# How fresh is my data?

> Trackbase runs every prompt once every 24 hours on each model. Learn when answers arrive and why the current day looks emptier than yesterday.

Trackbase collects data on a daily rhythm. Knowing that rhythm explains why today often looks different from yesterday, and when a new prompt or page shows its first results.

## Prompts and answers

* Every active prompt runs once every 24 hours on each model you track.
* Answers do not all arrive at the same moment. Some models return an answer directly, others are collected later, so a day fills up gradually.
* If a prompt runs more than once on the same model on one day, the first run counts in your metrics. That keeps daily numbers stable.

## Why today looks emptier

The current day is still collecting answers, so its numbers are incomplete until the day is over.

* The trend chart on the dashboard shows a 7-day moving average and leaves out the current day.
* The visitor timeline also shows completed days only.
* Period numbers on the metric cards can include today.

Compare completed days with completed days. To judge a change, wait until the day is over.

## Website data

* **Visitor analytics**: visits are recorded as they happen. The number for today updates live, while the timeline shows completed days.
* **Crawler analytics**: crawler requests come in as they happen. The request log covers the last 30 days.
* **Page tracker**: each tracked page is checked when you add it and once a day after that.

## After you change something

| Change | When you see it |
| - | - |
| New prompt | With its first run, within a day. |
| New model | From the day it starts running. Blended averages can shift, see [why did my score drop?](https://academy.trackbase.ai/why-did-my-score-drop.md). |
| New alias | In answers analyzed after the change. |
| New page on your website | First in crawls, later in citations, then in clicks. Follow it in the [Page tracker](https://academy.trackbase.ai/page-tracker.md). |
