Understanding Sustained Attention Rate (SAR)
Overview
Sustained Attention Rate (SAR) measures the percentage of viewers who stay and engage with your content beyond the initial scroll. A higher SAR means your content is grabbing and holding attention — not just getting seen but getting absorbed.
SAR is one of the most powerful signals in your analytics because it goes deeper than vanity metrics. A post with modest reach but high SAR is performing exceptionally well, while a viral post with low SAR may indicate clickbait that does not deliver value.
How SAR Is Calculated
Social Cascade calculates SAR by analyzing how your audience interacts with a post after their initial view. The metric combines signals such as:
- Dwell time — how long viewers stay on your content
- Meaningful engagements — comments, shares, and saves carry more weight than quick likes
- Scroll-stop behavior — whether viewers stopped scrolling to read or watch
SAR is expressed as a percentage. For example, a SAR of 4.2% means that roughly 4 out of every 100 viewers stayed and meaningfully engaged beyond the initial impression.
Where to Find SAR
- Go to your Analytics page from the left sidebar.
- The SAR card in the Overview section shows your current rate and period-over-period change.
- The Reach vs SAR scatter plot (Insights section) plots every post so you can see which content achieves both high reach and high sustained attention.
- Individual post detail views also display SAR when you click a post in the Content Performance table.
What Is a Good SAR?
SAR varies by platform and content type. As a general guide:
| Range | Interpretation |
|---|---|
| Below 1% | Content is being seen but not holding attention. Consider stronger hooks or more relevant topics. |
| 1% – 3% | Average — solid foundation to build on. |
| 3% – 6% | Strong — your content is resonating well with your audience. |
| Above 6% | Exceptional — these posts are worth studying and replicating. |
Tips for Improving SAR
- Lead with value. The first line or first three seconds should promise something specific.
- Write for your audience. Content aligned with your audience interests (your patients, referrers, or community) naturally holds attention longer.
- Use storytelling. Personal anecdotes and patient-journey stories (de-identified and HIPAA-compliant) drive sustained engagement.
- Encourage comments. Posts that ask a thoughtful question tend to have higher SAR because viewers pause to read and respond.
FAQ
Q: Why is my SAR showing as empty?
A: SAR requires posts to have been live for at least 24 hours so Social Cascade can collect enough interaction data. Check back after your recent posts have had time to accumulate engagement.
Q: Does SAR count on every platform?
A: SAR is calculated for Facebook, Instagram, TikTok, and YouTube. Platform-specific signals vary, but the combined metric gives you a cross-platform view.
