Google is requesting a Certificate required in South Korea, so I might not be able to obtain this.
In that case, you will have to run an effectively cloaked campaign.
Whatever that is possible upto now, which can be openly shared about running a cloaked campaign in Google Ads (including cloaked gambling / casino campaign in Google Ads), has ALREADY been shared in various threads of the BHW Google Ads section. There is absolutely nothing about it which can be further openly shared. So, you need to serve yourself by going through various / as many threads as possible in the BHW Google Ads section, to get hints, tips, suggestions, etc.
And, remember, that no two cloaked campaigns are exactly the same, just as no two safe pages are exactly the same, just as no two money pages are exactly the same, just like not all gambling / casino offers being run in Google Ads are not the same.
Therefore, no one can simply popup out of the blue and tell you "use these keywords", "have your safe page exactly like this or like that", "have your money page exactly like this or like that".
Even within the same niche (example : gambling / casino), it is never "one size fits all" and infact must never be, otherwise it would result in disasters.
And, even assuming that someone pops up out the blue and gives you such exact and precise details, it would be nothing but a disaster for you. Why ? Because, those keywords may attract a different gambling audience and not the gambling audience pertaining to your exact gambling offer, so you will end up wasting your ad budget(s).
Many members are happy that BHW does have an option to Hire A Freelancer in order to get help with things related to digital marketing. Some people burn the midnight oil, do a lot of research and experiments and get to learn on their own and get their stuff moving. But, it is not practical for everyone to do so. And, that is why some people Hire A Freelancer, especially when certain tasks or projects do not come for free and also especially when a certain task or project is not "one size fits all", thereby requiring in-depth research based on the specific output that is desired (example of this, is keywords research pertaining to running clocked / blackhat campaigns in Google Ads).
Again, we must bear in mind, that running cloaked blackhat campaigns in Google Ads, is something highly profitable. So, those who are the REAL experts in this, run campaigns on their own, for themselves > such experts make more money this way, than coaching others or running cloaked blackhat campaigns for others. In other words, even if you may think of Hire A Freelancer, think twice. Recently there has been a spike in "boogy woogy", "scoopy doopy" as far as Google Ads is concerned.
So, you would rather go through as many threads as possible in BHW Google Ads section, make a note of important points and then embark on the trip on your own. Yes, there will be a learning curve and that is how the experts became the experts that they are.
However, just like a few other members also have mentioned a few times, success in Google Ads is ONLY & ONLY about creativity and NOTHING ELSE, especially success in cloaked blackhat campaigns.
