## Should you block Baiduspider?

Allow it unless you want out of that search engine. Blocking a major search crawler removes your pages from its results.

## How to block Baiduspider in robots.txt

Add a group for its tokens to robots.txt at the root of your site.

A bot follows only the group that names it, so it ignores your `User-agent: *` rules once it has a group of its own. Repeat any paths you also want kept from it there.

```
User-agent: Baiduspider
User-agent: Baiduspider-image
User-agent: Baiduspider-video
User-agent: Baiduspider-news
Disallow: /
```

## How to verify a request is really Baiduspider

Anyone can send any user agent, so the string alone proves nothing.

Or check by reverse DNS: look up the hostname of the request’s IP, confirm it ends in `baidu.com` or `baidu.jp`, then look that hostname up again and confirm it points back to the same IP.

## See when Baiduspider reads your site

Bots don’t run JavaScript analytics, so a script tag never sees them. invisit records crawler reads on the server instead, through its server SDK or a Cloudflare Worker, and shows which bots read which pages, next to your visitors.
