Where does Seznam.cz get its results?
Own crawl and own index. The English help describes search.seznam.cz as an independent web search engine run by Seznam and fed by the SeznamBot crawler[12, 28], and Seznam Webmaster reports the pages held in the search index[17]. No fetched page states that web results are licensed from another engine. Blocks outside the natural results (teasers, smart cards) come from Seznam's own services, partners and public databases such as Wikipedia[20, 21, 24]. Seznam accepts IndexNow pings, which participating engines pass on to each other[29].
Engines that use results from Seznam.cz
The research records no engine that takes its general results from Seznam.cz or is built on it by the same company.

Does Seznam.cz use structured data?
The research records documented support for JSON-LD and Open Graph for Seznam.cz. It records 10 rich result types, listed in the next section.
| Format | Documented support | What the research records |
|---|---|---|
| JSON-LD | Yes | Every code example on the overview and the nine snippet pages is a script block of type application/ld+json. The string JSON-LD itself never appears; Seznam speaks of schema.org as a type of structured data.[1] |
| Microdata | Not documented | Not named on the overview, the nine snippet pages, the image search page or the two 2021 blog posts. Not documented, which is not the same as not supported. No itemscope or itemprop example anywhere.[1] |
| RDFa | Not documented | Not named on the overview, the nine snippet pages, the image search page or the two 2021 blog posts. Not documented, which is not the same as not supported.[1] |
| Open Graph | Yes | Named next to schema.org as one of the two types Seznam works with. Used mainly to fetch image previews for products, articles and videos and to fill gaps; schema.org has priority. Documented on five of the nine snippet pages (product, video, article, recipe, event) and for image search.[1] |
| Microformats | Not documented | Not named on the overview, the nine snippet pages, the image search page or the two 2021 blog posts. Not documented, which is not the same as not supported.[1] |
| Twitter Cards | Not documented | Not named on the overview, the nine snippet pages, the image search page or the two 2021 blog posts. Not documented, which is not the same as not supported.[1] |
“Not documented” means the pages read do not say; it does not mean the format is ignored.
Other formats and channels
data-vocabulary.orgNot documented
The product page calls it an old standard still seen on some sites and advises moving to schema.org. It does not say whether such markup is still read or when it stops.[2]
RSS and Atom feedsDocumented
A feed format, not page markup. Seznam reads RSS 0.9x, 1.0 and 2.0, CDF, Atom 0.3 and 1.0, announced with a link rel=alternate element or the add-page form.[26]
Which rich results can Seznam.cz show?
The research records 10 rich result types for Seznam.cz: 10 active. Each entry shows the schema.org types it is documented for, where the research records them. Valid markup can make a page eligible; it does not guarantee the result.

Formats: JSON-LD, Open Graph
Image search vertical. Image links found in structured data weigh more than images found incidentally in the page. The page advises ImageObject with description, caption, width and height, or the Open Graph equivalents, and a main type that matches the page content (Product and Review are the examples given). The page shows no markup example, so the JSON-LD syntax is taken from the structured data overview it points to[1]. No required labels.

Documented for: NewsArticle (main type), Article, ImageObject and ImageGallery
Recommended:
dateCreated, dateModified, datePublished, description, hasPart, headline, image, name, thumbnail, thumbnailUrlWhere: not stated
Formats: JSON-LD, Open Graph
Natural results, article search and the news teaser. Shows title, preview image, description and publication date. No required or recommended labels on the page. NewsArticle or a fitting subtype is advised; Article is the generic fallback. The earlier of datePublished and dateCreated is used; dateModified is a fallback only. hasPart with an ImageGallery needs at least five images. Open Graph fallback: og:image and article:published_time; schema.org has priority. Preview cropped to 16:11, ideally 320x220 px or larger; over 3200x3200 px discarded.
How does Seznam.cz crawl the web?
The research lists 6 crawler tokens for Seznam.cz: the names a site uses in robots.txt rules, with what each one does where the source says.
How do I test my markup for Seznam.cz?
Testing tools the research records for Seznam.cz:
Schema Markup Validator (schema.org), the tool every Seznam snippet page links to[2]
Google Rich Results Test, the tool a 2021 Seznam blog post pointed to before the help switched to validator.schema.org[32]
Seznam Webmaster (crawl and index reports only; no structured data report is documented)[17]

