"So, how much traffic did you get from <insert source here>?" "Ummm, not sure..."
Well, how much traffic did you get to your site?" "Ummm, not sure..."
"OK, how about sales? Did your website produce any sales?" (You guessed it!) "Ummm, not sure..."
Sound familiar? Heard those questions before? The crux of it is what you did based on those questions. Did you just soldier on, put your head in the sand like an ostrich, or actually take a long hard look at your whole website and how you track campaigns?
Why sites don't perform
1. No one knows they're there! Yes. I know that sounds simplistic, but, if you're on page 3 or worse you are, to all intents and purposes, invisible.
2. Bad navigation on site. I see it all the time, even on professionally designed sites. You can't find anything; important stuff hidden behind 2-3 mouse clicks.
3. Lots of flash. Yep, Google supposedly can read content in flash, or is close to. But do you want to alienate 10's of millions of Apple mobile users?
4. Poorly optimized graphics. You can get browsers to re-size that 4Mb 3000px x 1800px image if you're too lazy
