In the frantic world of US online shopping, timing isn’t just crucial; it’s essential. If you’re putting up social media or running ads on the internet and you’re not paying attention to the time of day when your audience is engaged, then you’ve left a lot of cash on the table. No matter if you’re a veteran online retailer or you’re just looking to expand your online store, knowing the most effective times to interact with your customers will improve conversion rates, boost the ROI, and build an even stronger brand image.

Best Times to Run Ads

In this guide from EcomnDev.com, we’ll discover the most effective times to run ads and posts via social media platforms such as Facebook, Instagram, TikTok, and Google. In addition, we’ll explain the top brands in e-commerce, creating their ads to perfection, and how you can achieve the same results.

Why Timing Matters in E-commerce Advertising

Effective e-commerce marketing relies on reaching the right customers at the right time. According to Statista, over 80 percent of Americans purchase online regularly, and a majority are affected by social media and paid ads. However, consumers aren’t always online. Publishing content or running ads in the off-hours can result in fewer views, less engagement, and lost sales.

Top E-commerce Goals That Timing Impacts:

  • Rate of click-through (CTR)
  • Rate of conversion (CR)
  • Cost-per-click (CPC)
  • Return on ad spend (ROAS)
  • Comments and social shares
  • Click rates
