SEO is stand for Search Engine Optimization. in seo two type of work are main. The one is on-page and second is off-page.
Seo work start with on-page optimization. In on-page optimization the first brainstorming task is keyword research. I say brainstorming because you take quick and accurate decision that what kind of keywords will visitors and which are the best keyword that drive the targeted traffic. You can use keyword research tools that are available in vast amount on the internet.
All these tools help you to choose right keyword for your site. Formally these keyword research tools have past and present record that guide you that which keyword is now more use by visitor. The tools have some chart and some calculation that are evaluating the current status.
Generally this tools display the number of current traffic and visitors. You must choose those keywords that have less competition and more traffic. You should calculate the ratio of traffic and competitors. If some keywords gives minimum value of this ratio. Than select that keywords as main keywords. But remember choose keyword less famous. This cause you get some traffic from this less famous keywords. And when you get enough traffic than you can use more competitor keywords.
If you select famous keywords as main keywords at the beginning, you can't get enough traffic and also you notice that your site rank is not improved. When the iron is so hot and red than that is the right way to strike the hammer. So it the right way to choose less common keyword, get some traffics and than use famous keywords as main keywords that have really good traffic.
Most of the seo firm uses this kind of strategies to choose keyword. After choosing right keyword it is necessary to use in the right place and right time. It the matter of ethical seo activity. If you use your keyword more than limit and don't follow the rules so once you get good ranking in just in few days but when you caught by any search spider it banned your site. This may your site never listed in all the search engines. So be careful and more conscious about keywords research and keywords stuffing.
These are the basic steps to choose keywords and also use it. But the thing is that it more clear when you practically use it. I hope this post will help you to know about keyword search.
