Yeah, I learned a lesson today. I've been building sites and targeting whole wrong keywords and key phrases. Lot and lot of working hours almost for nothing because I didn't realize that when doing keyword research with Adwords Keyword Tool you MUST SET THE MATCH TYPE: EXACT. Otherwise it's BROAD which is very very misleading. For the keyphrase I was targeting my site to I went from 165,000 searches to 91 after changing match type from BROAD to EXACT.. No wonder why I didn't get any traffic..

Another lesson learned in a hard way..
