※データの切り替えでamazon.comでも検索頂けます。

Seller research function.

If you want to quickly find profitable products on Amazon, Seller Research is recommended.

Seller Research is a research method that focuses on sellers, not products.

Normally, you would find one profitable product in a single research session, but with Seller Research, there is a possibility of finding a large number of profitable products all at once.

However, conducting Seller Research manually can be challenging, but by using Eresa Pro, you can easily do it with just a few clicks.

Usage Method for Seller Research Feature 1:

Bulk Variation Search Function.

When researching products on Amazon, you may come across catalog consolidation, where variations of the same product, such as different colors or capacities, are grouped together.

From the buyer’s perspective, the products are well-organized and easy to navigate, making it very user-friendly. However, from the seller’s perspective, it becomes difficult to determine which variations are selling well.

With Eresa Pro, you can instantly see which variation of a product is selling the best among all the variations with just “one click”!

Usage Method for Bulk Variation Search Function:

STEP
“Access the Eresa page for the product from earlier.”
STEP
Click on the “Variation Search Function” (magnifying glass icon) located next to the Variation Display field.

This icon will only be displayed if variations exist.

STEP
You can check the “Number of Ranking Drops” for each variation in the displayed list.
ランキング降下回数=注文数=販売個数
STEP
You can identify the best-selling products in descending order based on the number of ranking drops.

It was found that most colors of this product had a very small difference, but the “750ml Matte Black” variant is selling the most despite having a premium price.

Function to display the lowest prices by condition & state (including shipping costs and excluding shipping costs).

How to use the function to display the lowest prices by condition and status (including shipping and excluding shipping):

STEP
Click the 🔻 arrow next to the lowest price for each condition.
STEP
The lowest prices for each specific condition (including shipping) will be displayed.

Cart Box Acquisition Sellers & Acquisition Rate History Display Function

When selling new products on Amazon, one of the most crucial factors is acquiring the Buy Box. Winning the Buy Box directly impacts sales, so it’s essential to strive for it by implementing appropriate strategies.

However, winning the Buy Box is not guaranteed even if the criteria are met. There are instances where it may not be obtained, depending on the product.

Therefore, it is necessary to conduct thorough research on the products beforehand to assess whether the Buy Box can be won.

With Eresa Pro, you can find the “Cart Box Acquisition Sellers & Acquisition Rate” displayed on the product details page. This feature provides information about the sellers who have won the Buy Box and their acquisition rates.

How to use the Cart Box Acquisition Seller & Acquisition Rate History Display feature:

STEP
Click on the “Cart Box Acquisition Rate” displayed in the product details.
STEP
The “Cart Box Acquisition Rate” feature displays a list of sellers who have acquired cart boxes along with the acquisition rates, the latest acquisition date, and cart prices for various periods (30, 90, 180, and 365 days).

You can access the Seller Research with just one click by clicking on the magnifying glass icon next to the seller ID.

CSV output function.

With Eresa Pro, you can export the displayed product data in the search results to a CSV file. This allows you to manage and view the data in tools like Excel or spreadsheets.

How to use the CSV export function.

STEP
Click on “CSV Export” at the designated location.

Locations where the CSV export function is available.

  • Normal search & advanced search
  • Favorites
  • Seller research
  • Bulk product search
STEP
The search results will be exported to a CSV file.

Sales quantity prediction function

By specifying the major category and ranking on Amazon, Eresa’s proprietary algorithm will use past sales performance data owned by the company to display weekly and monthly sales quantity predictions.

This feature is currently in beta testing phase.

How to use the sales quantity prediction feature.

STEP
Access the “Sales Quantity Prediction” from the menu.
STEP
Specify the large category and ranking to perform the search.
STEP
Weekly and monthly sales quantity predictions will be displayed.

Note: Since the rankings constantly fluctuate, it is recommended to specify parameters like the 90-day average ranking to obtain more accurate numbers. For low-ranking products (5 digits or higher), the ranking drop count may provide more accurate results at times.

Example: Nintendo Switch console.

The ranking drop count for the past 30 days is 231 times, however…

Based on the prediction from the 90-day average ranking, the monthly sales quantity is estimated to be 15,567 units.
