Seznam Search referrer traffic
Seznam is a leading Czech portal and search engine that competes strongly with Google in the Czech Republic. Organic clicks reach your site as search.seznam.cz referrals, identifying the engine, but like other engines Seznam strips the query from the Referer header.
What this means
Seznam is a major Czech portal whose search engine holds a significant share in the Czech Republic, where it is one of the few national engines to seriously rival Google. Organic clicks from its results reach your site as referrals from search.seznam.cz.
For sites targeting Czech audiences, Seznam is an important organic source, and distinguishing it from Google reveals how much of your Czech demand comes from the local portal.
Why the query is missing and what to do
Seznam, like other major engines, omits the search query from the Referer header — you see search.seznam.cz but never the keyword. Keyword data must come from the engine's own webmaster tooling, not your referrer log.
Organic results cannot be UTM-tagged because you do not control the SERP. Reserve UTM tags for links you own, including any Czech-market campaigns. Treat Seznam organic clicks as an opaque source identified only by host.
- Host you may see: search.seznam.cz
- Channel: organic search (not a campaign)
- Query is stripped — keyword data is not in the referrer
How it appears in analytics and logs
A referrer on search.seznam.cz means a visitor clicked an organic Seznam result. It is organic search, not a campaign, and the keyword is absent because Seznam strips the query like other engines.
Diagnostic use case
Confirm that organic visits come from Seznam rather than Google in the Czech market, and file them as organic search traffic with local-portal context.
What WebmasterID can help detect
WebmasterID groups search.seznam.cz referrals into the organic-search channel with other engines, so Czech-market discovery is visible without log parsing and stays separate from social or direct.
Common mistakes
- Trying to UTM-tag Seznam organic results — you cannot tag a SERP you do not control.
- Assuming Google dominates Czech search — Seznam holds significant share.
- Filing Seznam as generic referral rather than organic search.
Privacy and accuracy notes
Attribution uses only the Referer host. The searcher's query and identity are not exposed or reconstructed. WebmasterID records the engine as an organic-search channel, never a person.

- Yandex search referrer
Yandex is a leading search engine in Russia and is used across several neighbouring regions. A yandex referrer — on yandex.ru, yandex.com, or another regional domain — typically signals organic search from that audience. The query is not in the referrer; Yandex Webmaster is the source for query-level data.
- Yahoo Search referrer traffic
Yahoo Search referrals come from people clicking your page in Yahoo's web results at search.yahoo.com. Yahoo's web results have long been powered by partner search technology, so the experience resembles other engines, but the referrer host is what identifies the source. Like all modern search engines, Yahoo strips the query from the Referer header, so you see the engine but not the keyword.
- Referrer grouping into channels
Analytics platforms do not report every raw referrer separately — they map hosts into channel groups such as organic search, paid, social, referral, email, and direct. Understanding the default rules explains why a click ends up in one bucket versus another, and why a custom source can be misfiled until you adjust the grouping.
