Congratulations on your recent sales.
It's important to note that with 300 names in your portfolio, you are carrying a $3,000 annual liability (assuming $10 renewals).
The low prices and lower quality of your names is going to make it hard for you to turn a profit each year on your portfolio. You would need to sell 15 domain names at $200 each, on average, to break even. That's a 5% turnover rate on 300 domain names. That's pretty high for a portfolio of lower quality names.
Increase the quality of your names and raise your prices. Aim for a $995 sweetspot at first, paying no more than $99 for each name. We sold five .com names at $995 in the past week. These were some of our lower quality names that we marked down at the beginning of May.
Better quality begets higher prices and returns on investment, while also decreasing financial risks -- the risk that you'll end up simply dropping the names, worthless, out of your portfolio at a future date due to lack of end user interest and sales.
Finding quality domain names: Study the names that DotWeekly.com finds and reports that large corporations and well-funded startups are buying in its "Domain Movers" series. Go through at least two year's worth of Jamie's posts. Write down all the names that are clearly not a large company's defensive registrations that include an existing brand name or trademark. Notice the patterns. Categorize them into logical categories. Do the analysis to teach yourself what kinds of names that CMOs and CEOs are green-lighting for purchase using corporate funds. Imagine the CEO saying, "They want $35,000 for the domain name?? God dammit! It's the perfect name for our new venture. OK, whatever. Just go buy it."
Going through this process will teach you the kinds of quality names – i.e., positive connotation, "make sense" names using one or two simple English words that are hard for the average American with a high school education to misspell – to be on the lookout for at auctions and to start paying up a little more to acquire. You can, in turn, price these quality names well into the four and five figures. Large sales of that scale make turning a profit on a 300 name portfolio far easier to achieve, even if you only make one or two sales a year from here on out.
