Have you ever wondered what people search for in place of the keywords you are already buying in PPC or optimizing for in SEO? Wouldn't it be cool if Google would give you a search "thesaurus"? They actually do, it's a very cool tool call the Wonder Wheel. Here is how it works:
1. Bring up the classic google search page and make sure that Instant Search is off. (for some reason Google thinks we don't need wonder wheel if we are instant searching)
2. Search on a keyword or phrase that use commonly use for your target audience. One the result page you will see the option for the wonder wheel on the left column.
3. Click on the wonder wheel and you will automatically see a spoked wheel representation of all the other phrases people search on when they also search for your keyword/phrase.
Pretty cool huh? For me this visual representation of the phrases is much better than suggested keywords in PPC.
