One of the most important activities to undertake when starting to think about SEO or PPC is keyword research. One important step to do is coming up with a list of related keywords. If you start a site about mortgages, what other related keywords are there? Wouldn’t it be nice to know what keywords Google’s algorithm’s thought were related? I went to a Google AdWords Seminar last week (taught by Brad Geddes from bgTheory) where I learned a cool new technique for this.
Do a search for anything related to your keyword in Google (using the ~ operator) while also using the keyword as a negative term in the search (using the – operator). Then look for any bolded words in the results. These bolded words are what Google considers related. To get even more words, run the search again using all of the words you found as negative keywords.
So for example, if you want to find any words related to “mortgage” use the following search:
When you run this you will notice that the words “finance”, “refinance”, “lending” and “bank” are are bolded. So Google considers these words related to “mortgage”. Now run the search again using the new words as negative keywords, like this:
~mortgage -mortgage -finance -refinance -lending -bank
This results in some new related words: “financial”, “interest” and “corp”. You can keep adding these to the negative keyword list until Google stops finding words.
You now have a new list of words that you might consider as keywords in a PPC campaign or for using as keywords in SEO.
