Ktorá z nasledujúcich možností opisuje experimentačný nástroj od Googlu?

The Google Ads Experiments tool allows advertisers to test changes to their campaigns, such as different creatives, bidding strategies, audiences, or other variables, to measure their effectiveness before applying them broadly. This helps optimize campaign performance based on data-driven insights. The first incorrect option is wrong because Google Ads Experiments does not involve additional fees; it's a feature within the platform. The second option is incorrect because it describes a simulated environment, whereas Experiments run tests with real traffic. The third option is incorrect because Experiments don't necessarily show two versions to all users; they split traffic to compare performance, and the goal is performance, not just preference.
