Over the past several months, AERS has been conducting studies that analyze the impact of Terapeak’s marketplace research tools on eBay sellers’ sales and success rate. With the results from the first group of sellers now compiled, it’s clear how valuable transaction data can be to online business owners.

The group of participating eBay sellers was selected randomly, and features specialists in collectibles, home safety products, antiques and more. Eight performance indicators were tracked for three months for each seller. Statistics related to each indicator were compared on a pre- and post-Terapeak basis, and were then used to determine a percentage of growth or decline.

Some sellers showed improvement in every business facet, while the improvement of others focused on specific statistics. And when averaged across the entire group, every indicator showed at least some improvement.

Below is a table of indicators tested, followed by sales growth statistics:

AERS has always stressed the value that lies within every ecommerce merchant’s transaction data, and with help from this Terapeak case study, that advantage is made clear.

Here are a few anecdotes shared by case study participants:

[Terapeak] has enabled us to identify a range of products that our competitors are selling that we previously weren’t! And, just as importantly, has helped us to decide which products our competitors have not been able to sell, and [which] we shouldn’t be stocking either! –economiccomics

That’s where Terapeak comes in handy for me. I call my husband (who is more than happy to stay at home while I foray to yard sales and auction previews), tell him to get on Terapeak and check out items while I’m still at a sale. In many cases, that’s been very helpful in determining what or what not to buy. –6regentspark

I must say that [Terapeak] has changed how I do business and it has also allowed me to look into other markets that I might not have perhaps looked at before. -global-gadgets

We love the Terapeak service. –shiponsiteyng

I cannot say enough [about Terapeak]. Our customers now know that when we say we “Terapeak-ed it” that it’s good info. It makes our life so much easier when we can show people the true ebay value of their items. –quick2sellpgh

AERS and Terapeak thank all those who participated in the study.
