Really? Why?
I would have though different why are these bad specifically?
Brandability - unless you are branding a nonprofit or community site that would be associated with a .org, a .org is a poor choice for branding. A .co would be more appropriate for spanish terms branding, or at a minimum, a service/product highly sought after in that country.
Search Demand - Although there are exceptions, a .co with less than 1000 exact match searches isn't really a gem. A .org at 2400 exacts is better, but there are plenty available with that or more.
Marketability ROI - what are you going to do with chickenfingers.org that would make you money? A potential buyer would have to see a return on investment to value the name. For kayakrentals.co , why would a potential buyer spend big dollars on a name he could not brand, in a country extension that he doesn't operate in, and where he would lose much of his traffic to the .com?
Advertiser Demand - what is the CPC for these terms? See again marketability/ROI
So, before registering any more names, always ask these questions - and answer honestly:
1. Is this name brandable? Would it sound good on TV, easy to spell, not easily misunderstood, short and catchy?
2. Are people looking for this term? What is the search volume, and what do names with similar volume sell for in this extension?
3. Is there a return on investment for a buyer? How Much? If this were developed, how much traffic and revenue would you expect to make from it per year? Take that number and divide it by 10, subtract out what it would cost to build the site, and you have your value.
4. How much are advertisers paying for qualified traffic in this niche? Again, evaluate
#3 for a return on investment.
5. Is there any existing traffic to this name either type-in or old links traffic? How much? and again see
#4 and
#3
Schools out. It is OK to play around with low end names - that is pretty much my business model and I see a lot of people doing well in the XX to XXX range. But, if you are just flipping names, you have to do much better than these. If you are buying junk, you need to be able to develop some basic sites to try and eke out some earnings on your portfolio and hope you can trade up later, or catch a lucky break. Read the forums and see what stuff sells for - figure out why it sells for what it does, and then look for names where the cost is less than those values. If you don't know why some names suck, you need to do more research.
And even then, we all buy a real stinker here and there - be prepared to drop at least 10% of any hand-regs each year.
