Has JSON-LD Periodical is a binary check that reports whether RankGear finds an @type value of Periodical in a page’s raw HTML source. It returns 1 when that string is present and 0 when it is not — but because it matches source text rather than parsing a JSON-LD graph, a match tells you only that the markup appears in the source, not that the structured data is valid.

What it measures
This factor reports whether RankGear detects an @type value of Periodical in the page’s raw source. Periodical is a schema.org type used to describe a periodical publication — a magazine, journal, newspaper, or similar title issued on a recurring basis. A result of 1 means the marker string was found in the HTML; 0 means it was not. It is a presence signal, not a quality or validity score.
How RankGear measures it
RankGear searches the raw HTML for "@type": "Periodical", tolerating flexible whitespace around the colon and optionally allowing a schema: prefix. Matching is case-insensitive, so capitalization differences do not affect the result. The check reads the raw source text directly rather than validating a parsed JSON-LD graph.
What RankGear looks for
"@type": "Periodical"
"@type":"schema:Periodical" (whitespace flexible, case-insensitive)| Value | Meaning |
|---|---|
| 1 | The @type marker for Periodical was found in the raw HTML source. |
| 0 | No matching marker string was present in the source. |
How to optimize it
Use Periodical only for a genuine periodical publication, with an accurate publisher, ISSN, publication frequency, issues, coverage, and access details. Every property should reflect content that users can verify on the page. Because the detector reports presence rather than correctness, treat a result of 1 as an observation that the markup exists in the source — not a target to hit by inserting the string. Adding the marker without real, matching structured data does not improve the underlying page.
Important considerations
- The detector pattern-matches source text instead of validating a JSON-LD graph.
- A matching string that sits outside valid JSON-LD can still produce a 1.
- Capitalization differences do not affect detection.
- Validate the complete structured data independently with a dedicated schema validator.
- This factor tracks a signal that relates to position within a measured result set; it does not, on its own, cause a page to rank. Correlation is not causation.
