# Why did my score drop?

> Most drops in a Trackbase score come from a changed setup, not from AI changing its mind. Check these five causes in order to find out.

Your visibility score or another Trackbase metric fell and you want to know whether it means anything. Most drops come from one of five causes. Check them in this order, because the most common ones are also the quickest to rule out.

One fact explains most of them: scores are averages over all answers, and an answer that does not mention your brand counts as 0. Anything that adds such answers pulls the average down, whether or not a model changed how it sees you.

> [!TIP]
>
> When several metrics fall by a similar percentage on the same day, a changed setup is the most likely cause. Start with causes 1 to 3.

## 1. You added or removed prompts

New prompts where you are not mentioned yet add answers that score 0, on every model, every day. Your average drops on the day they start, while nothing changed for your existing prompts. Removing prompts where you scored well has the same effect.

**How to check**: compare the date of the drop with the date you changed your prompts.

A drop from new prompts is healthy. You are now measuring ground you want to win.

## 2. You added a model

Models score differently, and the dashboard blends them. Adding a model where you are rarely mentioned lowers the blended average from its first day.

**How to check**: use the model filter to look at each model separately. If every model you already tracked is stable, the mix changed, not your visibility.

## 3. The period is not complete

The current day is still collecting answers. Trackbase leaves it out of the trend line for that reason, but a short period that ends today can still look weaker than it is.

**How to check**: choose a longer period, or look again tomorrow.

## 4. Too few answers

With a handful of prompts on one or two models, each day rests on very few answers. One answer that skips your brand moves the number visibly, and it often comes back the next day.

**How to check**: widen the period. A dip that disappears over 30 days was noise. The lasting fix is more prompts.

## 5. Your competitor list changed

Share of voice is your part of all mentions of you and your competitors. A new competitor adds its mentions to the total, so your share falls.

**How to check**: if share of voice dropped but your visibility score held, look at the [competitor list](https://academy.trackbase.ai/competitors.md).

## When the drop is real

If none of the five apply, something changed in the answers. It is rarely everywhere at once.

1. Use the model filter to find which model fell.
2. Go through your prompts to find where.
3. Open those prompts and compare recent answers with older ones. Look for who is named instead of you and which sources the answers now cite.

A slow decline on one model across many prompts usually means its sources moved away from you. That is content work. Use [Actions](https://academy.trackbase.ai/actions.md) and the [Page tracker](https://academy.trackbase.ai/page-tracker.md) to turn it into tasks.
