I just heard of a secret google code that gets google ppc ads for free - just wondering if anybody has heard of that.

There are billion such "secrets" out there and they are all rubbish.
But they do tickle your curiosity uh? That’s what they are "designed" to do.
Anyway, just learn a few google "secrets" then you will be able to search for that ebook on the net, then you can freely download it and read it yourself! lol.

One thing you can do, if your host site allows .php, is to set up a redirect page. This is used by many marketers to mask their affiliate link so it does not get hijacked. You set up your web page as a .php page and set up a blank page with the direct link to the selling site you want the client to click through to. When the customer clicks your link, it will send him or her to your .php page and without the customer even seeing it, he or she will redirect to the business page.

This method can make updating links simpler as well. You don’t get penalized for doing this. One point to be helpful - Google ranks pages higher that are comprised of multiple pages instead of 1-page affiliate ad sites. The mechanics of setting these things up are in the forums and training at my source. They train and you can share your knowledge as well.

Please don’t put up any of those make $1000 a day links. If you’ve actually made money off of google may you please post how you did it?

What your talking about is Google Adsense. Basically Adsense puts ads on your page, based on the content of the page. They then pay you every time someone clicks on an ad. But not all clicks are the same, some for like an ‘insurance’ site is much more than for a ‘computer sales’ site. If you want to earn some cash with google check out
