Why Use Terapeak

Terapeak provides real-time data on all eBay listings and helps you identify top-performing products that you can sell yourself.

It allows you to perform data analysis and visualization in a single place by streamlining market research.

For example, you can find products to sell on eBay by researching listing details such as price, images, and data-driven keywords.

And if you want to expand to global marketplaces, you can use Terapeak to research what’s selling on eBay in other countries.

Is Terapeak Free?

Is Terapeak Free

Effective April 15, 2021, Terapeak Product Research is 100% free for eBay sellers. However, Terapeak Sourcing Insights requires a Basic Store subscription which starts at $21.95 per month.

Does Terapeak Work With Amazon?

Does Terapeak Work With Amazon

Terapeak does not work for Amazon sellers and only provides detailed sales data for the eBay platform.

Prior to being acquired by eBay in 2017, Terapeak was an eCommerce analytics company based in Toronto that used to provide analytics data for both eBay and Amazon.

However, eBay removed the “Terapeak for Amazon” tool post-acquisition and integrated Terapeak into its website to make it exclusive to eBay sellers.

How Do You Access Terapeak On eBay?

Ebay Seller Hub

To access Terapeak on eBay, go to the “Research” tab in the “eBay Seller Hub” and then click “Terapeak product research” in the left side menu.

If you’re subscribed to the Basic Store plan or above, you’ll find “Terapeak sourcing insights” right below “Terapeak product research.”

How To Use Terapeak

How To Use Terapeak

Here’s a step-by-step tutorial on how to use Terapeak:

Step 1: Find Products Using Terapeak Product Research

Terapeak Search

Use “Terapeak product research” to find products to sell using a keyword or one of the following identifiers:

  • Manufacturer Part Number (MPN)
  • Universal Product Code (UPC)
  • International Standard Book Numbers (ISBN)
  • eBay Product ID (EPID)
  • European Article Number (EAN)

You can also choose to refine your search results in the following ways:

  • Use long-tail keywords to find products with low search volume and competition. For example, search for “iPhone 14 Pro Max 128GB” instead of “iPhone” or “iPhone 14 Pro.”
  • If you search for multiple keywords, you’ll find listings with all of those keywords. For example, if you search for “iPhone 14 Pro Max 128GB,” you’ll see listings with all of the keywords “iPhone + 14 + Pro + Max + 128GB”. If you use too many keywords in your search, Terapeak may return 0 results.
  • Exclude search results by adding “AND NOT” or “-” before a keyword. For example, “iPhone 14 Pro Max 128GB – Gold” will exclude listings with “Gold” in the title.
  • Add “OR” between keywords to add more product options. For example, “iPhone 14 Prox Max AND (128GB OR 256GB) will show results for iPhone 14 Pro Max with 128GB and 256GB.

Step 2: Use Filters To Refine Your Search Results

Terapeak Refine

Above the search results, you’ll see a series of filter options that you can use to refine your search by eliminating unnecessary products.

1. Select the period for the data you need, such as “Last 7 days” and “Last 30 days.” Terapeak can return up to one year’s worth of sales results. It’s best to filter for an entire year since you get a better idea of sales and demand for the selected product.

You can also filter by the marketplace, such as,, etc.

2. Select “Condition filter” to filter products by their condition. For example, select “Used” if you want to sell used items. Then select the “Format filter” dropdown and choose one of the following listing formats:

  • Auction
  • Best Offer Accepted
  • Fixed Pricing

3. Choose a price range. Consider eBay fees, product costs, and shipping fees when you set the minimum price.

Step 3: Analyze The Search Data

Terapeak will now show you two sets of results:

  1. Sold: These are items sold in the specified time frame.
  2. Active: These are active or live listings.

For the “Sold” items, you should see the following eight metrics:
Terapeak Sold Metrics

