Do crowd search with BRAND KEYWORDS only when your site is above page 4.
Once you are under page 4, start the keyword Crowd search.
Once you see the rankings are improving, do BOTH keyword and brand keywords together.
Eg: assuming your company name is aaaplumbing
Send 5 brand searches a day "aaaplumbing"
send 5 keyword searches a day "plumbers in Phoenix"
That way, you get CS traffic from both BRAND keyword and Money keyword.
