I have 100 keywords and held in my Justin bieber LI campaign and I am the #1 bidder for all of them.
Yet i am not getting a single click.
My lander is approved but I get no traffic.
Why??
And these are high traffic keywords.
I take it you are also bidding on any shortened versions of the keywords? like beiber, beibe, etc. I assume you are since you're apart of this forum lol just asking
Yes I am 
And I have a positive balance, I haven't reached my daily max spend
So what is happening??
Email/call traffic source.
Go to bed and check stats tomorrow.
100 is probably not enough data. And your lander could be ineffective - chances are probably will be a low CTR lander.
did you double ck all your links and tracking?
esp what you gave LI?
also LI is very slow to update...if you see your balance going down....your getting clicks... balance is real time.....click tracking isn't
bid #1 does not mean the target is a high traffic or have any traffic, you need to kiss some potential froggies in order to find the prince ( if you picky and assume you know your demo quite well ) else you have to use the shotgun approach, which is kiss any frog (target) you can find.
in this game, number tell you the truth, not the other round, which you assume it will work... the more assumption you make, the more further from the profitable campaign, you should model some successful newbie here, get your $1 profit campaign going first.
LI is very slow to update, check your 202 to see if you're actually getting clicks.
Sometimes there can be a half day delay between camps getting approved in LI and traffic starting to flow. Make sure everything is setup correctly before you go to sleep, set the $5 budget to limit your risk, and then go to sleep.
