Knowing what your competitors are doing in paid ads gives you a real edge.

You can see their creatives, angles, landing pages, and sometimes even estimated spend.

Done ethically and legally, competitor ad research helps you build better campaigns. Here's how to spy on competitors' ads the right way.

Why should you spy on competitor ads?

You get inspiration for creatives and messaging.

You understand which angles and offers are working in your niche and spot gaps (e.g. audiences or formats they're not using).

You can benchmark your own ad frequency and landing page quality. It's about learning, not copying verbatim.

What tools can you use for competitor ad research?

Official ad libraries

Meta Ad Library (Facebook & Instagram), Google Ads Transparency Center, and TikTok Ad Library let you search by advertiser name or keyword.

You can see active ads, sometimes with start date and platforms.

Third-party spy tools

Tools like AdEspresso, BigSpy, or similar aggregators give you more filters, creative history, and estimated spend.

Use a mix of official libraries and one or two spy tools for depth.

What strategies work when spying on competitor ads?

Practical approach:

  • Search for known competitor names and your main keywords in ad libraries.
  • Save winning-looking creatives (angles, hooks, formats) and reverse-engineer why they might work.
  • Check landing pages: look at structure, offer, and CTA—then improve on them for your brand.
  • Track new ads over time to see who's scaling and what's fresh.

What are the best insider tips?

Focus on ads that have been running for weeks or months; they're likely profitable.

Look at comment sentiment and engagement for social proof.

Combine competitor insights with your own tests—use their ideas as a starting point, then beat them with better creative and targeting.

Ethical spying means gathering inspiration and market intel, not stealing creative or trademarks.

With the right tools and a clear strategy, you can spy on competitors' ads effectively and use those insights to build better, more profitable campaigns.
