By my logic percent is not enough to use only the keywords in one ad
I began to think the simplest way. What attracted to me, what would attract me to become interested in, what would I be kept to read or look at the offer. I made a longer version and started with advertising, and follow the effect of the day I add text or subtracted. But the initial goal is not giving up I always have in front of me, "what would be most attracted me."
