How to block or allow YandexScreenshotBot

Put the robots.txt rule in the file at the root of every domain and subdomain, for example https://example.com/robots.txt. The token YandexScreenshotBot is matched case-insensitively. robots.txt alone may not stop YandexScreenshotBot, so add the Nginx, Apache or Cloudflare rule as well.

robots.txt: block

# Block YandexScreenshotBot
User-agent: YandexScreenshotBot
Disallow: /

robots.txt: allow

# Allow YandexScreenshotBot
User-agent: YandexScreenshotBot
Allow: /

robots.txt: partial

# Keep YandexScreenshotBot out of private areas only
User-agent: YandexScreenshotBot
Disallow: /wp-admin/
Disallow: /cart/
Disallow: /checkout/
Disallow: /my-account/
Allow: /

Nginx

# Nginx: return 403 to YandexScreenshotBot
if ($http_user_agent ~* "(YandexScreenshotBot)") {
    return 403;
}

Apache

# Apache .htaccess: return 403 to YandexScreenshotBot
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} (YandexScreenshotBot) [NC]
RewriteRule .* - [F,L]

Cloudflare WAF

# Cloudflare > Security > WAF > Custom rule, action: Block
(http.user_agent contains "YandexScreenshotBot")

How to verify real YandexScreenshotBot traffic

Reverse DNS check: look up the request IP, confirm the hostname ends in yandex.ru, yandex.net, yandex.com, then look up that hostname and confirm it returns the same IP.

# 1. Reverse lookup: the hostname must end in yandex.ru, yandex.net, yandex.com
host REQUEST_IP
# 2. Forward lookup: must return the same REQUEST_IP
host HOSTNAME_FROM_STEP_1

YandexScreenshotBot FAQ

YandexScreenshotBot identifies itself with the robots.txt token "YandexScreenshotBot". A typical request header reads: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/W.X.Y.Z* Safari/537.36 (compatible; YandexScreenshotBot/3.0; +http://yandex.com/bots)

Partly. YandexScreenshotBot fetches pages because a user asked for them, and Yandex says robots.txt rules may not apply to those user-requested fetches. Use a firewall rule if you must stop it.

Blocking a search engine crawler removes your pages from that search engine's results. AI features built on that search index, such as Google AI Overviews and AI Mode on top of Googlebot, also lose access to your pages.

Add two lines to the robots.txt file at the root of each domain and subdomain: "User-agent: YandexScreenshotBot" followed by "Disallow: /". The token is case-insensitive. Changes can take up to 24 hours to be picked up.

Yes. Run a reverse DNS lookup on the request IP; a real YandexScreenshotBot request resolves to yandex.ru, yandex.net, yandex.com, and a forward lookup of that hostname returns the same IP.

Search your server access log for "YandexScreenshotBot", for example with: grep -i "YandexScreenshotBot" access.log. The AI Log File Analyzer by Justin Hà counts visits per AI bot from an uploaded log file.
