The domain industry

Later, I realized that people search for certain things but not all. A phrase can be very existing in search results but few or very few people looking for it.
So called domain resellers look for domain names that correlate to common search words/phrases or words/phrases that just sound so good that the potential is obvious.
Other specialized names can be valuable only to end users.
End users are companies, manufacturers or distributors etc. They may sell certain items but in a niche where they have their customers. For those, any domain name describing or naming their products or services can be as valuable as how much they would consider to pay, to get hold of that name. Otherwise someone else or a competitor would get it.

So finding domains today that are free today requires some skill. Because there are a lot of available domains. Even .coms. Of course most are gone but if you look in a broad way, you still find that some or a few percent are available. And when I have seen them, I have usually taken them, at least those who seemes to be best. But I have lists with untaken domain and they disturb me a bit. I see the potential but for all there is, I cannot reg all of them. No, and you have to choose those you view as best.

When looking back, I have often found that I have changed, like how could I reg that one I should have taken that one instead and so on. Probably that thing can´t be avoided but sometimes you may even switch back to the first point anyway!

Nevertheless, since so many -coms are taken, them what to do? Being very creative can sometimes output smart names that are available but then when these are taken too.. well you may have to give up.

More and more, other (country) tld-s have become more popular since you can still find a lot of single words available and with the probability in mind that they will be more valuable in time, it can be a good investment.
However I do believe right now, that the extension that will gain most is the old .net. Net is since a long time and today, the second most popular extension.
All the single words are taken as .nets (and as .org, .info too.) though you sometimes find some single words in plural form that are .net available.
More and more, phrases already taken as .com are being taken as net.
