This is one of the main reasons I've titled the post "SEO for Dummies". It's because most people would do anything to get a domain name with their main keyword in it. They even buy domain names with like 20 - 30 characters in them - sheesh! There's a limit people...
If you're building a website that's aimed at success you're definitely going to be providing something that's useful. In that case wouldn't you want to build up a brand name instead?
Among the top sites can you name a few that have "Keywords" in their domain name? There may be a few, but none come to mind.
On the other hand popular sites such as: Google, Yahoo, Facebook, Bing, Amazon, Mashable, Reddit, StumbleUpon, Pinterest and various others aren't even actual words in most cases - Now that's what we call branding.
Do you have the notion that keywords in your domain name are going to help you rank better? Well, the sad part is that it's actually true. But, it's not going to be the case for long.
What Would I do?
If I were to buy a domain name (And I have), I wouldn't bother about getting the keyword into the domain unless I'm only interested in search engine traffic and wouldn't want people to return to the site on their own. You should know that people don't usually trust long domain names as they seem fishy.
I doubt you'd find short tail keyword domain names available as they're probably already taken and if they're up for auction, be ready to shell out 1000's of dollars.
Therefore, I'd pick something that's catchy and try and build up a brand name instead.
Just summing it up:
Keep it Short and Sweet
Try and make it sound catchy - That's better for branding
Avoid use of Numbers such as 4 for "for" and other short forms, people may not remember and probably land up on a competitors site.
Don't use Hyphens in the domain name
If you're buying a domain name, make sure it doesn't have any spam action by the search engines. if you're not sure, it's best to buy a new domain name.
Keyword Research - Key Phrase Research, Rather
Every website or article that you publish is going to be directed to a certain group of people looking for something specific. There's no way search engines are going to know what your article is unless you tell them.
The only way you can do this is through the body of the article, tags, descriptions, excerpts, breadcrumbs, the URL and a lot of other ways. So how do you come up with the right phrases that you must incorporate within your article?
NOTE: Don't write articles around keywords, instead think of what you want to write about and then conduct a little research before you actually write in order to know what your audience is typing into search engines when they plan on reading about something you intend to write.
