Time-of-Day Ad Scheduling Based on Vietnam’s Online Activity

In Vietnam’s fast-growing digital market, timing your online ads effectively can significantly impact your ROI. With internet penetration exceeding 75% and over 72 million active social media users in 2025, understanding when your target audience is online is just as critical as what you are advertising. Smart advertisers are now leveraging time-of-day ad scheduling—also known as dayparting—to enhance campaign performance across platforms like Facebook, Google Ads, TikTok, and Zalo.

In this article, we explore Vietnam’s digital behavior trends by time of day and explain how businesses can schedule ads for maximum visibility and engagement.

Why Time-of-Day Matters in Vietnam’s Digital Landscape

Vietnam has one of the most engaged online populations in Southeast Asia. According to DataReportal’s Vietnam Digital 2024 Report, the average Vietnamese user spends over 6.5 hours online daily, including:

2.5 hours on social media
1.5 hours on video content
Time spent on e-commerce, messaging apps, and news platforms

However, digital activity isn’t uniformly distributed throughout the day. Users have clear peak engagement periods, which vary based on demographics, device type, platform, and even location (urban vs. rural).

Key Online Activity Trends by Time of Day

Users typically check news, emails, and weather apps before starting their day.
Facebook and Zalo usage spikes during this period, especially among working professionals and office-goers.
Best ad types: Awareness campaigns, daily deal reminders, breakfast product ads, news-related sponsorships

💡 Tip: Run Zalo Ads or Facebook Boosts targeting working professionals who commute with their phones.
