regarding google adwords

google separates its adwords into two sections

search terms:- u chose a keyword or keywords that people may search for

content site terms:- u choose keyword or keywords that appear on pages in the google network (affiliates).

basically u create an advert and it displays on the basis of the above two scenarios...

i read that putting the keywords in [ ] brackets is better because you get only clicks from the exact word you want, and your click thru rate.. and hence ranking is higher..

however, does anybody know a great deal more then this on adwords.. i have googled for tips but they are all very straightforward.

anyone know something i should know?

Adword’s increases traffic and also increase the operating cost altogether, in fact it might increase the traffic but you can’t predict the sales in advance. I would suggest to monitor it well and to calculate risk in advance before you increase the limit.