  • Avg sold price: The average selling price for listings in your search results, excluding shipping costs. Helps you decide how to price a product.
  • Sold price range: Shows the lowest and the highest sale price of the product. Best when using long-tail keywords; otherwise, pricing for unrelated products may get mixed into the data.
  • Avg shipping: The average amount buyers paid for shipping;  excludes listings that offer free shipping.
  • Free shipping: This is the percentage of products sold with free shipping. A high number indicates that you may need to offer free shipping to be competitive.
  • Total sold: The total number of matching items sold within the specified time period.
  • Sell-through: The percentage of similar items sold within the specified period. You can use the sell-through metric and the total sold metric to estimate the number of similar items listed.
  • Total sellers: The number of eBay sellers who listed similar items during the specified period.
  • Total sales: This is the total revenue of all the items sold. The total sales metric helps you know the eBay market size for a product or category.

“Active” listings should display the following metrics:
Terapeak Active

  • Average listing price
  • Listing price range
  • Average shipping
  • Free shipping
  • Promoted listings

All of the above metrics are similar to the Sold items metrics except for Promoted listings. Promoted listings are the percentage of active listings being promoted using the Promoted Listings Standard feature.

Below these metrics, you’ll see different charts and graphs showing trends for the product over the specified time period.

Terapeak Graph

You should look at the “Trend line” in the graphs. A trend line with a distinctive peak indicates months with higher demand for the product.

Step 4: Perform Optional Category Research

If you have access to Terapeak sourcing insights, you can use Terapeak to find popular and trending product categories.

Go to the “Terapeak sourcing insights” section to research categories and search for the one you’re interested in using a product keyword, ID, or name.

Terapeak Category Search

Alternatively, you can browse and select a category using the list below the search box.

Terapeak Sourcing Insights

You should see these four metrics:

  • Search volume: This is the number of search queries for the selected category.
  • Active listings: This is the total number of active listings on eBay.
  • Search-to-listing ratio: The ratio of category search volume to the number of listings in the category. A higher search-to-listing number indicates lower competition. For example, if the search volume is 1000 and there are only 100 listings, then the search-to-listing ratio is 10.
  • Sell-through rate: A percentage value of the number of items sold divided by the product inventory. The higher the sell-through rate, the higher the number of products sold.

Click on the category to expand it and see more details.

The following two filters will allow you to refine your search results:

  • All formats: Choose either Auction or Fixed price format.
  • All conditions: Choose a product condition. If you’re selling brand-new items, it’s best to choose “New” instead of “All” conditions to avoid skewing the data.

Below the filter, you’ll see the following three graphs:
Terapeak CTR

  • Click-through rate: This is the number of clicks a product receives divided by the number of times the product is displayed in search results.
  • Total listings over time: This is the total number of listings displayed in a specific period.
  • Total items sold over time: This is the total number of items sold over a specific period.

Scroll down to see these three tabs below the graphs:
Terapeak Opportunities

  • Top opportunities: These products aren’t necessarily top-selling but generate good impressions and clicks and have a lower return rate than other products.
  • Explore item specifics: You can check product-specific details in this tab. For example, this section will give a product breakdown and variations to help you understand which variants sell more. For example, if you’re looking to sell iPhone 14 Pro Max, you can check which color sells more.
  • Top listings: These are the best-selling listings in the category.

You can click on the products individually to do product research using the Terapeak Product Research tool.

Terapeak Products

After exploring the category, go to the top of the page and click the “Save category” button on the top right to save the category and compare it with other categories.

Then go to the “Saved categories” section to get a better idea of which of your saved categories show better metrics.

Limitations Of Terapeak

Limitations of Terapeak

The main limitation of Terapeak is that it only shows data from the past 365 days. You can’t check sales data or trends beyond that time period.

The other limitation of Terapeak is that the tool only provides revenue numbers and not the gross profit for every sale made.

For example, some high selling products on eBay are sold at wafer-thin margins or at heavy discounts which can artificially inflate the sell-through rate.

Make sure you check prices with your wholesale suppliers to calculate your potential margins before deciding to sell a product.
