Basically, you enter in the name of your blog’s niche and the tool will spit out a bunch of related keywords. So, let’s pretend I have a sports car blog. I typed in sports cars in Google’s tool. Here’s a sample of what came up.

* classic sports cars
* top sports cars
* new sports cars
* sports car pictures
* cheap sports cars
* bmw sports car
* racing sports cars
* luxury sports car

Second, you can use SEMRush, another SEO tool, to discover keywords that generate traffic for other sites. With this tool, you simply type in the URL of a site without the “http://” and the tool will show you 1000 of their keywords. It’s a good idea to choose sites with similar popularity as yours. For example, choose blogs with similar PageRank and Alexa Rank.

SEMRush has a monthly fee. However, you should be able to do all your research in a month and you can save your data in Excel or csv format.
