This factor reports whether a page carries an @type of RadioStation in its raw HTML — a simple 1 (present) or 0 (absent). It is a text pattern-match on the source, not a validated JSON-LD graph, so a stray matching string can register a 1.

What it measures
The factor records whether RankGear finds an @type value of RadioStation in the page’s raw source. RadioStation is the schema.org type used to describe a broadcast radio station — its call sign, frequency, coverage area, owner, schedule, and listening details. A page that carries this markup returns 1; a page without it returns 0.
How RankGear measures it
RankGear searches the raw HTML for the string "@type": "RadioStation", allowing flexible whitespace around the colon and optionally accepting a schema: prefix on the value. Matching is case-insensitive, so capitalization differences do not change the result.
What RankGear looks for
"@type": "RadioStation"
"@type":"schema:RadioStation"| Value | Meaning |
|---|---|
| 1 | A RadioStation @type string was found in the raw HTML. |
| 0 | No matching RadioStation @type string was present. |
How to optimize it
Use RadioStation only for a genuine radio station, and populate it with an accurate call sign, frequency, coverage area, owner, schedule, and listening details. Every property should reflect content a user can verify on the page itself. Because the detector only confirms the string is present, treat a 1 as evidence that the markup exists — not proof that it is complete or correct. If your page is not about a radio station, this factor is simply not applicable; there is no benefit to adding the type where it does not belong.
Important considerations
- The detector pattern-matches source text rather than validating a full JSON-LD graph, so a well-formed schema is not required for a 1.
- A matching string that sits outside valid JSON-LD — in a comment, an example, or unrelated text — can still produce a 1.
- Capitalization differences do not affect detection; matching is case-insensitive.
- Validate the complete structured data independently with a schema validator; this factor does not confirm correctness.
- This is a prioritization signal that relates to positions within a measured result set — it does not, on its own, cause a page to rank.
