From the early days of my domaining career, the most difficult thing for me was BIN setting, especially for BIN only listings. The usual hurdles I have to overcome: 1. If i set it too high, i lose leads. 2. If i set it too low, i leave money on the table. 3. How to find a sweet spot, which drives on a win-win situation for both buyer and seller? 4. What factors I have to study to decide? 5.Which tools I have to use? 6. Each domain is a special case. No, "one decision for all", it will not work. One thing that I understand is that I can't satisfy every buyer. Each buyer has different budget and lower or higher interest to buy a domain name. Having said that, I am sure that all this is related with buyer's psychology. Psychology is one of the most important factors not only in domaining, but generally in life. The key for me is to make the possible buyer to feel that he doesn't burn his money for nothing. He must feel, from the first time he checks your listing, that he found a true value for money chance. Happiness and enthusiasm doing for serious investment, or to establish his website. Positive feelings. It doesn't mean you have to lie him. Quality never lies. Don't underestimate end-user mind. Be honest. The available tools I can use can really help me. Searching similar past sales (namebio.com), checking domain's history (archive.org) and of course the search engines (google.com) are only some of the tools which are free and available. The question is, are the tools enough to solve all my problems? Unfortunately, the answer is no. I need something more to take the right decisions. This is what I call "Market Awareness". It's the ability I have to understand the current value a domain has, but also it's potential. In which degree a name can be useful in a fast changing world. I always set my BIN's in one market. This must be done for two main reasons: 1. In case of two different buyer's hit your BIN in the a and b marketplace, I will be in big trouble and possibly get banned from one marketplace. 2. Make offer listings give the buyer the important "space" to send a lower offer if he has limited budget. It's different story if I accept or counter. The incoming lead is the priority. It's worth to mention that I cannot sell all the names in one year (season). This occurs even if an investor has top quality portfolio. A small percentage of the names will be sold per year. I have to deal with it. Please keep in mind that sellers with many sales still have a huge portfolio with thousands names inside. This doesn't mean of course that they are successful. But playing with the numbers it's another story, allowing them also to lower their BIN's. It's good for them if it is done right, but now we talk about an average portfolio (let's say up to 2000 domains). The art of setting the BIN can be very challenging journey. However, I am sure that a serious investor will improve his skills and finally be able to take the better pricing decisions. The right BIN is the BIN which both buyer and seller want and drive them to a valuable agreement.
