Gatsby, the headless CMS marvel, alongside gatsby-plugin-advanced-sitemap makes generating a robust sitemap.xml file a breeze.

The plugin supports excluding pages with either by slug or with clever regular expression.

However in my case, I have 2 collections of User-Generated Content pages:

  • the collection A, with pages that need to be hosted, and indexed,
  • the collection B, with pages that need to be hosted, but NOT indexed.

The B collection has not a slug pattern making them identifiable with a regular expression.

Question

How to exclude the collection B from indexation?

Files that you don't include (or exclude) in your sitemap.xml can be indexed too if their robotx.txt allows Google's robots with an index attribute, or if the links from other pages to the page have a follow attribute.

Regarding your question, the plugin allows you to add a exclude array of pages that won't be added in your sitemap.xml despite being retrieved by your query. So, in your gatsby-config.js:

{
      resolve: `gatsby-plugin-advanced-sitemap`,
      options: {
        query: `{}`, // your query
        mapping: {}, // add if needed
        exclude: [
          `/dev-404-page`,
          `/404`,
          `/404.html`,
          `/offline-plugin-app-shell-fallback`,
          `/terms-and-conditions`,
          `/terms-of-use`,
          `/cookie-policy`,
          `/privacy-policy`,
          /(\/)?hash-\S*/,
        ],
        createLinkInHead: true,
        addUncaughtPages: true,
        additionalSitemaps: [], // add if needed
      },
    },

Ideally, your excluded pages may follow a regular expression way to be excluded automatically when generated. However, if don't, as the code above shows, you can add manually. In this case, nor /terms-of-use, /cookie-policy, or /privacy-policy won't be added in your sitemap.xml.
