Understanding Sustained Attention Rate (SAR)
Overview
Sustained Attention Rate (SAR) measures the percentage of viewers who stay and consume 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.
