When Priya searched for “lightweight hiking boots” on her phone, she clicked the first result — a colorful ad from an outdoor store. She noticed the link started with https://www.googleadservices.com/pagead/... before jumping to the store’s website.

“Not a virus,” she told her friend. “Just the invisible accountant of the free internet.” googleadservices.com is Google’s ad click auditor — not a spy, not a hacker. You can block it if you value privacy above all. But if you enjoy free content and relevant ads, it’s a fair trade.

Later, she saw a privacy setting in her Google Account: “Ad personalization.” She turned it off — but she kept seeing ads, just less relevant ones. And googleadservices.com kept working silently, measuring clicks without storing her personal data.
