Finding what's hot now How can we find it? Simple Just go to Alexa Website and you'll get this:
There you can see what's hot topics now. Find topics that related to your blog/website content and remember it! As example, I'll take "keyword tool" that related to this blog. If you can't find there, try to looking on Alexa What's Hot page. You'll see more topics there. OK?
Finding the right keyword Now we'll use tool from Google, Google Keyword Tool. You can find best keyword there.
Also, you can go to "Advanced Options" to set additional rules when you searching the keyword, ie: location, language, etc. You'll get the result:
Click on "Global Monthly Searches" to sort the results based on the Global Monthly Searches. There you can see the most widely used keywords on "your topic". In my case, "keyword tool" and "tool keyword" is the most used keywords.
Use these keywords on your website/blog content Last step, use these most used keywords! You can use it on your content, title, tag, permalink or anything you want. Personally, I suggest you to use it to be your title or permalink. But it's up to you :)
