To optimize the reach of your posts for a U.S. audience while considering a UTC+0 time zone, you should aim to publish during peak engagement times in the United States. Here are some recommended time slots based on common engagement patterns:
Early Morning (8 AM - 10 AM EST): This corresponds to 1 PM - 3 PM UTC. Many people check their social media and blogs in the morning before work or school.
Lunchtime (12 PM - 2 PM EST): This corresponds to 5 PM - 7 PM UTC. Posting around lunchtime can capture audiences who are taking breaks and browsing online.
Evening (6 PM - 9 PM EST): This corresponds to 11 PM - 2 AM UTC. Many people are active on social media after work, making it a good time for engagement.
Considering your current time of 5:20 AM UTC, the best time to publish would be after 1 PM UTC, aiming for those early afternoon or evening slots in the U.S.
