I got very dissapointed to notice what broad match does. And yes, if you check your reports you'll find yourself paying for clicks in "similar" terms highly deceptive. As a result I decided to follow some experts recommendations and avoid Broad to focus on more speficif terms using phrase and exact.
Result this far. Almost nule impressions, very few clicks.
So seems like the chicken and the egg, one coan't be without the other.
If I go for broad: there are some keyphrases with 100% competition, very high prices, and those obvious ones are the ones bringing clicks.
I get ride of those, I lower costs but have nothing to do since even with some 100 keyphrases per ad group and some 4 adgroups per campaign I get > 10 clicks daily.
So what's the story here?
