is pretty easy. They claim to check every ad but this is just not the case.
If you have an existing ad words account that has been live for a while, you can just set up and add along the following lines
Bid against the word casinos
Have add copy as – Play Now Multiple Games available – Huge first time play bonuses – then display url getyourbonus.com which links to what every casino you want.
This works but is a very short lived strategy, they will ultimately find this ad and will go as far as banning you from adwords. If you use it for your site do you want to run the risk of annoying Goog?
Its not the easiest way, but for a long term plan, SEO, good site design and a good linking strategy will be your biggest help
