Please answer only if ur creating new google ads account without getting a single suspension because I don't want theories.
You have to have a theory of a strategy. You need to write down all possible parameters that may influence campaigns and suspensions.
You have 2 categories of problems - one problems are optimizations, another are suspensions.
A lot of people showed me their sites throughout the years, their ads. It was obvious for me why they get suspensions.
They use cloaking instead of making real pages. And so on.
Cloaking is so damn easy to detect for contemporary bots.
Campaign Optimization Parameters
- Target Audience: Demographics, interests, behaviors.
- Ad Content: Copy, visuals, call-to-action.
- Ad Placement: Platforms, time of day, geographic locations.

So now, ask yourself. Are you working on those or are you looking for an easy fix like "change age of an account"?
We're born story-tellers, but telling ourselves fantasies about easy business made of "aged accs" is nothing more than a groupthink delusion.
So you can have dropshipping and affiliate marketing ads, as long as you stick to industry standards and niche standards in general. Of course you cannot link directly to offers cause if everyone did so, Google ads ecosystem would collapse. So they don't allow that. They ask you to provide more value and they pay you for that.

Novice people who have been doing for less than a decade always think they're smarter than those who did for 30 - 40 - 50 years.
Guess why... ego stuff? Too much emotions? Not enough work on inner-self? Thinking money comes from external solutions and not internal value production?
