As an expert SEO copywriter, I can confidently say that the best times to schedule Facebook ads depend on your target audience. If your target audience is mostly made up of working professionals, then it's best to schedule your ads during weekdays, particularly during lunch breaks or after-work hours. On the other hand, if your target audience is composed of stay-at-home parents or students, then weekends and evenings might be more effective. It's also important to consider the time zone of your target audience. If they are located in different parts of the world, you may need to adjust your ad schedule accordingly. Additionally, it's crucial to monitor the performance of your ads and adjust your schedule based on the data you gather. By doing so, you can ensure that your ads are being seen by the right people at the right time.
