Lets rock those keywords

First, go to this website - http://keywordtool.io, now you have several options to choose from let's break them down.

As you can see we have a menu with several options, these give us plenty to choose from.

Just by switching tabs you can search for keywords in search engines, google, bing, youtube, amazon and even on app store.

Select the country of the search engine and the language you want to search.

Notice, some tabs have fewer country options than others. ex: you can only search AMAZON in countries where they have amazon ;)

For this first example, I will search google in google.com in the English language.

I will do a search on a competitive niche, such as "work at home" let's check the results...

I got 374 unique keywords out of that 3 words

Now we need some fine tuning.

You can now copy all to your clipboard or export those keywords to a Excel or CSV file.

I also marked the negative keywords because it's a useful resource to have, If you mouse over the question mark it will give you the perfect explanation, imagine you are searching for apple (fruit) you can use the negative keyword tab to write down, mac, iPod, iTunes, iPad and it will exclude those from your search result. Sometimes this can be really useful.
