I ran a 5-day experiment to see how fast Google reshapes your ad profile
- nanobuilds 6mo agoThree fresh Google accounts on different US residential proxies. Two browsed with specific personas (fisherman, fitness). The third did nothing for five days. Google was more aggressive than I expected. 17 new ad interests from a single session. By Day 1 it was already removing interests and replacing them. Not adding to your profile. Rewriting it. The control didn't move once in five days. I built a Mac app (MirrorMask) that does this against your real profiles. Happy to answer questions about the methodology.
