Has JSON-LD Optometric is a binary check that reports whether RankGear finds an @type value of Optometric 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 Optometric in the page’s raw source. Optometric is a schema.org medical-business type used to describe an optometry practice or eye-care service. 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": "Optometric", 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": "Optometric"
"@type":"schema:Optometric" (whitespace flexible, case-insensitive)| Value | Meaning |
|---|---|
| 1 | The @type marker for Optometric was found in the raw HTML source. |
| 0 | No matching marker string was present in the source. |
How to optimize it
Use Optometric only for a genuine optometric medical service, with accurate practitioners, credentials, services, location, and contact information. 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.
