damn I can't be giving away all my secrets..haha
Just a point on what I mean on behavioral research. Take the word for instance
car:
1) I type car into adwords
2) I click on filter and type in "cars"
3) I click "negative" under match type. Why is this important? Because this will give you an insight to to co-occurrence. In other words you'll get some understanding of what kind of words are being use "along side" your main keyword phrase. You will also see modifiers. Now let me further explain. For cars, here are some of the words:
-hire (an adjective or a verb. people are looking to "do" something with cars or are looking for a type of car)
-rental (an adjective, people are looking for a certain kind of car)
-rent (a verb, i.e. an action, what people are looking to do)
-luxury (a descriptive word, an adjective, a certain kind of car. note, if I put all the adjectives together and checked out their cpc, I could see which descriptive words meant more to the market..."luxury" is worth more than "cheap")
-cheap
-used
-carhire
-companies
-hertz (a brand name)
-insurance (a noun, also can be an adjective, an adjacent market term. by market I mean there are at least 10m competing pages)
-rent a (another great descriptive term. try typing in "rent a" to see what people want to rent. Also try "rent an". you want to us "a" and "an" because with "a" you'll find topics that start with a consonant and with "an" vowels" - ex. "rent an airplane" "rent a trailer"
-pictures
-cheapest
-sale
-rentals
-dealer
-dealership
-dealers
-rental cars
-parts
-free
-ireland (place. noun. people are doing geography/location related searches)
-europe (same)
-dublin (same...also if this is a us search it also says people are looking at cars abroad)
-portugal
-spain
-malaga
-italy
-airport
-cheap rental
-water
The gist of what I was saying is that you don't just want to see "what" people are searching for you want to "see + understand" "why" they are searching for it...
Hope it help.... (ps, typed fast excuse any typos)
pps
also try question words to see what people what answers to:
-who
-what
-when
-where
-how
-why
-which
Also, make sure to use your "brain filter" as sometimes you'll get things that pop up such as tv shows, movies, lyrics, etc. this is where you have to put your thinking cap on...
Just try typing in 'end goal' what people really want. You'll be amazed time and time again people use the engines like they are talking to an oracle. try typing in the word "security" or "love" or "safety" people are looking for products, services, etc. to get these end goals
