wwwdomain.com typos are better in general than typos such as googke.com in terms of CTR.
First off, the CTR in general is determined by the type of visitors viewing the site. I know typos such as googke.com, were for sale once before and I remember them having very low CTR 1%-5%. Same thing with my youtube typo, I have avg 3% CTR. But typos that I own of credit card companies and banks that appeal to older people get a 20-35% CTR.
Now I looked at 2 domains of my buddy's. I'm not going to say what they are but the wwwdomain.com version has 40% CTR, while the other one, which looks such as "domian" (notice the typo of the "i" and the "a") gets a 30% CTR. Same advertisements, same types of visitors.
Also, another thing I noticed. If you have what I call, a "illiterate" typo, such as krysler.com or yawho.com, you will usually have an above avg ctr. Why? Because the people that are visiting these types of typos aren't smart enough to spell out the domain correctly, therefore they aren't smart enough to avoid the advertisements. And I have a few domains that prove this.
Overall point is to know what type of visitors you have. Teens? Adults? Women? Men? Women usually get the highest CTR, while teens, gamers, developers, or even domainers like us have the lowest.
I am able to calculate an approx, I always calculate at a minimum. I never try out the domain, most sellers don't even agree to it. But if you can test the domain for a few days then that only works to your advantage!
