ZIK Analytics offers a powerful Competitor Research tool designed to help eBay sellers—whether dropshippers or inventory sellers—unlock key insights and grow their e-commerce businesses. This comprehensive guide breaks down how to use the tool effectively and outlines three powerful methods for identifying successful competitors and their best-selling products. We will break it down in the following article or you can simply watch the training video we have prepared:

🔍 Why Competitor Research Matters

Understanding your competitors gives you a crucial edge on eBay. Whether you're launching into a new niche or optimizing your current listings, the ZIK Competitor Research tool helps you:

  • Analyze niche demand and competition levels

  • Discover top-performing sellers who use the same suppliers or operate in your niche

  • Gain real-time insights into what’s actually selling

  • Continuously uncover new product opportunities

  • Improve your listings and outperform other sellers

By leveraging competitor data, you work smarter—not harder—and build a more profitable, data-driven store.

📚 Key Takeaways from the Training

The ZIK training covers the full cycle of smart competitor research, including:

  • Niche Analysis: Evaluate how competitive a niche is and whether there's enough demand to justify entering.

  • Seller Discovery: Identify high-performing sellers in your niche or those sourcing from the same suppliers.

  • Seller Metrics Analysis: View detailed data like:

    • Sell-through rate (sales vs active listings)

    • Successful listings

    • Feedback score

    • Average product price

    • Active listings and total sold items

    This data is shown by default for the past 30 days, but you can adjust the time range to the past 7, 14, or 21 days. ZIK tracks 95% of eBay sellers, meaning you're getting near real-time, trustworthy insights.

  • Product Discovery: Spot best-selling items even if ZIK’s algorithm doesn’t detect a direct supplier match—often these “unmatched” products turn out to be hidden gems.

  • Listing Optimization: Learn how to improve competitor titles and pricing to boost your own sales.

  • Product Tracking System: Set up a routine to monitor sellers regularly and find new winning products.

🧠 Three Powerful Methods to Find Good Sellers

1. Market Insights Dashboard

This is the easiest and most recommended method to start competitor research.

✅ How it works:

  • Set your marketplace (e.g., eBay.com), business model (e.g., dropshipping), and supplier website (e.g., Amazon US) in your ZIK seller settings.

  • The “Trending Dropshippers” column then updates every 24 hours, displaying sellers who match your setup.

  • A flaming icon next to a seller's name means they’re generating high sales relative to their listings—making them perfect candidates for analysis.

2. Spy Icon Across ZIK Analytics

The Spy icon is found across various ZIK tools and allows you to deeply analyze eBay sellers and their sold items.

Where to use it:

  • Trending eBay Products: View sellers aligned with your filters and criteria.

  • Product Research Tool:

    • Inventory sellers: Type the product name to find competitors selling the same item.

    • Dropshippers: Paste in the supplier’s product title (e.g., from Amazon), then apply filters to show only dropshippers who are selling that product.

  • Product Explorer:

    • Inventory sellers: Enter product names to find matching listings.

    • Dropshippers: Go to the “Other” filter section and select “Dropshippers Only”. Combine this with “Exact Match” and your chosen supplier site (e.g., Amazon) to reveal sellers using the same source.

3. Direct eBay Search + ZIK Research

Want to reverse-engineer a product you found on Amazon?

✅ Here’s how:

  1. Search the product title on eBay.

  2. Find a matching listing.

  3. Copy the seller’s ID from their eBay profile (under the “About” section).

  4. Paste the seller ID into ZIK’s Competitor Research tool for analysis.

If the item shows no supplier match, don’t stop there—use the product image in Google Photos or reverse image search to help track down the source manually.

📊 Analyzing Seller Performance and Metrics

Once you’ve selected a seller, ZIK gives you a full breakdown including:

  • Business Model: e.g., dropshipper using Amazon US

  • Sell-Through Rate: Sales vs active listings

  • Active Listings & Total Sales

  • Successful Listings

  • Feedback Score

  • Average Selling Price

  • Time Filter: Set to 7, 14, 21, or 30 days

  • Product Match Tool: Click the magnifying glass icon to find other sellers of the same item

This rich data helps you evaluate whether a seller’s strategy is worth modeling or competing against.

🏆 Discovering Best-Selling Products & Optimization Tips

Whether you're dropshipping or holding inventory, this tool lets you identify what’s working—and why.

🎯 Focus on:

  • Products with at least 2 sales in the past 7 days, or 6 sales in the past 30 days

  • Items that are exact matches or similar alternatives that could perform well

💡 Product Match Icons:

  • Exact Match: Green checkmark – same product as supplier.

  • 🔄 Similar Products: Close alternatives; great for creative sourcing.

  • Unmatched Products: No supplier found – often “hidden gems.” Use image or title to track these manually.

📁 Once saved, you can:

  • Export products as a CSV file for manual upload to your store

  • Use ZIK’s integration with AutoDS or other monitors for automated listing

  • Optimize product titles by:

    • Removing redundant or irrelevant words

    • Avoiding VeRO brands and restricted terms

  • Price products slightly lower than competitors, even by $0.30, to increase conversions

🏗️ Building Your Competitor Network

You can save sellers to your Watchlist, allowing you to:

  • Rescan them every two weeks to find new best-sellers

  • Add notes about each seller’s niche, title format, pricing strategy, or branding

  • Monitor changes in their product lineup or approach

This ongoing research helps you evolve your strategy, ensuring you never run out of product ideas or lose sight of market trends.
