HUGE TIP HERE: I Have made over 200 adwords accs and none got suspended immidiately only after a couple of months, some ran for a year or so all because of cloaking (my guess as they dont give you a reason why they suspend accs).
1. When you make a new acc dont leave any traces of any previous acc that you have or lost. I mean even change your address, do google maps and find a real address dont just makeup a randm address.
2. Get a new server IP (hosting), new domain, dont make your whois info private just put fake name and details, when your acc goes under review they check and if one of them in the review team feels suspecious of a private whois they just ban.
3. If you can help it use a cheque acc card, not credit card, AVS can be a pain at times even if you get your bank to issue you a new card, you may get "suspended because of suspecious billing info" because your real address is not matching up with the new address you added n your adwords acc., with a cheque card you can use the new address you have on the new adwrds acc, avs wont be an issue here. Stay away from any VCC, they just dnt work PERIOD!!! If you in a country that accepts bank as a way to fund your adwords acc, this is the best as they cant trace you, here in South Africa they use a collections agency to handle their bank transfer clients, so Google cant see where the funds are comming from.
4. Run the acc for a few weeks with dummy ads, act as if you a new client that doesnt know shit about adowrds. I have noticed after a month or so, you dont get the "under review" issue that you get with new accs, you just have to be patient with this, adwords is doing everything in their power to clamp down on spammy ads or missleading advertising.
5. With regards to a VPS, I leant that you might get away with it some times but unfortunately at times when your acc goes under review for the first time when you create from a VPS, the reviews now trace the IP and can see its cmming from a datacenter and hit the ban hammer on you.
6.DNT USE ANALYTICS! Use your own tracking tools, like CPVLABS or prosper!!
7. No I havent tried virtual machine!!
8. USE A CLOAKER!
9. Dont use gmail, use other email providers, theses fuckers trace all that shit!! Try not to surf sites that have you banned adwrds profle whereby they can trce you.
9. Get an MCC Acc and manage many adwords acc, pretend you managing client accs, that way if an acc goes down, its the client who is at fault!!!
