Most Popular Searched Keywords
Before setting up a website, you have to find out how popular it is on the web. The reason being, if the topic is a flop, it’s not worth even building a website on it. This may sound very simplistic, but if no one is interested in the topic, chances are very few will land on your website.
If you want to build a website on wallpaper, but that keyword got only 1000 searches last month, I wouldn’t waste my time on anything related remotely to wallpaper. The main keyword wallpaper doesn’t even get enough hits, let alone the more specific sub-topics on wallpaper.
For most websites, you want something that gets tens of thousands of hits on the main base keyword and at least a few thousand on your niche website based off the main keyword. For example, if you were doing a baseball team blog the main keyword would be “baseball blog”. Your specific keyword you are targeting for your team website, would be “[teamname] blog”. Remember, it will take months or years to get high ranking for the keywords you want. In the meantime, you will be getting searches from mainly the less popular longer keyword phrases, that usually will land on your individual pages inside your website.
Once you have found that popular topic that interests you, then you can build your website’s content, title, and domain(maybe) around that keyword. Choosing a domain is tricky decision and isn’t always based on SEO or keyword popularity. Sometimes a memorable domain name is the best way to go long term.
I have found a Keyword Selector Tool from Overture, that shows how often each keyword was searched in Yahoo search engine last month.
So you finally have figured out the topic of your website and which keyword gets the most searches. Now you are ready to build your website and register your domain right? Not so fast!
There is one other thing to remember, competition. Type your keyword into Google and find out how many website results show up in number. Ideally you want to focus your website(and maybe your domain) around a keyword that is searched a lot, but there isn’t as many websites that show up in results. Often the medium volumed searched keywords are better because the ratio of searched words to websites is higher. Too many webmasters overlook this and simply go for the main keyword. If you pick a less popular keyword but there is much less websites on it, that means there is a higher chance of them coming to your website.
So in summary, the most popular searched keyword is not necessarily the best one. Sometimes picking a less searched keyword that has less website competition, is better than the most popular keyword on that topic. You will have to calculate each keyword as a ratio and find out which one has the most favorable ratio.
Once you have done all this to find the best keyword, create your website(and maybe domain) around that keyword.

You have to be careful picking the less popular keywords just because once you dominate it there’s nowhere else to go. I’d rather take on something that is more difficult with a greater long-term reward. OR perhaps you could do both. Nobody says you can only build one store/site.

You got a good point. Having more than one website targeted for different keywords among the same keyword group can work.
