When it comes to running successful online auctions, every detail counts - including how your bidders are identified. At AuctionMethod, our auction software gives you flexibility in how bidder usernames are handled. But what’s the best approach? Should you show bidder IDs? Let them pick their own usernames? Or keep everything anonymous?
In a recent LinkedIn article, I shared some research and best practices for user identification in online auctions. Whether you’re running large B2C auctions or niche B2B events, the way you handle usernames can have a real impact on bidder behavior, engagement, and overall success.
Let’s break it down.
Usernames might seem like a small detail, but they play a big role in how bidders engage with your auction. Here’s why:
Transparency builds trust. When bidders can see who else is in the game (even if it’s just a user ID), it gives them confidence that the auction is legit.
Behavior is influenced by visibility. Bidders often react differently when they see who they’re up against - especially if they recognize the username.
Competition gets personal. When usernames are visible, some bidders dig in just to beat a specific rival. And that can drive prices up.
AuctionMethod allows you to either assign system-generated bidder IDs (like “Bidder #29312”) or let users create their own usernames (like "2Fast4U"). So which option is best?
For B2B or small bidder pools: Stick with system-generated usernames. These events are usually more transactional, and a layer of anonymity can prevent bidders from targeting one another based on known identities.
For B2C auctions with larger audiences: Let users create their own custom usernames. It personalizes the experience and can stir up some surprisingly fierce bidding wars.
Back when I was running WestAuction.com, we had one longtime bidder with the username ‘outbidu’. It was brilliant... and brutal. I can’t tell you how many times I heard from other bidders who admitted they stayed in the auction way longer than planned just to try and beat ‘outbidu’.
They were annoyed. They were determined. And they kept bidding.
That username probably earned me a pretty penny, all thanks to a little psychological nudge. It’s a great example of how usernames can become part of your auction’s culture - and even your strategy.
Another option in AuctionMethod’s software is whether to display usernames in bid history. Admins can always see this info, but you get to decide what bidders see.
As I mentioned in the LinkedIn article, it’s usually best to show some form of bidder ID - even if it's anonymized. It gives participants context and creates a more engaging, competitive environment.
User identification settings aren’t just technical preferences - they’re strategic tools. By understanding how usernames affect bidder behavior, you can tailor your auction experience for transparency, trust, and higher engagement.
