I use msn, for adcenter to affiliate arbitrage. They are bitchy about everything, but I get much better conversion rates.
You got it messed up. I was talking about the way you earn money, not spend money to buy traffic...Adsense is fine, but I got banned. Try Yahoo ads.
I guess the problem is with your bid price. 8 cents is low. If your ads dont show, the problem is not that your daily budget is low, its that your bid price is low.
Ill try to explain.
You bid on credit, and suppose the competition bids 1$ for it
If you bid 8 cents, and there are like 7-8 competitors, your ad will almost never show. You will need to bid at least 80 cents to get some impressions.
Now, if your Quality score (relevancy of the landing page to the keyword) is good, the bid price you need to stay on the same spot is lowered, say 75 cents. Also, if your Click Through Rate is good (clicks divided by impressions), then you also pay less, 65 cents.
Daily budget has nothing to do with all of the above.
I guess what you havent understood yet is that you need higher bids, not higher budget. Higher budget allows you to get more clicks(and spend more)
Higher bids allow your ad to show higher up in the queue, thus generating clicks.
I used the ad I posted above, with a huge keyword list and bids at 23 cents. Because everyone clicked on the ad (since it calls out CLICKME) I got a great CTR. Combined with the relevancy of my landing pages, my QS allowed me to bid 10 cents, then 5 cents, and I managed to get it to 1 cent. 5 euro, 500 visitors exactly PER DAY.
The problem was to monetize the traffic, since 8 year olds dont buy from amazon
But I found a way.
You need to do some more studying before you throw in 600$ per day on an experiment. Get a 5$ budget, turn it into a 7$ income. Learn the tricks, and then go for 30$ to 60$, and 100$ to 200$.
EDIT* for all the previous posters. The guy's problem is that he gets no clicks on his adwords ads, not on his adsense blocks. Hey aveligand, you do have blocks, not banners, right?
