My personal opinion stay away from pay-per-click it will eat your money and you will get very little in return.
Here has been my experience with pay-per-click, though many years ago this was my experience.
First in order to even get listed on the first 10 pages you need to raise your per click amount. And being on a low budget it is almost impossible to compete and maintain that payout level. There are companies that spend hundreds of dollars per click (yes per click) to maintain the top 2-3 page listing for the best words. And if you are only spending pennies per word, then your just giving your pennies away.
Also there are scripts that exist to "bust your bank" to keep you from even competing. They register a click to your site again and again via different proxies and even domains to try to register a qualified and approved click. And when they do, you pay for it. They do this because they dont want you in the game and so they try to "bust your bank" every time you make the attempt to compete.
I never knew where the scripts came from or who was behind it. However if you remember google was sued for overcharging pay per click customers years ago in a class action suit, and i joined that suit and i got a check back for about $25.00, this was after i spent over $300 in pay-per-click. That is 8% of the clicks they agreed were back clicks. This is what they settled for not what was actual.
So at that rate it would have been $80 out of every $1000 was BS and i would have been paying that much for nothing.
Your money is better spent with the old fashioned due dilligence and other ways of getting the name out. Stick with tangible items that you can see what you get when you pay for it. Not some invisible "click" or "word" brokerage platform.
When you are successfull and have money to burn that you will never miss then jump into PPC. Thats my experience.
