It’s likely that most people have encountered the “Allow Tracking” prompt countless times when using apps. Some click “yes” without a second thought, while others refuse automatically. To understand exactly what happens when you allow tracking, one writer from TechTudo decided to conduct a seven-day experiment on just TikTok and Instagram. What he discovered was a noticeable increase in personalized ads, eerily accurate content suggestions, and clear signs that data flows freely between platforms.
What Changed After Enabling Tracking?
The writer conducted the test on an iPhone, enabling “Allow Tracking” for popular apps and maintaining his usual routine. He frequently searched for topics like baby sleep routines and introduction to solid foods—interests that had become part of his daily life as a new parent. He also added some clothing searches to see how the algorithms would react.
Days 1–2: Ads Start “Talking” Across Apps
In the first couple of days, the change wasn’t dramatic. There was a general increase in the number of ads and content related to his recent searches. The “Explore” section on Instagram began showing more content from the niches he was interested in, and TikTok started displaying more generic ads from online stores. The apps seemed to have noticed his interests, but the suggestions were still broad and not particularly refined.
Days 3–4: Algorithms Begin to Adjust
By the third day, the changes became more noticeable. TikTok began showing videos and ads that clearly reflected searches he had made outside the app, especially around baby sleep and solid food introduction. Some clothing ads started to feel intrusive, as if the app was trying too hard to sell him something. His feed gradually shifted from a mix of content to something that felt more like a storefront.
On Instagram, Reels became “smarter.” The suggestions aligned more closely with his recent interests, and the randomness of the feed decreased. It was as if the algorithm was starting to connect the dots from the data it had collected.
Days 5–7: Extreme Personalization—and Fatigue
In the final days of the experiment, the personalization became aggressive. The same products and categories began appearing repeatedly—classic retargeting. He saw multiple ads for “wrinkle-free” shirts and felt like he was being bombarded with information about baby feeding.
Instagram’s “Explore” page became almost entirely dominated by baby-related content. Topics he had previously shown interest in—like hairstyles, travel, or fashion—disappeared from his feed.
The End of the Week: Results and Reflections
By the end of the seven days, the writer realized that tracking works in stages: first, it increases the volume of relevant content; then, it refines suggestions based on behavior both inside and outside the apps; finally, it intensifies repetition to nudge users toward purchases.
Without planning to, he found himself buying clothes, influenced by the persistent and precise recommendations. He also felt a growing sense of anxiety as the apps began offering “solutions” to problems he hadn’t even considered—special spoons, themed plates, white noise machines, lavender-scented roll-ons, and more. The algorithms had created needs he didn’t know he had.
By the end of the week, he felt the urge to disconnect. The social media experience had shifted from socializing to shopping, with every scroll serving as a reminder of what he “needed” to buy.
Conclusion
The experiment made it clear: allowing tracking gradually transforms the social media experience. It starts with more content related to your interests, then refines those interests using cross-app data, and finally, bombards you with repeated ads to drive purchases. The result is a highly personalized—and increasingly invasive—environment. The feed becomes less about entertainment and more about consumption, influencing choices and even creating new desires. In the end, the writer felt both fascinated and exhausted by the power of the algorithms—and more aware than ever of the trade-offs involved in allowing apps to track him.
