What is the main purpose of a company building a profile based on users' browsing history?

Building a profile based on users' browsing history primarily serves the purpose of creating more targeted advertisements. By analyzing users' online behaviors and preferences, companies can gain insights into what specific products or services are likely to interest those users. This allows them to tailor their advertising strategies to be more relevant and appealing, which can lead to higher engagement rates and increased conversion rates.

Targeted advertising is more efficient than traditional broad-spectrum advertising because it ensures that individuals see ads that align with their interests and needs. This personalized approach not only benefits the company by potentially increasing sales but also improves the user experience by showing them ads that are more likely to resonate with them.

While enhancing user privacy and limiting website access might seem advantageous from a user-centric perspective, they do not align with the primary commercial objectives driving the collection and analysis of user data. Reducing internet speeds is not relevant to the context of user data profiling, as this is more concerned with the performance of the internet rather than the marketing or advertising strategies employed by businesses.
