Over the past several months, Terapeak has been conducting studies that analyze the impact of market research on eBay sellers’ sales and success rate. We’re very grateful to all those who’ve participated, and with the results from our first group of sellers now compiled, we’re excited to present the outcomes!

A little background first: the group of sellers was selected randomly, and features sellers specializing 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 nearly 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.

Here’s a breakdown of the group averages and best results:

As you can see, those are some pretty impressive numbers!

One of the most entertaining parts of the study was researching each seller’s highest priced times. Among the most curious results: a vintage men’s watch worth over $2000, model train accessories, Marilyn Monroe memorabilia, X-Men comics, jewelry, radio equipment, and collectible coins.

All of the participating sellers were a pleasure to interact with, and all were generous with praise for Terapeak’s research tools. Here are a few anecdotes they shared:

[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
