I ran across a site today called Terapeak. Apparently its a popular site with the eBay community so you may have heard of it but I never have. Signed up for the monthly service, something like $30 a month to give it a go and I was blown away. Not really sure why I created 48 sites now without this site. You can check out all of their demos to see what exactly it does but whats important for you and me is that it will help you find your niche.

Heres why I love it!

Shows all the hot categories, searches, products, ect.
Breaks it down to where you can see percentages of the listings if it sells
Shows you if they are spending more money on their listings and for what. Featured, Bold, ect.
Browse through categories and it shows you the top sellers.

These are the items for general stats

Total Sales
Total Listings
Successful Listings
Total Bids
Items Offered
Items Sold
Bids per Listing<
Sell-Through
Sellers per Day

Finally the best part about Terapeak is they have what they call a Sell-Through percentage. This basically tells you how many listings actually sell. The higher the percentage the better the niche. I believe this site was made more for eBay sellers but its an amazing tool for eBay affiliates.

It only took me about 30 minutes using it and I found 5 great new sites to make. Dont think I would of ever thought of these sites without it.
