Description

The addition of the Gatsby Head API was a great feature, but as oppose to React Helmet it pollutes the inserted scripts with attributes like data-gatsby-head="true" causing issues on search engines.

For instance on the following implementation:

export const Head = () => (
  <>
      <script type="application/ld+json">
          {JSON.stringify({"@context":"http://schema.org","@type":"Hotel"})}
      </script>
  </>
  )

I would expect a clean output on the header:

<head>
    <script type="application/ld+json">{"@context":"http://schema.org","@type":"Hotel"}</script>
</head>

Nonetheless the output is:

<head>
    <script type="application/ld+json" data-gatsby-head="true">{"@context":"http://schema.org","@type":"Hotel"}</script>
</head>

Note the data-gatsby-head="true" attribute, this messes up Google's structured data recognition, although it is recognized by structured data validators it doesn't work well on Google's search results, probably because they use some kind of regex to parse the schemas.

Reproduction Link

Steps to Reproduce

Go to the provided sandbox link.
Take a look at the src/pages/index.js and see how the API pollutes the HEAD script adding data-gatsby-head="true" to the generated script, making it useless for Search engines, or at least for Google's structured data/enriched search results).

Expected Result

<head>
    <script type="application/ld+json">{"@context":"http://schema.org","@type":"Hotel"}</script>
</head>

(Expecting a clean output, not made up attributes like:data-gatsby-head="true")

Actual Result

<head>
    <script type="application/ld+json" data-gatsby-head="true">{"@context":"http://schema.org","@type":"Hotel"}</script>
</head>
