Flippa,one of the best marketplace for buying and selling websites,which was founded a year and a half ago has just released its 2010 Year in Review.

Over 150,000 bids were placed on Flippa website/domain auctions in 2010 which drove the nearly 20,000 successful auctions and private sales we saw for the year. This amounted to almost $21M worth of websites and domain names being sold on the industry’s most active marketplace.

We had almost 2 million unique visitors come to Flippa in 2010 according to our analytics. In terms of the active website buying and selling community, we had our 90,000th user registration in 2010 which goes a long way to explain the 1.6 million logins we had for the year!

Another sign of the booming growth in the Flippa user community is that our support team managed nearly 20,000 customer queries. On a less positive note, the team suspended or banned over 2,300 user accounts in 2010, primarily for registering duplicate accounts, shill bidding or not following through on a won auction transaction – the types of users the rest of the Flippa community won’t miss!

Our analysis also showed that Flippa users put websites/domains on their watchlist over 130,000 times during 2010 and around 135,000 comments were left on 70,000 listings.
