I want to know if this is a good idea, some how to get more traffic to my main site. I found a good Keywork, and this keyword, I want to make is as a domain. so when people search for this Keywork, come to my domain. This domain will send then to my main site which hase relative contents. Thanks for your comments
Does this keyword has sufficient traffic? weak competition? and do you actually have good information to write about this keyword? if yes to all three then you've struck gold, go for it
Choosing/finding a good keyword is a great start. You then need a bunch of "related" keywords to add content to the site and make it more appealing. Make sure you only focus on ONE keyword per page/post.
It's always smart to put the keyword you are trying to target in the domain name you are purchasing. It makes it easier for your customers to find you. But you want to make sure that keyword is being searched and that there are buyers for your product. A great keyword, with high search volume, and people who rarely spend money in the niche is dead in the water.
its definitely a good idea. if you can get a domain name exactly matched to your main keyword then the result that you will get will simply be awesome. so try it out. thanks
