I am about to setup the PPC-Campaign for my first product.
I did a reverse-ASIN lookup on my top 3 competitors and pulled all the Keywords which they rank at position 10 or better. Now I got a list of about 250 highly relevant Keywords.
Should I put all of them into a manual-exact Campaign? Since I know that my competitors are generating most of their sales over these exact keywords, it should not be necessary to use phrase or even broad, right?
I appreciate any input.
