## What is SERP?

SERP is the Google search results page for a keyword. In HaloX, each keyword SERP snapshot is evidence for rank, Top 10 visibility, AI Overview, PAA, and brand or competitor domain detection.

## Metrics from a SERP snapshot

| Metric        | Meaning                                                 | Basis                                                               |
| ------------- | ------------------------------------------------------- | ------------------------------------------------------------------- |
| Rank          | Where your page appears in search results               | Lower is better; top 10 is usually first-page range.                |
| Top 10        | Keywords where your domain ranks in the top 10          | Counts keywords with best rank 10 or lower.                         |
| SERP features | Special search-result areas                             | AI Overview, PAA, featured snippets, local, shopping, and more.     |
| AIO           | Whether Google AI Overview appears and cites your brand | Read detection, brand citation, and competitor citation separately. |
| PAA           | People Also Ask questions                               | Question demand, not search volume.                                 |
