Google offers many services like search, email, maps, and cloud storage – and they are the biggest platform online for advertising. LOTS of advertising. From YouTube to Search Google maintains the world’s largest advertising ecosystem and they rely heavily on data they collect from you to maximize the effectiveness of it. Nearly all of the services they provide rely on collecting something about you to build out your profile and create a fuller picture of you. This information helps Google make their services work better for you, and also allows them to collect top dollar from their advertising partners.
So what info does Google collect? Well, Google collects basically whatever they can from you. Some of the information is what you provide to them (like when you setup an account or answer questions periodically). But the real genius behind Google’s data collection is what goes on behind the scenes. They have access to where you go, what you watch, and which ads you click on. Think about the products they provide that you might be using right now – including Android, Chrome, Gmail, etc. All the actions you take on their platforms are potentially data that they are collecting about you. They say they use this information to improve your experience and make it more personal.
Since the early days of Google people have voiced concern over their privacy, and Google has always been committed to protecting their users and securing their data. The good news is that Google does give you some controls over what data you allow them to collect so it’s important to understand that process if you want to limit your exposure.
