I did my research online and here are results:
Code:
keyword TrafficEst AllInTitle:"keyword"
2 words 2000 176 000
3 words 160 3840
3 words 30 1290
4 words 38 858
3 words 38 6320
3 words 15 1370
3 words 12 827
3 words 21 785
3 words 10 216
4 words 14 136
3 words 25 972
I want to keep my keywords confidential

but i can say that each of my keywords has first "2 word" keyword in it.
I made traffic estimation with Google TrafficEstimatorSandbox.
Now what be my next step, should i do more research on this keywords or start building a site and writing content?
I also appreciate any other suggestions you may have.
