Checks linked PDF sizes against Googlebot 60MB truncation limit

| | |
|---|---|
| **Rule ID** | `crawl/pdf-size` |
| **Category** | [Crawlability](/rules/crawl) |
| **Scope** | Site-wide |
| **Severity** | error |
| **Weight** | 4/10 |

## Solution

Googlebot truncates PDFs at 60MB—content beyond that limit is ignored during indexing. Split large documents into smaller parts, compress images within PDFs, or add a noindex X-Robots-Tag header if the PDF doesn't need to appear in search results.

## Options

This rule supports the following configuration options:

| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `warn_bytes` | number | `31457280` (30MB) | Byte size to trigger warning |
| `error_bytes` | number | `62914560` (60MB) | Byte size to trigger error (Googlebot truncation limit) |
| `max_pdfs_to_check` | number | `50` | Maximum number of PDF links to check |

### Configuration Example

```toml squirrel.toml
[rules."crawl/pdf-size"]
warn_bytes = 31457280
error_bytes = 62914560
max_pdfs_to_check = 50
```
