Beyond the Basics: Looking Past Likes and Comments

While likes and comments are essential engagement indicators, they only tell part of the story regarding carousel posts. You need to dig deeper into the analytics to truly understand your carousels' performance.

Swipe-Through Rate (STR)

What it is: The percentage of viewers swipe through all slides in your carousel.

Why it matters: A high STR indicates your content is compelling enough to keep users engaged throughout the carousel.

How to calculate: (Number of users who viewed the last slide / Number of users who viewed the first slide) x 100

Benchmark: Aim for an STR of 70-80%. If your rate is lower, consider:

  • Making your first slide more enticing
  • Ensuring each slide flows logically to the next
  • Keeping your content concise and visually appealing

Slide-by-Slide Engagement

What it is: The engagement rate for each slide in your carousel.

Why it matters: This metric helps you understand which parts of your carousel resonate most with your audience.

How to analyze: Look for:

  • Drops in engagement on specific slides
  • Slides that receive more interactions (likes, comments)
  • Patterns in content types that perform well

Pro tip: Use this data to inform the structure of future carousels. Lead with your most vital content types and refine or eliminate underperforming elements.


What it is: The number of users who save your carousel post.

Why it matters: Saves indicate that users find your content valuable enough to revisit later.

Interpretation: A high number of saves suggests your content is:

  • Informative
  • Useful for future reference
  • Resonating deeply with your audience

Action item: Create more carousel content that mirrors the style and substance of your most-saved posts.


What it is: The number of times users share your carousel.

Why it matters: Shares expand your reach and indicate that users find your content worth spreading.

Boosting shares: To increase shares:

  • Create carousel content that provides unique value
  • Include a call-to-action encouraging shares
  • Ensure your content is easily shareable and relevant to a broad audience

Click-Through Rate (CTR)

What it is: The percentage of viewers who click on a link in your carousel (if applicable).

Why it matters: A high CTR indicates that your carousel effectively drives traffic to your desired destination.

How to calculate: (Number of clicks / Number of impressions) x 100

Improving CTR:

  • Place your CTA strategically (test different slide positions)
  • Use compelling copy to encourage clicks
  • Ensure your link destination delivers on the carousel's promise

Carousel Completion Rate

What it is: The percentage of viewers interacting with your carousel until the end (last slide or CTA).

Why it matters: This metric shows how effectively your carousel maintains interest throughout.

Calculation: (Number of users who reached the last slide or CTA / Total number of users who viewed the carousel) x 100

Optimization tips:

  • Keep your carousel concise (5-7 slides often perform best)
  • Use a storytelling approach to maintain interest
  • End with a strong CTA or compelling conclusion

Setting Benchmarks for Your Carousel Content

To truly gauge the success of your carousels, it's crucial to establish benchmarks. Here's how:

  • Analyze historical data: Look at the performance of your past carousels to set initial benchmarks.
  • Compare to industry standards: Research average performance metrics in your industry.
  • Set progressive goals: Start with achievable targets and gradually increase them as you optimize your strategy.
  • Regularly review and adjust: Reassess your benchmarks quarterly to ensure they remain challenging yet attainable.

Putting It All Together: A Holistic Approach to Carousel Analytics

While each metric provides valuable insights, the true power lies in analyzing them collectively. Here's a framework for a comprehensive analysis:

  • Start with the overview: Look at overall engagement rates and impressions.
  • Dive into specifics: Analyze STR, slide-by-slide engagement, and completion rates.
  • Assess impact: Evaluate saves, shares, and CTR to understand your carousel's broader impact.
  • Identify patterns: Look for commonalities among your top-performing carousels.
  • Apply insights: Use your findings to inform future carousel creation and overall content strategy.

Case Study: Optimizing Carousel Performance

Let's look at a hypothetical example:

Fashion brand "StyleCo" noticed their carousel posts were underperforming. Upon analyzing their metrics, they discovered:

  • Low swipe-through rates (40%)
  • High engagement on product-focused slides
  • Low click-through rates on CTA slides

Based on these insights, StyleCo:

  • Reduced carousel length from 10 to 6 slides
  • Led with product-focused content
  • Incorporated CTAs earlier in the carousel

Results after one month:

  • Swipe-through rates increased to 75%
  • Overall engagement rose by 30%
  • Click-through rates improved by 50%

Conclusion: Data-Driven Carousel Optimization

By focusing on these critical metrics and taking a holistic approach to carousel analytics, you can continuously refine your strategy and create content that truly resonates with your audience. Remember, the goal isn't just to chase numbers but to use these insights to deliver more value to your followers.
