You need sometimes to choose a topic without the keyword tool
I was thinking, If some reader visited my website and enjoyed an article that I have chosen based on the keyword tool or Jaaxy, he would probably look for another articles in my website that have to be attractive and indicative to my real opinion and my real me.
So I thought it would be better to choose 2 topics based on keyword tool and 1 topic without keyword tool, as sometimes you would have an idea that no one has searched for on the internet, so if you search for a keyword for this idea on the keyword tool or Jaaxy, the result would be less than 10, but in fact, if one reads that unique article on your website, he would find it interesting and creative, and he might become a frequent visitor to your website, and that's what you want.
So let's make categorizations for the topics you're writing about:
1- Topics to get traffic to your website, so you use keyword tool to choose them.
2- And topics that give your website the uniqueness and originality.
