Using the Google Search-based Keyword Tool, you can find keyword phrases from Google’s own search results database AND you can also find categories Google considers relevant to those keywords.
I figure accepting Google’s advice, when they’re willing to provide it, is very useful for seo optimization. It’s also a great way for me to come up with new ideas for articles.
So check out this video on how to do keyword research with Google’s Search-based Keyword Tool and don’t forget to check out my video on choosing the right keywords with Wordtracker as well. Wordtracker does things that Google doesn’t so I think both tools are valuable.
