The right advertising platform is a tricky choice for ecommerce businesses. TikTok has exploded over the past few years, and Meta has its established dominance in the social space. The question isn’t whether to advertise on social media—it’s where to put your money for the best return.

In 2025, both platforms have advantages, but how well they perform depends on your audience, products, and goals. We explore both TikTok and Meta ads to help you decide which platform deserves your advertising budget.

Social Commerce in 2025

Social media advertising moves fast. TikTok has nearly 1.6 billion monthly active users as of February 2025. But Meta is still the world’s largest social network, currently boasting over 3 billion monthly active users across Facebook and Instagram.

The way people shop has also changed dramatically, particularly for TikTok users. Now, those users are known to buy products and services they find on the platform, rather than only using it for entertainment. 

TikTok Ads as a Creative Powerhouse

The ROAS Reality Check

TikTok’s median ROAS is lower at 1.4× but can be up to 2.25× when brands use the “value-based” optimization.

TikTok may also be better at getting those new customers rather than just retargeting existing ones.

TikTok’s Strengths

• Creativity First: TikTok shines with its creative, trend-driven approach, perfect for Gen Z. The platform rewards authentic, entertaining content over polished ads.
• Lower Entry Costs: TikTok’s average CPC costs less than Meta, making it easier for small brands to use.
• Quick Learning: TikTok learns about its users fast. It understands their behavior and interests based on video engagement alone and delivers relevant content rapidly.

TikTok’s Challenges

• Creative Demands: Campaigns need constant maintenance (e.g., launching new video ads) to keep performance consistent.
• Platform Maturity: It can be difficult to drive traffic to TikTok Shop or to convert shoppers. The platform is still developing its ecommerce infrastructure.

Meta Ads: The Conversion Champion

Cost Considerations

Meta’s costs reflect its premium positioning. Their CPC saw an increase of 18.95%, moving from $1.40 in 2024 to $1.67 in 2025. While more expensive than TikTok, this can translate to higher-quality traffic.

Meta’s Competitive Advantages

Targeting Precision: They are the leader in targeting capabilities, allowing advertisers to reach their exact audience.

Proven Tools: Meta’s advanced tools, like dynamic product ads and the Facebook Pixel, help businesses track conversions and measure ROI more effectively.

Consistent Performance: Meta is more consistent from week to week. It also learns potential purchase behavior faster and can generate better CAC and ROAS. 

Meta’s Limitations

Higher Costs: Meta’s legacy status and competition drive up costs.

Ad Fatigue: Standing out in a sea of content needs lots of creative investment and testing.

Platform Comparison

Conversion Rates

Meta is known to have a greater ability to convert interested viewers into customers.

Cost Efficiency

TikTok wins on cost efficiency, but Meta’s higher costs often translate to better conversion quality.

ROAS Performance

• TikTok: 1.41× overall (2.25× with optimization)
• Meta: 2.19× overall (3.61× for retargeting)

Meta consistently delivers higher returns, especially for retargeting campaigns.

When to Choose TikTok vs. Meta

Choose TikTok when:

• Your audience is young
• You’re building brand awareness
• You have creative resources
• Testing new markets

Meta is your best choice when:

• You need reliable conversions
• You’re targeting broader demographics
• You have established products
• Running retargeting campaigns

The Best Strategy? Use Both Platforms

Play to the strengths of each platform. Use TikTok to grab attention and Meta to close the deal.

• Top-of-Funnel (TikTok): Use TikTok’s popularity and lower costs to show your brand to new audiences. Give them entertaining, educational content.
• Middle and Bottom Funnel (Meta): Retarget TikTok traffic through Meta’s targeting system. 
• Cross-Platform Optimization: Use TikTok for awareness. Push warm leads to Meta for retargeting.

Making Your Decision

Budget: If you’re working with limited funds, start with TikTok, then scale on Meta.

Product Type: Lifestyle products often do better on TikTok; practical or higher consideration purchases usually convert better on Meta.

Resources: TikTok needs more creative energy. Meta calls for stronger analysis skills.

Timeline: Meta’s conversion often shows faster profitability. The virality of TikTok gives it the potential to build long-term brand awareness.

Wrapping Up

Both TikTok and Meta ads have different purposes in your marketing funnel. Use TikTok’s creative, youthful energy to get that attention. Use Meta’s great conversion to drive sales. 

Don’t get caught up in choosing sides. Test both platforms, adapt quickly, and keep continuously improving on your ads.
