A mate asked me a few years back what I thought the domain fashiondirect.com.au was worth - I said it was a nice name but it was only worth low $XXX because it had no search volume...
He sold it for $3000 on the brandability of the name.
Whoops...
I've had lots of offers on brandable domains (mainly .com) and sold a small number of them.
When I first started buying domains I bought quite a few terrible brandables (Rick.S would call them pigeon shit), but as time went on I stopped buying brandables and focussed on products, industries, places etc (still bought a lot of duds mind you!).
Once I had learnt enough to know I wasn't just throwing money out the window (or at least less likely to be), I started buying decent brandable domains that myself or other businesses would actually want to build a brand around.
Back to your story, I've also had $0 or low $xxx appraisals from people (on this forum in fact) and then subsequently sold and had offers for those domains for $xxxx and up.
Appraisals are inherently difficult. I've probably gotten it wrong plenty of times when I've put in my two cents on a domain. Like many others, there are products, markets and niches that I understand and lots that I don't.
With brandables it's tricky because they could be applied to potentially lots of different uses, plus you often won't have metrics such as search numbers to guide you. For this reason core value elements such as the following are even more important for brandables:
Memorable
Easy to spell
Passes the radio test
Fits with a commercial brand image to pursue one or more markets
Etc...
I particularly like brandables that define a business type, but also have broader appeal. I've bought a number of these now and they seem to be pretty popular. Most of them have minimal 'exact match' search numbers using Google tools, so if that's solely how you assessed value - you would see them as having a very low worth.
Here's an example (two of mine, .com, .com.au etc):
The definition is a cheese making business - but it could also be used for lots of stuff, such as a cheese shop (there are a few that are), grilled cheese truck/cafe (had offers in that area), a site about 'cheesey' stuff (cheesey movies etc) and so on.
It's obviously best suited to the hospitality industry, but it sounds catchy and could be applied to other areas.
It's short, memorable, easy to spell, passes the radio test and has commercial application as a brand - that to me is how to pick a good brandable. I should also note those examples are not for sale.
Would be great to see some more examples from others. Ringstinger is a fantastic story!
James, 'congrats' is a fantastic domain! It certainly tickes all the boxes I mentioned
