You're doing it wrong. You're only gonna get bottled up blog advice posting questions...
You need to get your head out of your ass and start experimenting more with other traffic sources and stop depending on organic shit...
Well...ok. Didn't mean to offend you with my request for help, but since you've chimed in, do you have any thing that might help that isn't "bottled up blog advice". You must have some PPC skills if you're so quick to come in and say that I'm not doing it correctly.
As I see it, you're either buying traffic or you're getting it organically. The latter takes a completely different skill set and patience level than just entering a credit card and starting a PPC campaign. I realize that PPC isn't easy, and I'm trying to figure that game out, but bashing how I make a living for no other reason than to sound cool doesn't do anyone any good. If you have any real suggestions as to what I might focus on to be more successful with PPC, then I'm all ears.
Back to business here....
Keywords - Now that I'm seeing what keywords are getting some good action and CTR, I want to expand those, but I'm having a tough time coming up with alternate versions. Also, I've been running everything on broad match anyway, so if I add the word "buy" to some of my keyword phrases, wouldn't they have been found anyway without the additional word since I was doing broad matching. Is this wrong? Should I run this type of thing on exact match to get more targeted? Also, negative keywords, what's a good way to put together good negative keywords lists?
