What it does

Fetches content for the Seznam.cz search engine.

SeznamBot is a robot (also known as web crawler or web spider) – a program that retrieves content for our search engine.

Seznam.cz

User agent

Requests from Seznam Bot carry user agents like these:

SeznamBot/3.0 (+http://fulltext.sblog.cz/)

Mozilla/5.0 (compatible; SeznamBot/3.2; +http://fulltext.sblog.cz/)

Mozilla/5.0 (compatible; SeznamBot/3.1-test1; +http://fulltext.sblog.cz/)

Device Detector identifies it with this pattern (a case-insensitive regular expression):

SeznamBot|SklikBot|Seznam screenshot-generator

Anyone can put any name in a user agent. Where the operator publishes IP ranges, checking the request's address against them is the way to confirm a visit is genuine.

How to block or allow Seznam Bot

Add a group for its token to the robots.txt file at the root of your site. To keep it out of the whole site:

User-agent: SeznamBot
Disallow: /

To let it crawl everything, use an empty Disallow: or Allow: / instead. WordPress serves a virtual robots.txt that many SEO plugins let you edit. A real robots.txt file uploaded to the site root takes its place.

User-agent: SeznamBot Disallow: /

Seznam.cz

SeznamBot fully complies with the robots exclusion standard

Seznam.cz

robots.txt is a request, so it only works on crawlers that honour it. A bot that ignores it has to be blocked at the server or firewall, by user agent or IP address.

How Vireo counts Seznam Bot

Vireo keeps requests from Seznam Bot out of your pageviews and visitors and counts them on its bot report under Search engines, so you can see how much it left out rather than wonder why your server logs show more traffic.

Checked by running Vireo Analytics' own bot filter over Seznam Bot's user agents.
