Have you felt like someone is looking over your shoulder when you access the internet? Tracking your every move on social media and sending you ads about things you were thinking of buying? If so, you are a victim of targeted advertisements.

Advertisements on the internet are like a boomerang; you look for a book to read on Amazon, and it comes back to you as an ad in your feed, on Facebook or Instagram. Tech giants like Facebook and Google, among several other big data companies, are monitoring your every move on the internet, but you might be thinking, why does a company like Google want to track you? Well, simply because you have data to give, which can be used by advertisers on these platforms, and is eventually used to generate more revenue.

Targetted ads are like an annoying stalker that will keep freaking you out even if you shift devices. To get your data, companies use tracking technologies like third-party cookies and tracking pixels. Once they have secured your data, they connect it to unique identifiers creating your online profiles. These profiles can be used to identify you over the internet across different devices using deterministic/probabilistic matching. These profiles are then analysed using machine learning algorithms to understand what makes you tick? What you like? What opinions you have and how companies can influence you. These methods are so advance that they can sway elections.

All this data collection is not restricted to your web browsers. Apps installed on your phone collect all kinds of data and send it to Facebook for analysis to send you targeted ads. The Facebook SDK at the heart of many popular apps like Spotify, ticktock and Venmo is used to collect data from different apps which makes targetted ads more specific.

Looking at these banners of ads which are tracking your every move to give you an “enhanced user experience” can get on your nerves. Although there is no way to keep these prying eyes at bay and to stop them from collecting your data completely. You can follow a few steps to reduce the number of targeted ads you see.

Installing ad blockers like Adblock or Ghostery can reduce the number of ads you see on a website. It also blocks trackers which are used by a lot of sites to reduce targetted ads.

New data privacy laws like the GDPR are a step in the right direction, but people need to understand that till the time we think we have nothing to hide and don’t talk about privacy laws in our countries, nothing is stopping tech giants like Facebook and Google from harnessing your data for profits.

Due to the bulk collection technologies used by these tech giants, they have a large number of data points to identify each person and understand their behaviour using machine learning and advance analytics. So by giving them our data, we are providing them with a gateway to our thoughts, which is scary.
