I can't stress enough that tracking your keywords is really important. If you just started doing PPC, you must understand that NOT tracking your keywords literally means wasting your money. I did this in the beginning and every campaign I put up was a flop until I started tracking my keywords. Yes tracking keywords involves work. But if you don't put the extra effort to set up your campaigns properly then how do you expect to make any money? Fortunately, tracking keywords is not that hard. You just need to set it up once and you're done. There are two ways I use to track keywords. Using adword pixel code and writing small PHP code on my landing pages. I have discussed both ways here in more depth. http://niche-affiliate-marketing.com/affiliate-marketing/tracking-your-keywords-for-ultimate-profit/
