SEO issues due to windowPageData

[ankurparihar]

Hi team,

we're facing SEO issues for our Gatsby site,

[Gatsby v3]

Google search console is reporting 404 pages. Which is just pages getting indexed with wrong url.
For example, https://share.market/blog/what-are-wealthbaskets/ will be indexed as https://share.market/what-are-wealthbaskets/ (without the /blob/ path-prefix).

The only information on this page that can cause this we found was the CDATA coming from this script block

<script id="gatsby-script-loader">/*<![CDATA[*/window.pagePath="/what-are-wealthbaskets/";/*]]>*/</script>

We're unsure if Google crawls this data as well!

We found a possible location where gatsby injects it - https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/cache-dir/static-entry.js#L424C11-L424C25

The script has unique id - gatsby-script-loader

We would like to know

• Does this really affect seo?
• is there any reason for not adding path-prefix like - ${__BASE_PATH__}${pagePath} or ${pathPrefix}${pagePath}, whichever is application, (not sure about gatsby-internals)
• is it good idea to delete this script?
• if yes, what will be the good way to delete the script (onPreRenderHTML seems to be the right approach)
