino offers? Use keywords like “slots” or “casino” and you’ll uncover dozens of ads promoting Android apps.
  • See active status and launch date – Helps you identify what creatives have longevity and are currently scaling.
  • Targeting insights (EU only) – In European countries, you can even see age, gender, and demographic targeting info used by the advertiser.
  • View fan pages running the ads – A great way to reverse-engineer funnel strategies and track content direction.

Example: Finding Winning Creatives for a Weight Loss Offer​


Let’s say you're promoting a weight loss supplement in Poland.


You can simply search using the product’s name and filter for the specific country. By selecting only “Active” ads, you’ll get a clear snapshot of current running creatives—text, images, and videos. Clicking on “Ad Info” (when available in EU countries) shows targeting data, audience age breakdown, and even whether men or women responded better.


From here, you can easily spot angles that are working, whether it’s health claims, before/after images, or time-sensitive messages.


Bonus: Use It With Domains & Landing Page Builders​


Many affiliates use free page builders like Tilda, Google Sites, or even Shopify to host landers. You can plug in part of the domain and see ads that redirect to those pages. This lets you spot cloaked campaigns, funnel structures, and even affiliate networks being used.


Popular domain zones among affiliates include: .site, .top, .club, .work, .space, .online, and more.

Final Thoughts​


The Facebook Ads Library isn’t just a transparency tool—it’s a full-blown competitive research weapon that too many affiliates ignore. It’s free, packed with data, and surprisingly versatile if you know how to dig.


Sure, it has some limitations—like not offering convenient filters for GEOs or bulk downloads—but the insights you gain far outweigh the extra manual effort.


Whether you’re just getting started or running high-volume campaigns, this tool can save you time, money, and guesswork.
