Frequently Asked Questions

Is TikTok advertising cheaper than Facebook?

Yes, TikTok generally offers lower CPMs ($3.50 average) compared to Facebook ($6.59 average). However, Facebook often delivers lower CPCs for certain campaign types. The "cheaper" platform depends on your specific goals and how you measure cost efficiency.

Which platform has better targeting options?

Facebook currently offers more sophisticated targeting options, including detailed demographics, behaviors, life events, and extensive custom audience capabilities. TikTok's targeting is improving but remains less granular, though its algorithm often finds relevant users effectively without detailed targeting.

Can I run the same ads on both platforms?

Technically yes, but you shouldn't. TikTok requires native, vertical video content that feels organic to the platform. Facebook supports more diverse formats. Repurposed content typically underperforms compared to platform-native creative.

Which platform is better for e-commerce?

It depends on your audience. TikTok with TikTok Shop integration is powerful for products targeting under-35 consumers, especially in beauty, fashion, and lifestyle. For detailed tactics on leveraging TikTok's commerce features, see our TikTok Shop marketing strategy for 2026. Facebook remains stronger for older demographics and offers more mature catalog advertising tools.

How do I track results across both platforms?

Use UTM parameters on all destination URLs, implement both the TikTok Pixel and Meta Pixel, and consider a third-party attribution tool like Triple Whale, Northbeam, or Rockerbox for unified reporting across platforms.