What does Seznam.cz ask of site owners?
Its own vocabularies, tags and feeds
seznambot meta tag
Seznam-specific robots meta name. Documented with nosnippet (no excerpt, image preview or structured data extras in the result; also the opt-out for AI answers and summaries) and nofeaturedsnippet. The Meta tag robots page[15] says the SeznamBot meta name is not supported, so the help disagrees with itself on scope.[16]
data-nosnippet attribute
HTML attribute on span, div or section that keeps the marked part of a page, including structured data sections, out of the snippet. Any value switches display off, even the value false.[16]
Seznam-Extended, AI and MachineLearning robots.txt tokens
User-agent tokens that, with Disallow: /, stop Seznam from building AI answers from the site. Any one of the three is enough. They are control tokens, not separate crawlers with their own user-agent strings.[14]
seznam-wmt verification
Site ownership check for Seznam Webmaster: a meta tag named seznam-wmt or a text file named seznam-wmt-<code>.txt.[17]
What could not be verified?
These claims about Seznam.cz came up in the research, but no page that could be read confirms them. They are kept apart, and nothing above rests on them.
Seznam parses schema.org written as Microdata.
Why it is open: No page names Microdata or shows itemscope or itemprop. Nothing says it is unsupported either.
Seznam parses schema.org written as RDFa.
Why it is open: RDFa is never mentioned. Nothing says it is unsupported either.
Seznam reads Twitter Cards or Microformats.
Why it is open: Neither is mentioned on any fetched page.
data-vocabulary.org markup is still read for product snippets.
Why it is open: Both call it an old standard and advise schema.org. Neither states a cut-off or a flat yes or no.
Seznam has its own structured data testing tool, or a structured data report inside Seznam Webmaster.
Why it is open: None is mentioned; the snippet pages send owners to validator.schema.org. Absence of a mention is not proof.
SeznamBot renders JavaScript, so JSON-LD injected by script is read.
Why it is open: No fetched page says whether the crawler executes JavaScript.
FreshBot has its own user-agent string or robots.txt token.
Why it is open: FreshBot is named as the fast crawler for news and RSS, but no string or token is given for it.
The robots.txt user-agent match for SeznamBot is case-insensitive.
Why it is open: Examples use both SeznamBot and Seznambot; neither page states the matching rule.
The seznambot meta name is honored for robots directives in general.
Why it is open: Source 15 says the SeznamBot meta name is not supported; sources 16 and 14 document it for nosnippet and nofeaturedsnippet. The help contradicts itself, so only those two values are recorded.
Structured data raises the chance of a page being used as a source for Seznam AI answers.
Why it is open: Source 24 lists structured or verified data among the source selection criteria but names no vocabulary, type or property.
Types outside the documented snippets (BreadcrumbList, Organization, LocalBusiness, JobPosting, standalone Review and others) produce no Seznam result feature.
Why it is open: Not documented is not the same as not supported. These are recorded as not documented, not as unsupported.
NewsArticle markup alone gets a site into the Seznam news teaser.
Why it is open: Source 4 says article data is used in the news teaser; source 20 says the teaser shows sites from the Seznam Partner service. The entry condition is membership, and the role of markup is not spelled out.
A Seznam Partner crawler reads JSON-LD Article data for geographic targeting of content.
Why it is open: Partial fetch: the PDF text came back as undecodable compressed streams. Only link targets were visible (schema.org/Article, a Google testing tool, Wikidata). It is also a different product from web search.
