In the cross-border e-commerce and independent site advertising space, there's a well-known industry saying:"Copying winning products beats three months of trial and error."

When you see a competitor's ad still running with increased budget after several months on Meta (Facebook/Instagram), TikTok, or YouTube, it means the independent site behind it has validated the product's profit model and creative conversion rate. The "radar" used to discover these hidden winning products is what the industry commonly callsAd Spy Tools.

Among the many ad spy tools,AdSpy and BigSpy are the two most discussed and frequently used representatives. However, facing AdSpy's high barrier of $149/month, and the huge differences between the two tools in platform coverage, filtering dimensions, and creative granularity, many operators face a dilemma:

  • Which one captures more comprehensive and timely ad data, AdSpy or BigSpy?
  • For TikTok winning product selection, which should I choose? For Facebook independent sites in Europe and America, which should I choose?
  • Are ad spy tools suitable for long-term monthly subscriptions, or should they be used on-demand through group-buying platforms?

This article will deeply dissect the fundamental differences between these two tools and walk you through a complete"Intercepting high-converting winning ad creatives in 5 minutes".

Step 1: Lock in High-Value Target Markets and E-commerce Types

  • Country: Check United States,United Kingdom,Canada,Australia;
  • Site Type / Platform: Select Shopify or contains keywords myshopify.com. This action directly filters out invalid ads like games and dating, keeping only e-commerce product pages.

Step 2: Set Hardcore Engagement Thresholds (Eliminate New Ads Just Starting Out)

  • Likes: Minimum input 1000;
  • Shares: Minimum input 150.

Practical Tips: Likes can be bought, but high share rate indicates the product naturally possesses social currency and viral potential.

Step 3: Verify Ad Lifecycle (The Most Critical Metric)

  • Observe the ad's Created Date and Last Seen;
  • Judgment Experience: If an ad has been running continuously for 15+ days and is still in Active status today, it usually means the ad is generating consistent profit for the sellerโ€”because no cross-border seller would keep burning ad budget for two weeks on a severely losing creative.

Step 4: Trace Back to the Landing Page

  • Click the Landing Page link in the bottom right corner of the ad to directly open the competitor's Shopify store;
  • Observe their pricing strategy (whether they offer Bundle discounts), buyer review layout in the first 3 screens, and whether there are floating countdown timers and free shipping prompts to directly extract their high-converting visual elements.

III. Best Practices for Shared/Group Use of Ad Spy Tools

Ad spy tool queries and video downloads consume significant bandwidth. When using on group-buy platforms, follow these tips:

  1. Batch Processing with Focused Effort:
  • We recommend setting a fixed product selection day each week (e.g., Tuesday afternoons) to use the tool intensively for 2-3 hours, organizing filtered high-quality video material links and landing page URLs into local Feishu/Notion spreadsheets;
  1. Video Download Tips:
  • Avoid high-frequency concurrent batch downloads directly within the tool, which can trigger anti-scraping blocks; instead, copy video links and use browser right-click or local parsing tools for a smoother experience;
  1. Environment Isolation Protection:
  • Use RelayX's independent browser sandbox environment to avoid public Cookie conflicts and ensure saved search conditions aren't affected by other users' operations. More technical details available in RelayX Comprehensive Solution.

Frequently Asked Questions (FAQ)

Q1: Why do some ads show very high sales, but I lose money when I copy them?

Ad spy tools display audience engagement heat, but bestsellers depend not only on creatives but also on the competitor's ad bidding strategy, supply chain procurement costs, and private domain repurchase. Avoid blind copying; instead, learn the competitor's "pain point hook script" and make micro-innovations in product features or bonus bundles.

Q2: Will using AdSpy / BigSpy get my Facebook personal ad account banned?

There is no technical connection. Ad spy tools only scrape publicly displayed feed ads from big data endpoints, requiring no binding to your personal Facebook Business Manager (BM) or ad accountsโ€”the operation is completely independent third-party public data retrieval.

Q3: With limited budget in the first week, should I choose AdSpy or BigSpy?

If you focus on independent stores with Facebook in Europe/US as your main channel, AdSpy is recommended; if your core focus is TikTok product selection or short video commerce, BigSpy with more comprehensive multi-platform support is the smoother choice.
