We’ll cover CPM rates, engagement costs, conversion values, and cost-efficiency trends by industry and ad format.
By the end, you’ll know which platform is the best fit for your product category and precisely how much you should be spending to achieve impressive returns on investment (ROI).
Understanding Ad Costs and Metrics
Before jumping into platform comparisons, it’s essential to decode the key cost metrics used in advertising.
CPM (Cost Per Thousand Impressions)
CPM measures the cost to have your ad shown 1,000 times. It’s a vital metric for brand awareness campaigns aiming to reach wide audiences.
CPC (Cost Per Click)
CPC measures how much you pay for each click on your ad. This is a key metric for driving traffic and measuring interest levels.
CPA (Cost Per Acquisition/Action)
CPA tracks the cost incurred when a user completes a specific action, such as signing up or making a purchase. It’s essential for conversion-focused campaigns and ROI evaluation.
CTR (Click-Through Rate)
CTR shows how often people who see your ad actually click on it. It helps measure the effectiveness of your ad creative and targeting.
Now that we’ve defined these terms, let’s examine how Facebook, TikTok, and Pinterest stack up on these metrics.
Platform 1: Facebook Ads
Facebook remains one of the most robust advertising platforms, largely due to its vast audience base and sophisticated targeting tools.
Key Metrics for Facebook:
- Average CPM: $8.21
- Average CPC: $0.97
- Average CPA (eCommerce): $18.68
- CTR Average Across Industries: 1.11%
Performance Insights
Facebook’s CPM of $8.21 makes it relatively affordable for brand-building campaigns, especially when compared to other major platforms. With billions of monthly active users, Facebook provides advertisers a huge reach and excellent targeting tools, like Lookalike Audiences and interest-based filters.
For industries like eCommerce, Facebook delivers high ROI, particularly for video ad formats. Data from spy tools shows that short, square-shaped videos achieve a CTR 30% higher than static image ads.
However, competition in sectors like fashion and wellness can drive up CPC rates as many direct-to-consumer brands compete for the same audience.
Best Use Cases
- Ideal For digital-first brands looking to drive conversions, especially in eCommerce, tech, and wellness.
- Ad Formats That Work:
- Carousel ads for showcasing product collections
- Video ads for storytelling and higher engagement
- Lead generation ads for B2B and professional services
Platform 2: TikTok Ads
TikTok’s meteoric rise has made it a favorite among brands targeting Gen Z and millennials. With its short-form video focus, TikTok reshapes how younger audiences interact with ads.
Key Metrics for TikTok:
- Average CPM: $10.00
- Average CPC: $1.53
- Average CPA for Performance Campaigns: $19.10
- CTR Average for Top-Tier Content Creators’ Ads: 1.41%
Performance Insights
TikTok has the highest CPM of the three platforms, but its audience engagement levels justify the cost. Users actively interact with ads that feel integrated into the platform’s content style—a phenomenon known as native advertising. Best Ads Spy tools highlight the immense popularity of “challenge campaigns,” where brands create hashtag-based video trends.
While CPC is slightly higher than Facebook’s, TikTok compensates with its effectiveness for brands in niches like fashion, beauty, fitness, and entertainment. TikTok’s CPA for performance campaigns skews toward being slightly more expensive than Facebook, but its user engagement metrics can lead to higher ROI.
Best Use Cases
- Ideal For brands targeting younger demographics interested in lifestyle, fashion, and personal expression.
- Ad Formats That Work:
- TikTok Spark Ads (amplify user-generated videos for credibility)
- Full-screen short videos for maximum focus
- Partnering with influencers for creative collaborations
Platform 3: Pinterest Ads
Pinterest is where users go to find ideas, from recipes to home décor. Its audience is built around intent-driven discovery, making it a hidden gem for certain industries.
Key Metrics for Pinterest:
- Average CPM: $5.00
- Average CPC: $1.50
- Average CPA for Retail Campaigns: $30.00
- CTR Average for Pins: 0.85%
Performance Insights
Pinterest offers the lowest CPM of the three platforms at $5.00, making it an excellent choice for campaigns focused on visibility. However, Pinterest may struggle to match Facebook or TikTok on driving immediate website visits, as its CTR tends to be slightly lower. But for industries like home décor, weddings, and food, where discovery is key, Pinterest ads perform exceptionally well.
Pins function as evergreen content, meaning they continue to drive traffic over time without added spending. Spy tools show that vertical visuals (2×3 aspect ratio) perform the best in boosting CTR.
Pinterest has a higher CPA for retail campaigns due to its uniquely intent-driven nature. However, if you’re marketing a high-value product or service, Pinterest can pay off in the long run.
Best Use Cases
- Ideal For brands in retail, home décor, event planning, and food industries.
- Ad Formats That Work:
- Promoted Pins for amplifying branded content
- Video Pins for DIY and tutorial-style content
- Shopping ads for retail brands looking to connect with consumers ready to buy
Cost-Efficiency Patterns by Industry
Different industries see distinct trends in cost efficiency across these platforms.
- Fashion and Beauty: TikTok excels with its hyper-engagement for younger demographics, but Facebook also performs well in driving purchases.
- ECommerce: Facebook remains the champion for broad-target eCommerce advertising with lower CPAs than TikTok.
- Home Décor and DIY: Pinterest’s discovery-oriented platform makes it a high-value choice over both TikTok and Facebook.
- Corporate and B2B: Facebook outshines others for lead generation in professional industries.
Choosing the Right Platform for Your Product
When deciding which ad platform to allocate your budget to, consider the following:
- Target Audience: Match the platform to your audience demographics. For example, Gen Z thrives on TikTok, while Pinterest resonates with home and lifestyle enthusiasts.
- Campaign Goals: Define whether your goal is brand awareness, conversions, or lead generation. Each platform offers different strengths.
- Ad Format Adaptability: TikTok videos demand creative storytelling, while Pinterest leans on discoverability and Facebook focuses on conversions.
