# Analyze spike dates with Spike analysis

> Pick a date when impressions jumped and see the surrounding trend, the AI summary, and the posts behind it.

**Spike analysis** finds the days when impressions or mentions jumped, then shows what was happening on that day: the posts, themes, and possible outside events behind the jump.

## Before you start

* **Queries:** Prepare at least one Query. If you use more than one, they must be the same type (Brand, Product, or Topic).
* **Permissions:** Viewer or higher can view results and source posts. Editor or Admin can create analyses and run **Analyze** on a date.
* **Analysis runs per date:** Creating a Spike analysis doesn't analyze anything yet. You choose a date on the chart and run **Analyze**.

## Analyze a spike date

1. In the sidebar, open **Social intelligence > Spike analysis**. Select **Start analysis** to create one, or open an existing one.
2. Adjust the chart's date range to find the jump.
3. Select the date where impressions or mentions peaked.
4. Select **Analyze**.
5. When processing finishes, open the result.
6. Review the Key Driver, themes, and source posts.

> Select the star (★) at the top right of an analysis to add it to **Favorites** in the sidebar.

## Read the results

### 1. The 5-day window (D-2 to D+2)

The report shows impressions, posts, and engagements for five days: two days before the spike, the spike date, and two days after. This tells you whether it was a one-day jump or part of a longer wave.

### 2. The spike date

* **Key Driver:** An AI summary of the content and conversation on the spike date, pointing to what most likely drove the jump.
* **Themes and outside events:** Links the conversation to possible real-world triggers, such as a launch, a creator trend, press coverage, or an event.
* **Source posts:** The posts with the most impressions and engagement that day. Open any post to see the video, audio, and comments.

> [!NOTE]
>
> The 5-day numbers give context, but the **Key Driver** and themes cover only the **selected spike date**. Treat the Key Driver as a strong lead, not proof of what caused the spike, and check the source posts before drawing conclusions.

## Troubleshoot

| Symptom | What to check |
| :- | :- |
| **Analysis stays "In progress"** | Analysis can take a little while. Don't submit the same date again; refresh the page shortly. |
| **Analyze isn't available for a date** | The date may be today (not yet complete) or have too few posts. Choose a past date with a clear spike. |
| **Analysis shows "Failed"** | Select **Analyze** on the same date to try again. |
