What SeznamBot does
SeznamBot is the web crawler that retrieves content for the Seznam.cz search engine. It identifies itself with a user-agent string containing SeznamBot/4.0. A variant, FreshBot, is a fast crawler that indexes pages and RSS feeds containing fresh content, commonly found on news sites. Seznam publishes the crawler's IPv4 and IPv6 address ranges, also available in JSON format, along with reverse DNS hostname patterns for verification.
How to control SeznamBot
Target SeznamBot in your robots.txt with the SeznamBot token. Rules apply per bot, so you can allow this one while blocking others, or the reverse.
Allow SeznamBot
User-agent: SeznamBot
Allow: /Block SeznamBot
User-agent: SeznamBot
Disallow: /Seznam publishes the crawler's IP ranges (including a JSON version) and its reverse DNS hostnames, which follow patterns like fulltextrobot-77-75-77-xxx.seznam.cz, so requests claiming to be SeznamBot can be verified.
How to identify SeznamBot
Temso identifies SeznamBottraffic by matching the request's User-Agent header against this pattern. User-agent strings can be spoofed, so treat a match as an indication, not proof.

About Search Engine Crawlers
Classic search indexers that now also feed AI features: Google's AI Overviews and AI Mode build on Googlebot's index, and Microsoft Copilot builds on Bingbot's.
Blocking these removes you from both traditional rankings and the AI answers built on top of those indexes, usually the most costly block of all.
